Hi most likely, it uses a texture rectangle instead of texture2d, it uses texture coords in pixels. Cheers. 10.10.2012, 16:46, "Peterakos" hay...@gmail.com:Hello.in the example  osgmultiplerenderingtargets, why are the texture coordinates initialized as:0,0tex_width, 

Re: [osg-users] Difference between osgFX and osgPPU

Hi They are completely different. osgFX have support for multipass rendering of geometry, osgPPU purpuse is to do postprocessing on camera output. Cheers.08.10.2012, 22:01, "Peterakos" hay...@gmail.com:Hello.Is there any difference between these 2 or are they different implementations for the same

Re: [osg-users] Memory issues when using uniform shader variables on Intel HD graphics

Hi What exactly makes memory usage increase? What if you attach shader without uniform, or without adding uniform to stateset? Try to add #version 110 directive as first line of your shaders, does it make any difference? I think you'd better send bugreport to intel, best if you can reproduce

Re: [osg-users] multipass transparency

Hi If you need to blend all visible layers - try to change order of passes, and set colormask to all false's (so first will be only color, second only depth). If you dont need depth from transparent geometry - you can get by with only first pass. If you need only closest single layer - you

Re: [osg-users] Normalmap with osgPPU

Hi osgppu drawing screen aligned quad with each pass, using texture data you've provided as input. It does not have access to your scene in any way except of mentioned textures.vertex shader process vertices of this quadnormals you are getting is normals of this quad (so they are all the same, and

Re: [osg-users] Help:why does renderbin affect the display of textures ?

Hi Seems like you are messing with opengl state, and osg dont know about it. You should either: a) when you draw something with pure gl - after you finished, return all state you modified to values being before you started drawing b) use osg::State interface members to let osg know what state

Re: [osg-users] How can I get the viewer's camera to 'ignore' a node's geometry?

Hi I believe this caused by small features culling (which is culling away objects which cover less space on screen than some pixel threshold). With compute near far enabled - when camera far enough objects on earth surface gets culled away, and as there are no objects on earth surface get's

Re: [osg-users] How can I get the viewer's camera to 'ignore' a node's geometry?

Hi You can set ComputeBoundingBoxCallback on a geometry to specify whatever bounds you want. In your case to ignore earth geometry bound you can set its bound to uninitialized bounding box, and it will not make any difference to near\far calculations. Note that this thing completely disable

Re: [osg-users] osg::PPU texel 0,0 in depthbuffer is wrong

Hi Check texture wrap mode, it can be set to clamp_to_border, with some border color. Does it work okay when sampling other texture areas? Dont know if it can cause problem, but texture(...) call returns vec4, and you are sampling single component texture. I believe it returns (depth, 0, 0, 1),

Re: [osg-users] How can I get the viewer's camera to 'ignore' a node's geometry?

ane closer and give you the z-buffer resolution you need in order to visualize surface features. In addition, you can decrease the Camera's near/far ratio; this will give you a little more near clip space if you still need it.Glenn Waldron / @glennwaldron On Fri, Oct 5, 2012 at 7:28 AM, Sergey Pol

Re: [osg-users] osg::PPU , Texture unit associated with depth buffer

Hi There are not only explicit texture bindings, but also implicit ones, which passed from units parents. If your unit added to other ppu units, it uses theirs output as input textures in order. There are also interfaces to bind other unit output to uniform IIRC setInputToUniform call Cheers.

Re: [osg-users] glslDevil

Hi. It used to be great tool at a time, but now is quite outdated, it would be great to see this project being developed further, as IIRC there are no crossplatform analogs with same functionality. Wish you best luck. Does anyone here on the list know any of the folks involved in the glslDevil
