Re: [osg-users] IVE Maximum File Size?
Hi John, I don't know of a reason why the .ive format should be size limited, everything is allocated dynamically on demand by the plugin. I haven't seen reports from the community w.r.t size issues with ive either, your experience is the first I've seen pop up. To investigate further try the sequences: 1) Write large model to .ive to result in a file exceed 1GB 2) Write same model to .osg 3) Load model into osgviewer to confirm that issue exists for this model. 4) Load model into osgviewer to confirm that issue does not happen. 5) use osgconv to convert the .ive model to second .osg file 6) Load .ive - .osg version of model into osgviewer, does it behave the same as the original .osg file, or the .ive? 7) Use a diff tool to compare the original .osg and the .ive-.osg version so see if anything has been lost in translation. Hopefully the above will give us a bit more information about the nature of the problem. Robert.

Re: [osg-users] [osgOcean] Shader again.
Hi Bawenang, You should need to use osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR. I'm not familiar with Delta3D but last time I heard about the osgOcean actor that was generated for it, it was using osgOcean 1.0. The version in the trunk now contains quite a few changes. The glare RTT camera simply takes the view and projection matrices from the main camera, so it shouldn't be behave any differently from your main camera. The glare is then rendered as a post render in a full screen quad. You can see an example of how to include additional elements into the scene in the OceanExample exe, take a look at the terrain and examine the shader that is attached to it. The shader shows you how to deal with the glare passes. Note: the version in the trunk is best for this. Regards, Kim.

Hi, could you explain what the texgen is for? You could also try osg::TexEnv::DECAL instead of BLEND. This should make the bottom texture appear in all transparent regions.

Re: [osg-users] rendering subset/subcamera views
Joel Skelton writes: Hi, I'm looking for alternate ideas on how to achieve a particular result. I've figured out a couple of ways to do it but each has issues. What I'd like to end up with is a scenegraph that renders something that is sort of like a web page with a 3D rendering inset into the middle of the page. Sort of like this: Code: +-+ pseudo-scenegraph | My Cow Page Title | | on white background | paper-camera | +---+ | /\ | | | |/ \ | |3D osg | | /\ | | | | / \ | | chrome cow | | /\ | | | |text nodes group \ | | rotating| | 3D-camera | | | | \ | +---+ | \ | |cow-group | More text on white | +-+ (ugh, my bad ascii art in the code block has every 2nd space char drawn as diamond in the preview. I hope its just my machine and everyone else can see this okay) So the paper of the web page would always be rendered through an ortho camera and you could zoom in and out which would change the onscreen size of the text on the page _as well as_ the size of the inset 3D view. The 3D view itself would behave like a regular OSG 3D perspective view which I could roam, zoom, and rotate just like a regular OSG View. As a final constraint, I'd like to be able to print this out at very high resolutions in a way similar to what is demonstrated in the osgposter example. So far I've figured two ways to do this: 1. The first would be by insetting one osg::View on top of another osg::View inside an osg::Viewer. The problem I have with this is that it wouldn't all be one scenegraph and I'd have to track the scaling of the paper view and use that to adjust the onscreen size of the 3D view. It would also be a chore to do hardcopy printing as demonstrated in the osgposter example, but not impossible. 2. The second idea is to prerender the 3D subview to a texture and apply that to a quad that is in the group under the paper camera. This seems like a mostly good idea except that if I wanted to print high resolution hardcopy then I would have to support tiled textures for the 3D view's textured quad and while not horribly difficult it would add a complexity to it all that I hope to avoid I hope I'm just missing some sort of obvious features of OSG like a subset view node or some such. In fact, if it turns out to be too obvious and simple then I'll punish myself for my own cluelessness by having my wife, a talented cartoon artist, draw an embarrassing picture of me in a tutu and I'll post it here. Thank you! Cheers, Joel I'm not sure about the printing part, but for those heterogeneous kind of scenes, maybe you can try the CompositeViewer, so it's more straightforward to have one viewer and several scenes inside it. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Texture Problem with AT Radeon Mobility!!!!
Hi Nectarios! We recently debug an osg application that have an issue with textures only in ATI cars. Our problem is that we render the same texture for different geometries and some of them have a texture matrix applied. We debugged our application with gDEBugger and notice that the mipmaps are not recomputed after apply the texture matrix. This old midmaps produce some errors in visualization. To disable hardware mid map generation you can set setUseHardwareMipMapGeneration(false) in your textures. This works fine in our application. You can use gDEBugger to show your texture mipmaps and detect if the error is there. Cheers, Maria.

