Re: [Flightgear-devel] Terrain self-shading
Hi Thorsten, I presume the balance between ambient and diffuse should vary with the weather. A clear sky gives harsh shadows and overcast sky with several layers of clouds gives barely any shadows (dull day in photographer speak). Your results (which are really pretty) are likely to be unrealistic with bad weather and perhaps a middle term as it is now will fit more situations if the balance is not adjustable.

Re: [Flightgear-devel] A collection of questions
Hi Thorsten, De: Renk Thorsten If I may bother everyone again - here's my current list of open questions. Any help or pointers would be appreciated: * Where do the runway and taxiway lights enter the rendering scheme? They need to be fogged consistently with the rest of the scene, but I do not know where to set this - which effect are they using? Context: In low visibility scenes, lights remain visible to large distances because they go to the default fog color rather than the atmospheric light scattering fog color. See http://users.jyu.fi/~trenk/pics/catIIIb.jpg Light objects are built in simgear/scene/tgdb/pt_lights.cxx There effect is built in C++ in the getLightEffect function. It is not configurable as it is now. Ideally, this function should be replaced by a lookup in the material file to find a configurable effect. But I didn't thought about the implications of doing so. * Where does precipitation enter the rendering scheme? Context: I have received the suggestion to change the lighting of rain and snow to agree better with the environment lighting - but I don't know where the lighting for precipitation is defined in the first place. See http://www.flightgear.org/forums/viewtopic.php?f=69t=7358start=555#p176734 Precipitations use the OSG particle effect. I don't thing it is something configurable as the shader is coded in OSG C++ code. Maybe this is something we should try rewriting in order to make the lighting different. The implementation of the effect is in simgear/environment/precipitation.cxx * Why are the runway and taxiway designation signs using the terrain shader? Can (should) this be changed? Context: The terrain ubershader at high detail assumes that vertical surfaces need to be rock. If a sign is rendered by the terrain shader, the shader consequently makes the sign vanish and replaces it with rock unless the rock texture is explicitly set to 'off'. This could be hacked around by just setting it off for every sign, but I am thinking that a better solution would be to render these objects with a model shader because the features of a terrain shader do not really make sense in this context. See http://www.flightgear.org/forums/viewtopic.php?f=47t=18999 No idea. Certainly a shortcoming. * Can we generate more vertex attributes than tangents, normals and binormals? For instance, can we do components of the curvature? Context: Lots of vegetation patterns in nature are 'on the valley floors' or 'along a ridge'. In order to tag those with shader effects, one would need curvature. For instance, valley floors are defined by normal pointing upward and positive curvature, the ridges are defined by normal pointing upward and negative curvature. This would allow much more natural distributions of overlay patterns. Problem : it consumes GPU memory even if the technique requiring the extra attributes is not selected * How difficult would it be to expand the tree generating system to a multi-tier system in which we can in addition generate a circle of vegetation in the range of ~50-100 m for high resolution scenes landing off airfields? Do we generate the memory load from trees at tile loading time, or at tree loading time? Context: Would be very cool to have ;-) * Just how are the LOD ranges defined in the view menu used? I am genuinely confused, I understand that LOD bare sets the terrain, but that's the limit. Does anyone know? These properties were introduced by me back in 2004 when I began to populate the SFO area with static buildings. I originally provided 2 or 3 versions of the geometry in the same model selected by a range animation. Thanks in advance for any help with these!

Re: [Flightgear-devel] Shader organization for 3.0
A random idea : I can de-emphasize them by having one or two overlay textures continuous across a boundary, so they don't stick out dramatically at first sight as they would do without texture mixing, but I do not know how to make them really go away except in very specific cases (using vegetation ordering in altitude and gradient in the mountains) - the shader simply doesn't know where the seams are, so they can't be hidden. How about extending the BTG format to record for each vertex the distance to boundary (in tc unit). The terragear toolchain would compute it offline and the runtime loader would convey that value to the shader as a vertex attribute. Distance for each fragment would be interpolated in a varying. A generate clause in the effect file would control if that attribute is really needed to same GPU memory in case of simple effects not relying on this distance. BTW: fixed-function opengl as already the concept of polygon edge : we can express the fact that a triangle edge is a polygon edge in case of tessellation. It's a boolean attribute of the vertex.

