Re: [osg-users] integrating AntTweakBar GUI with OSG

Hi Anna, I have been trying for almost a week to get the AntTweakBar to work properly with OSG, without any success. I still don't get any text, and I get coloured rectangles instead. I need help :) Did you have the same problems with integrating AntTwakBar in your OSG application? Can anyone

[osg-users] dynamic cube map

Hi, I am trying to make a dynamic cube with osg. The idea is to render into a cube map the +X, -X, +Y, -Y, +Z and -Z view from the camera view point at each frame. Then the cube map is textured on a reflector surface (a plane) within a shader. I would like to see other objects (sphere, cube)

Hi Paul, Or better yet: gl_TexCoord[1] = texGen * gl_Vertex; There is a lot of overlap between the object plane equations and the texture matrix. Originally, the thinking behind the object plane equations was that you might only be concerned with s and t, so it was more efficient than

Re: [osg-users] TexGen OBJECT_LINEAR in shaders

Hi Paul, I've found the problem. So you confirm that the fixed function fragment stage will not do anything special when texgen is active, i.e. that it will only do: vec4 col = texture2D( tex, gl_TexCoord[1].st ); ? Seems this was not correct, I had to do a transformation: vec3 texCoord