Re: [osg-users] Render to texture for IPhone
Hi, Tang Camera frame texture is likely to be not power of two size. Osg by default resize textures to be power of two size, this can take a lot of time each frame in your case. You can disable resizing by calling setResizeNonPowerOfTwoHint(false) on your texture. Also use linear filtering as setFilter(osg::Texture2D::MIN_FILTER, osg::Texture2D::LINEAR) setFilter(osg::Texture2D::MAG_FILTER, osg::Texture2D::LINEAR) to disable mipmap generation. If you currently use filters with mipmaps, osg will re-generate mipmaps on texture change, which will reduce fps.

[osg-users] Getting height data of a terrain(flt file)
Hello Everyone, im using .flt files to load terrain. i loaded a sample terrain from the OSG data.(Joedirt.flt). i was wondering if there is a way to obtain the heightfield/heightmap for the terrain? i googled for .flt file format. i could not get any information on it. Could ot be a closed format? Could anyone please suggest how i could obtain the height data?

Re: [osg-users] Reading OSG images from streams?
Hi Eric, The functions are virtual, so it is up to each loader to override it and implement the functionality. Most of the image loaders should support reading from streams. I have been using this feature for a long time now and it works really well.

[osg-users] controlling osg::Cone pivot point...
Hi, i want to create some cone shapes in different part of my scene. and i want them rotate according to incoming orientation data on their translated places. But when i added my scene a simple osg::Cone with a radius 10 and height 100 at (0,0,0) that cone is drawn with tip at upper and base at bottom side around (0,0,0). (0,0,0) point is i think is at the weight center of that cone. What i need is to put tip of that cone at (0,0,0) (or to any point on the scene) and rotate base part according to orientation data.. How can i control the pivot point of that cone shap? Thx in advance.. :) ... Thank you!

Re: [osg-users] More than one ClipNode and ClipPlane
Hi Andrea, Positional state like clip planes are handled in a special way by the OSG as they have to be assigned a particular modelview matrix to position them correctly, and this means that you can't arbitarily state sort them and have any modelview matrix current when they are applied. The solves this problem by using a positional state node, and in the case of clip planes its the osg::ClipNode. The OSG also limits the setting of cliplanes so that a one clip plane can only be in one place at one time, and in OpenGL terms this means clip plane 0 can only be set once per rendering stage. OpenGL supports multiple clip planes, 6 being the minimum that OpenGL drivers have to support, so the OSG allows also allows you to assign each one of these clip planes at the same time - you just can't reuse the same GL clip plane index more than once. In you case it sounds like you are using multiple clip nodes and multiple clip planes which is perfectly safe usage, but the mistake is in not assigning a different clip plane number to each of the clip planes so they don't overlap in usage. Another important thing is that the ClipNode positions the (gl/osg::)ClipPlane while you'll need enable the appropropriate GL_CLIPPLANEi mode on the subgraphs that you want the clip plane to take effect.