Re: [Flightgear-devel] Shader organization for 3.0
De: Renk Thorsten thorsten.i.r...@jyu.fi Geometry shader can also process adjacency information if provided by the CPU through special primitives (GL_TRIANGLES_ADJACENCY and GL_TRIANGLE_STRIP_ADJACENCY) Oh, right - a geometry shader can probably receive a triangle as input, compute its center of gravity, shift all vertices outward by 5-10 m and return a slightly larger triangle to the vertex stage. I know very little about geometry shaders, but it'd be a nice reason to have a look. So, a sketch for a (probably rather unsophisticated scheme): * have a geometry shader make every triangle a little larger - in level terrain, we get then overlap of differently textured landclasses, and since we know how large we made the overlap region, we can later fade the textures in that region - in sloped terrain, we get artefacts as the enlarged triangles do not fit together properly, so * at the vertex shading stage, we need to determine if the terrain is flat or not - if the terrain is flat, we use the overlap region to blend textures later - if the terrain is a bit sloped, we shrink the overlap region (i.e. we tell the fragment shader to fade to alpha much faster) - if the terrain is very sloped, we reduce it to zero * at the fragment stage, we somehow tag fragments in the region where textures overlap and give them some alpha value - we end up with blended textures and (hopefullly manageable) artifacts What's not clear to me is how we determine if a fragment is close to a triangle edge or not. Somehow this requires to compare uninterpolated vertex coordinates with interpolated vertex coordinates, but it's not clear to me how the uninterpolated coordinates can be passed to the fragment stage. What's also not clear to me if this would ultimately fail due to z-fighting... Also, this scheme would operate on *any* triangle, regardless if it is actually at the landclass boundary or not. I do believe its operation would not show when there is no landclass boundary as one blends same with same texture. Feels somehow still... unsatisfactory. How about extending the BTG format to record for each vertex the distance to boundary (in tc unit). The terragear toolchain would compute it offline and the runtime loader would convey that value to the shader as a vertex attribute. Distance for each fragment would be interpolated in a varying. Well, yes - so then we know how far a fragment is from the boundary, but what we don't know is what the texture is I should blend into - so somehow we'd need to transport that, also allowing for edges in which n different textures meet... Ugly, ugly... First, from your sketch, I think you misunderstood where the gs fit. In fact it operates on the result of the vertex shader, and its output is directly rasterized to the fragment shader. But you can have a null vertex shader (that do nothing except outputting its input) and do the vertex work in the gs as you can have all the vertices of the primitive in the same function. But currently the gs is not able to tell if the edge of the current triangle processed is convex or concave, because it has no idea of the 3 adjacent triangles. The geometry shader specification adds new primitives with adjacency. See http://web.engr.oregonstate.edu/~mjb/cs519/Handouts/geometry_shaders.6pp.pdf (6th slide). That can be used to generate silhouettes if the normals don't point to the same direction. But that would require to modify the C++ code in order to push the adjacency information to the GPU. By the way, as a gs is able to create geometry, instead of expanding a single triangle, you can output the original triangle and a flat boundary around it using 3 quads (in fact 6 additional triangles). Combined with adjacency information, that way there would be no extra geometry for the edge shared by 2 triangles of the same landmass and only one when landmass differs. Anyway, I don't thing the using geometry shader without adjacency info is satisfactory for the reason you already exposed (z-fighting, hairy surface, etc) Regards, -Fred -- Master SQL Server Development, Administration, T-SQL, SSAS, SSIS, SSRS and more.

It should be trivial to extract these values from the ephemeris code. Thanks, that was what I was hoping for :-) It depends a bit on if Fred wants to do anything with the moon - my scheme would be fine with the angle of the moon above the horizon and the moon phase (or, as Curt explained, equivalently the relative angle between sun and moon) as properties. I think I have a brightness curve of moonlight as a function of phase somewhere, so from there I'd be good. However, if we want directional moonlight in Rembrandt, then I guess the info has to flow to the shader in a more direct way (like gl_LightSource[1].position) - in which case I'd use it from there. Don't wait for me. Anyway, sun direction and colors are given to shader via normal uniforms that are updated here (in Rembrandt mode only) : http://gitorious.org/fg/flightgear/blobs/next/src/Viewer/renderer.cxx#line1570 Moon equivalent should go the same way. I just don't have an idea on own to balance sun light and moon light without knowing the time of day or having test on the light direction. I suspect the difference in light intensity (dynamic range) doesn't fit in an 8-bit 3-component color. I was also thinking about replacing sun values by the one from the moon during night in the C++ code, without telling to the shaders. I didn't ponder on the cons of that approach thought.

Re: [Flightgear-devel] Moonlight reloaded
Hi Curt, But now with Rembrandt maybe we can begin to cast the earth's shadow onto the moon? What do you think Fred? :-) It should be just a matter of rendering two spheres inside an FBO and using the resulting shadow map when rendering the moon sphere to show moon eclipses, or altering the sun light with a shadow map lookup to render sun eclipses.

If you figure that one out, it'd be great. Right, that's absolutely the first item on my 'look at easy performance gains' list. I have in my Rembrandt TODO list to restore the use of a near and a far camera to reduce z-fighting. But Rembrandt needs a monotonic depth buffer, and erasing it in the middle of a frame is not an option. So I think we can render the near camera using a depth range (see glDepthRange) of (say) 0.0 - 0.1 and the far camera with a range of 0.1 - 1.0. This will have the advantage to allow the near camera to be rendered first. Mathias or Tim also suggested to look to logarithmic depth buffer but that is more demanding and needs a shader for all geometry (already true for Rembrandt, but not for the classical renderer).

Re: [Flightgear-devel] Depth buffers, render bins and passes
Hi Thorsten, De: Renk Thorsten thorsten.i.r...@jyu.fi I'm trying to understand why clouds can obscure hills and hills can obscure clouds properly. My individual bits of knowledge are: * clouds are drawn from outside in, because they are in a depth sorted bin, and this is why clouds obscure other clouds properly. * hills are not drawn from outside in but in some (unspecified) order, but they are drawn in two passes, and the second pass has depth functionlequal/function write-mask type=boolfalse/write-mask /depth declared which presumably does the trick of running a fragment only if its depth is lesser or equal to the buffered value but does not alter the depth buffer itself. There is no depth tag during the first pass, so the depth buffer seems to be doing something by default - at least write and perhaps also lequal testing? Unfortunately README.effects does not mention the depth buffer at all. This is correct Now, what I'm unsure about is the relative ordering of passes and rendering bins. Are the two passes of render bin 1 done before starting with render bin 2, or are first all passes 1 done for all render bins, then the passes 2? Clouds have a depth write-maskfalse/write-mask /depth tag in their single pass, so they don't modifiy the depth buffer, but there's also no lequal comparison specified - is this the default behaviour? Otherwise I simply don't see why a hill can possibly obscure clouds... Maybe the default is less. I need to check. Is it correct that if I want to insert any proxy for a cloud which is able to obscure terrain (i.e. does not require the terrain underneath to be rendered) this must go into pass 1 render bin 1 with no specific depth tag? What is the meaning of render bin -1 as specified for the first pass of terrain - should the cloud proxy rather go in there? -1 is before 1. No special meaning. Render bin numbers don't have to be positive. Quite in general - how is the precise ordering of the default rendering, and what buffers are available when? Thanks for any light anyone can shed on this. The scene is first traversed to collect objects, see if they fit in the view frustum and put them in render bins. This stage is called the cull traversal. Then render bins are sorted by their numbers and drawn in that order. When we declare multiple passes in an effects, all objects affected by the effect are duplicated the number of passes mentioned in the effect during the cull traversal. As each pass can have a render bin clause, all these duplicates are distributed in all the render bins before the draw stage. To summarize, all objects having a pass of render bin -1 are rendered before any object having a render bin 1. If an object have two passes, it is rendered twice, once with the objects of the same render bin than the first pass, once with the objects of the same render bin than the second pass. The second pass can be rendered before the first pass if the render bin numbers are inverted (the pass number has no rendering meaning).