I use two different clipnode in the scene, each relating to a different 3D object such as a cube and a cylinder. I created the first clipnode (CN_A) and I've associated with the tree of the cylinder, and the other clipnode (CN_B) the structure of the cube. Then I created a plane and a clipplane for each clipnode like this : ... // cylinder : osg::ClipNode* cnCylinder=new osg::ClipNode(); cnCylinder-addChild(cylinderModel); groupCylynder-addChild(cnCylinder); clipPlaneForCylinder=new osg::ClipPlane(); planeForCylinder=new osg::Plane(NormalCylinder,CenterCylinder); clipPlaneForCylinder-setClipPlane(planeForCylinder); cnCylinder-addClipPlane(clipPlaneForCylinder); cnCylinder-setCullingActive(false); . // ... cube osg::ClipNode* cnCube=new osg::ClipNode(); cnCube-addChild(cubeModel); groupCube-addChild(cnCube); clipPlaneForCube=new osg::ClipPlane(); planeForCube=new osg::Plane(NormalCube,CenterCube); clipPlaneForCube-setClipPlane(planeForCube); cnCube-addClipPlane(clipPlaneForCube); cnCube-setCullingActive(false); My application allows me to move each plane (in a separate way) in order to see how 3D model is cutted. BUT If i work with only one model and clipnode, it works correctly. If i use two models and two clipnodes i see only one cut effect on a 3D model and the other 3D model completely disappears. I.e. : If i apply clipnodes simultaneosly on CUBE and CYLINDER, i see the CUBE cutted and don't see CYLINDER. When i disable clipnode on CUBE, suddenly i see again the CUBE with the CUT effect. Again, if i apply clipnode on CYLINDER, i don't see anything. So , my question is : Is it possible to use more than one clipnode? Thank you!

[osg-users] [osgOcean] OceanExample - MakeTransform - Much different results with different boat model
Hi, I need help understanding what may be at play here... With the testCollision option to secure a boat for myself on the ocean, I promptly used a different boat I got from a collada dae file (a wooden dory from google sketchup 3dwarehouse), and ignored the one coming with the example because it was white and devoid of interesting texture. Iwas surprised to see my boat (finally when I figured out where it was) merrily bouncy along... not on the ocean surface, mind you... but moving up and down what would look like 20 feet in the air. So... please help me understand what I will have to watch out for using different models... and how to allow for and correct for these differences? I tried changing the scale returned from GetOceanSurfaceHeightAt(), and to no avail... then I tried just using 0 in the makeTranslate just to shut it up... and was surprised when it just ignored me and kept bobbing up and down in the air. I guess something else is responsible for positioning the boat on the surface? And NOT the node update visitor boatPositionCallback? search google's 3d warehouse for A wooden rowboat complete with oars, oar holders, beverage cabinet, and seats I would like to know how to get this boat out of the air, and into the water. It seems so strange. Thank you! Then... I'd like to keep water out of my boat... but first things first! ...Seeking UNDERStanding in an UnderWaterWorld Cheers, tim -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=37232#37232 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [osgOcean] Shader again.
Thanks for the reply. Well I know I shouldn't and I wouldn't if I don't have this artefact of the tip of the ship was not culled. I noticed that you're replying as a guest, not a member of this forum, so I'm not sure that you can see all of my screenshots that I've put here. If not, then I'll give you an illustration. Imagine a quake clone game. You've got a part of the weapon's model visible at the bottom of the screen, near the HUD, that will also move along with your first person camera. Now, in my application, that weapon will be culled and won't be rendered perfectly, even invisible at times, based on that camera's (and model along with it) translation and rotation. Now if I disabled near / far computation, the screen turns blank because the glare shader is also enabled. If I disable both the near / far computation and the glare shader, the scene seemed normal and right. However there's another artefact. The above water fog isn't implemented correctly. Even when there are two objects with the same distance with the camera, one of them can be rendered as if it's inside a fog and one of them is not. As for the missing model if I enabled glare, I've found the answer. It seems like osgOcean hates targa. One of my model's textures is a targa image file and that's why it wasn't rendered. When I changed it to a jpg, it worked just fine. Maybe you should put this as a warning somewhere in the documentation or such. Thanks again.

Re: [osg-users] Getting height data of a terrain(flt file)
Hi Mukund, OpenFlight is quite complicated yes, but actually more well documented nowadays. However, if you want to extract a regular terrain height raster from an OpenFlight database, I would say the best solution is to write an OSG application that simply intersects vertically with the terrain at equal distances and puts the result in a raster that you write to disk. Also, this would of course be a general file format-agnostic solution.