If anyone else wants to have a go at converting model shaders or the runway shader, I can still try to help, but right now I've even started up Flightgear just once during the last 4 weeks, so coding is just not something I can do. Anyway - there are some ideas and observations which I made and where I wanted to follow up, and I thought I just put them up here so that they may be discussed. I'm interested in making the appearance of the scenery more realistic with improved light and procedural texturing, i.e. things that end up in the shaders. At least on my system, if I run any eye candy features, the bottleneck is shaders (I can render a normal scene from the ufo without any shader effects with about 200 fps, on the other hand rendering urban effect on the whole screen drives me down to ~5 fps - I'm sure various statements which have been made on this list that our performance would be CPU limited are based on something, it's just nothing I am able to experience on my system, on my system it's shaders, more specifically fragment shader). So, that's what I would like to address - making Flightgear faster while expensive shaders are on. My general understanding of the situation There's a tendency for all the high quality eye candy to end up in the fragment shaders - see urban effect, water sine wave shader or my procedural texturing. In some sense that's good, because that decouples performance from the visibility range (since the number of pixels doesn't change), but it may also be bad if that constant performance is too low. I don't know how it is for others, but when I switch urban effect on, it relies on not too many patches of urban terrain in my field of view - if ~1/5 of the scene is urban, I still get decent performance, but if all I see is urban it becomes unusable and single digit experience. I guess there's part of the reason Stuart spent so much time on random buildings... My point being, something like the urban effect doesn't really generalize, we can't put expensive stuff all into the fragment shader if we can anticipate that it will fill a lot of the scene. Shuffling some load into the vertex shader helps a lot in the near zone (where a triangle has many pixels, and they're all filled based on three expensive operations at the corners) but loses out at the far edge of the visual range (where several vertices may fall into a single pixel). At least on my system, some things only run with usable speed (provided the visibility doesn't exceed a limit) because there's load in the vertex shader, so there's virtue in making the vertex shader do stuff. My understanding of Rembrandt is that essentially all operations go to the fragment stage since geometry is rendered in one initial pass and then buffered. If the situation is fragment-shader limited in the default scheme, my guess is that it will be even worse fragment-shader limited in deferred rendering. But admittedly what I have to say about deferred rendering is a bit guesswork. Clouds are a bit of an unrelated topic, as they can be very heavy on the vertex shader (all the billboard rotations need to be

Hi!
I'm trying to build a port of FlightGear 2.6.0 on FreeBSD, and it
fails with the same error every time. What can possibly cause it?
I already contacted port maintainer, and he said the port should
build
fine. We tried reinstalling FLTK and the ports it depends on, but it
didn't help.

[Flightgear-devel] Re : Rembrandt Compatibility and Triple Monitor Configuration: Hardware Recommendations?
Hi Durk, Rembrandt sort of work in multiscreen: you'll get a correct scene but with shadows and lights misplaced. There should be a matrix offset or perspective divide problem, that I wasn't able to fix for the moment. If Tim, Mathias or anybody else could have a look, I would be very grateful. re hardware upgrade: look at the wiki page for the memory requirements. I currently have a GTX 470 and it runs dual fullscreen well. I recently switched from an i7 930 to an i7 3770 (latest generation) and it made a huge difference in term of framerate (about 33% gain). Tim and Mathias already said that we are CPU bound and I can confirm by experience. Anyway, if I was about to change GPU, I'd take a GTX 660 Ti or a GTX 670. BTW: I also tested an AMD 7750 and it works pretty well for the price. I got 20 fps in 1280x720 geometry. I wouldn't consider it for multiscreen though ( admitedly, I didn't try) Regards, -Fred http://wiki.flightgear.org/Project_Rembrandt -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Currently for 3D models we have approximately 30 to 40 tests (on the thumbnail, the textures, the XML, the AC3D...) running for each submission, and a visual check, to make sure that what is committed is right and not putting into danger our shared infrastructure.

Re: [Flightgear-devel] Rendering passes confusion - again
Hi Thorsten, I still haven't given up on the idea of 'masking' the terrain pixel shading by the cockpit, since even a very simple mask easily makes the system 50% faster for me. Lauri has kindly given me some instructions on how to use the stencil buffer - so the idea was to start by filling the stencil buffer with a mask whenever there is an opaque pixel in the model. In order to do so, I added this pass in front of the first pass declared in model-default.eff pass stencil functionalways/function value1/value passreplace/pass /stencil alpha-test comparisongequal/comparison value type=float0.99/value /alpha-test depth write-maskfalse/write-mask /depth /pass What happened is that I got the near camera rendered fine, but as good pretty much nothing from the far camera. I can insert the same code before the first pass declared in terrain-default.eff where it doesn't have any harmful side effects, the scene renders just fine. So the code as such isn't defunct. It seems I can insert no pass whatsoever before the first pass declared in model-default.eff without disabling the far camera. Which means there is something I don't understand at all. Is there absolute meaning to the passes, i.e. are all first passes done first, then the information obtained there is in the buffers and available for all other effects when the second passes run, or are passes only a means to establish relative order in the effect files? Why can't I add passes to model rendering, but I can to terrain, clouds or trees? I've tried to understand what is happening in CameraGroup.cxx, but I have no real clue - the whole context beats me, I don't even see where near or far camera are defined. Some explanations perhaps? The relevant code for passes is here : https://gitorious.org/fg/simgear/blobs/next/simgear/scene/material/Technique.cxx#line165 A pass is an OSG StateSet, a collection of OpenGL states that have a draw order ( the render-bin bin number ). This code renders geometry n times, one time for each pass. You have to understand that at this stage, geometry is only stored in collections and after all the scene is traversed, these collections (render bins) are sorted before the draw stage. The end result is that all geometry having a pass that have an order num of 0 is rendered before any geometry having a pass of higher order num. What can happen with the two cameras is that the stencil buffer is shared, but I don't think it is cleared between the rendering of the far camera and the rendering on the near camera, so you may end up accumulating both camera in a single buffer. If you want to experiment, try to change line 668 of renderer.cxx, and change : camera-setClearMask(GL_DEPTH_BUFFER_BIT); to : camera-setClearMask(GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); Regards, -Fred -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

The more involved effects (think lens flare and depth of field) may require more thinking, but these one were easy to do and are cheap to run.

Re: [Flightgear-devel] Ideas for terrain shader structure in 3.0
I don't know what is needed to launch it in Rembrandt.
A Rembrandt material shader (one that is bound to scene geometry) is structured
this way (Fragment shader) :
void encode_gbuffer(vec3 normal, vec3 color, int mId, float specular, float
shininess, float emission, float depth);
main() {
// Compute normal,
// albedo (without light or fog or scene ambient),
// specular luminance (or luminance of specular color),
// shininess,
// emission luminance,
// depth of fragment in eye space in range [0..1]
// set a material Id (1 : default, 254: water, 255: model ubershader)
// other values for material Id should be taken care in sunlight
shader and light shaders
#ifdef REMBRANDT
// call encode_gbuffer
encode_gbuffer(normal, albedo, materialId, specular, shininess, emission,
depth);
// no light or fog computation
#else
// compute gl_FragColor from material properties already computed
// and light sources
gl_FragColor = ... ;
#endif
}
Effects should test /sim/rendering/rembrandt/enabled in their predicate

Re: [Flightgear-devel] Ideas for terrain shader structure in 3.0
I'll certainly do what I can to help this one along. However, I'm not clear how this all ties in with the Rembrandt project. Are we in danger of having to tear it all down and starting over? I think it's fairly easy to unify shaders applied to geometry (models + terrain). Currently a Rembrandt shader computes material properties and then delegates the last step to an helper function : gbuffer_encode (https://gitorious.org/fg/fgdata/blobs/master/Shaders/gbuffer-encode.frag) We can imagine that this function (renamed to reflect more generality) could compute the final fragment color from material properties already computed and light source informations when used in the classical renderer. Different BRDF or lighting models are possible because Rembrandt has already the concept of material ID, allowing, for instance, to have water reflecting light differently than other kind of materials. This helper function will be chosen at run time using effect predicates and the link functionality of glsl programs. Sort of DLLs applied to shaders.

Rembrandt can't use a scheme where the depth buffer is cleared in between because it rely on it to compute positions. But it exhibits depth buffer precision problems too, especially when computing lights (if the light volume is too tight, it can miss to intersect the terrain).

Re: [Flightgear-devel] Rendering passes question
this could be unified with the classical renderer. What do you think about that ? I would probably give more of the range to the far camera e.g., [0.1..1.0]. This would probably work best with a floating point depth buffer, but if you do that, you might be able to go back to using only one pass. http://outerra.blogspot.fr/2012/06/couple-of-opengl-notes.html has some interesting insights into the various approaches.

Re: [Flightgear-devel] Rendering passes question
So, was there a reason we texture and fog during the first pass and should I see any unexpected side effects, or can I simply use the trivial shaders and get my 12% framerate? The main reason to render textures at this stage is that textures with transparency do change the fragments that are rendered. Calculating the fog color seems wrong, but I don't have the sources in front of me and gitorious is acting up. For instance, drawing the bridges without textures will show a wall instead of the suspension chain, the strands and the iron structure. I had the same problem rendering to the shadow map. So you won't see a boat behind through the structure or between the strands if you don't render the alpha-tested transparency embedded inside textures.

[Flightgear-devel] Rembrandt landing lights visible in MP or AI
Hi All, several aircraft have now landing lights in Rembrandt (DR400-jsbsim from PAF, c172p, Hurricane, ...). But not all are visible when seen as MP or AI models. With some changes and the help of Clément, we managed to have that : http://frbouvi.free.fr/flightsim/fgfs-rembrandt-dr400-multiplay.jpg To achieve that, the landing light animation was tight to the multiplayer properties (/sim/multiplay/generic/float[5] and /sim/multiplay/generic/int[11]) in order to show up in other's window. I tried the same with the c172p but unfortunately, I only see my own light. I presume the switch is not set to drive these properties. It would be cool if we could see other's light in MP.

Well since I still get a black screen after iconizing,
I dropped in some debug output in

{
if ((last_w != w)(last_h != h)) {
printf(Resize from %f,%f to %f,%f\n,
last_w, last_h,
w, h );
last_w = w;
last_h = h;
}
if (w -- 1.0 h == 1.0)
return;
etc
and re-compiled. Just to see what value it was when
I iconized...
and ?

Still get the lime green haze at certain angles -

Re: [Flightgear-devel] Rembrandt - ATI Radeo HD 2600 XT - Ubuntu 10.04
And none of this explains why Rembrandt CRASHES the Radeon HD 7770 - it stops working, and goes into auto-recovery - in my Windows 7 64-bit box. Without Rembrandt the fps there is 60... I bought myself a HD7750. The only issue I have under win7 64bit is that the fgfs window goes black if I minimize it. First investigation is that OSG open another context and reallocate all the resources already opened for the displayed window and exhaust memory, switching to pbuffers that are not supported by Rembrandt.

Individual buildings aren't instantiations of a small number of objects, as the random vegetation is.

There is an OpenGL feature that is available in OSG : you can instantiate the same geometry multiple times. You prepare the geometry once and when adding the primitive set (IIRC) you specify an optional number of instances. The vertex shader is call the number of instance specified times with a predefined uniform gl_InstanceID set from 1 to n. Of course, as you don't want your geometry draw n times at the same place, you have to compute the placement of objects inside the vertex shader using gl_InstanceID. Either you compute placement with an algorithm inside the shader, or you provide a matrix array uniform that you can index with gl_InstanceID. see http://www.opengl.org/wiki/Vertex_Specification#Instancing for a less nebulous explanation ;) Regards, -Fred -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Hi Thorsten, Quick question to Stuart: Currently the conditionals for texture selection are done using /position/longitude-deg,... i.e. aircraft position. The actual tile position however is different from that by the visibility and an direction, which makes for some uncertainty. So, it'd be more consistent to place a condition on the position of the tile to be loaded rather than the aircraft - is that information exposed somewhere (or would it be difficult to do that)? I suspect that special keywords in the format of the material file and a change in the tile loader are required to do that.

One is a breaking change that model designer should be aware of : the rembrandt related properties have been moved to a dedicated branch to tidy things a bit. So we now have : /sim/rendering/rembrandt/enabled instead of /sim/rendering/rembrandt /sim/rendering/rembrandt/use-color-for-depth instead of /sim/rendering/use-color-for-depth Shadow properties are untouched. Aircraft in the base package have been updated. Operations are now described in an XML file : Effects/default-pipeline.xml and a new option --renderer= allow to specify another.

But when two techniques use the same number, they are merged. I don't know if it was intended but one effect can modify one of it's parent without rewriting the predicate, and can lead to problems when we need to reassign numbers Regards, -Fred -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

See Effects/buildings.eff I hope you added a comment saying that you rely on the numbering of some other technique. I see the maintenance nightmare coming very soon.

Re: [Flightgear-devel] Trouble compiling FG on Ubuntu 12.04 64
Hi Chris, Hi all! This is my first mail on this list, so please forgive me newbie-mistakes. :) I've posted this request for help on the forum and had no luck with it. No one answered. So, I'll try here. I hope I'm no bother... http://www.flightgear.org/forums/viewtopic.php?f=45t=16180 My problem: I've tried to update my fgfs with brisas script for Debian/Ubuntu, as I did for years now... Sometimes there are problems, and compilation aborts. Most of the time I'm able to fix them myself, but this time, I don't even know, what the problem is, or if it is a problem... In the attachment you'll find the complete output of the compilation of OSG, SIMGEAR and FGFS. I wasn't sure if only the output of FGFS would be enough. OSG and SG built fine, no errors. Only some mysterious warnings, that some lib couldn't be found, but didn't seem to be a problem. So, I suggest you skip to the lower end of the file (~line 1450) and look for FGFS-compilation. In essence the following lines appear and bring make to a halt, funnily it continues to build after that, and halt with some similar lines: `.text._ZN3osg13TemplateArrayINS_5Vec3fELNS_5Array4TypeE10ELi3ELi5126EED2Ev' referenced in section `.text._ZN3osg13TemplateArrayINS_5Vec3fELNS_5Array4TypeE10ELi3ELi5126EED1Ev[osg::TemplateArrayosg::Vec3f, (osg::Array::Type)10, 3, 5126::~TemplateArray()]' of /media/myfiles/software/games/FlightGear/git/install/simgear/lib/libsgtgdb.a(SGOceanTile.cxx.o): defined in discarded section `.text._ZN3osg13TemplateArrayINS_5Vec3fELNS_5Array4TypeE10ELi3ELi5126EED2Ev[_ZN3osg13TemplateArrayINS_5Vec3fELNS_5Array4TypeE10ELi3ELi5126EED5Ev]' of /media/myfiles/software/games/FlightGear/git/install/simgear/lib/libsgtgdb.a(SGOceanTile.cxx.o) `.text._ZN3osg13TemplateArrayINS_5Vec2fELNS_5Array4TypeE9ELi2ELi5126EED2Ev' referenced in section `.text._ZN3osg13TemplateArrayINS_5Vec2fELNS_5Array4TypeE9ELi2ELi5126EED1Ev[osg::TemplateArrayosg::Vec2f, (osg::Array::Type)9, 2, 5126::~TemplateArray()]' of /media/myfiles/software/games/FlightGear/git/install/simgear/lib/libsgtgdb.a(SGOceanTile.cxx.o): defined in discarded section `.text._ZN3osg13TemplateArrayINS_5Vec2fELNS_5Array4TypeE9ELi2ELi5126EED2Ev[_ZN3osg13TemplateArrayINS_5Vec2fELNS_5Array4TypeE9ELi2ELi5126EED5Ev]' of /media/myfiles/software/games/FlightGear/git/install/simgear/lib/libsgtgdb.a(SGOceanTile.cxx.o) `.text._ZN3osg13TemplateArrayINS_5Vec4fELNS_5Array4TypeE11ELi4ELi5126EED2Ev' referenced in section `.text._ZN3osg13TemplateArrayINS_5Vec4fELNS_5Array4TypeE11ELi4ELi5126EED1Ev[osg::TemplateArrayosg::Vec4f, (osg::Array::Type)11, 4, 5126::~TemplateArray()]' of /media/myfiles/software/games/FlightGear/git/install/simgear/lib/libsgtgdb.a(SGOceanTile.cxx.o): defined in discarded section `.text._ZN3osg13TemplateArrayINS_5Vec4fELNS_5Array4TypeE11ELi4ELi5126EED2Ev[_ZN3osg13TemplateArrayINS_5Vec4fELNS_5Array4TypeE11ELi4ELi5126EED5Ev]' of /media/myfiles/software/games/FlightGear/git/install/simgear/lib/libsgtgdb.a(SGOceanTile.cxx.o) collect2: ld gab 1 als Ende-Status zurück make[2]: *** [utils/fgviewer/fgviewer] Fehler 1 make[1]: *** [utils/fgviewer/CMakeFiles/fgviewer.dir/all] Fehler 2 make[1]: *** Warte auf noch nicht beendete Prozesse...

I also don't know, what this option (make clean) is there for :) But I believe these were compiled with the same version of gcc - unless I have multiple versions installed, and the script uses multiply versions by design... Seems a bit unlikely to me, but I'm not sure at all. How can I find out? 'make clean' means deleting all generated files and redoing the whole build from scratch, not relying on a previous build. You may change compiler version if you enable OS updates.

[Flightgear-devel] Rembrandt on old cards
This is an update on my efforts to make rembrandt work on not so new GPU. I managed to make Rembrandt work on my NVidia 7600GT (on Debian Wheezy) with the following settings : --enable-rembrandt --prop:/sim/rendering/shadows/enabled=true --prop:/sim/rendering/shadows/num-cascades=1 --prop:/sim/rendering/shadows/cascade-far-m=50 --prop:/sim/rendering/shadows/map-size=2048 --prop:/sim/rendering/shadows/filtering=2 (or 1 for no filtering) --prop:/sim/rendering/use-color-for-depth=true Last one is new and only work at startup. There is only one cascade possible for the moment. Another value will lead to shader errors. The shadow map distance can be changed at runtime. 5 is best for cockpit view. 50 for outside view of the plane, 500 for the near terminals, or any other value you prefer. Filtering 2 is also available. I realize that all these cryptic options are not user friendly to casual users, so I am open to suggestions for improving the friendliness of these settings.
