Re: [osg-users] GLSL shader problem: texture2D() multiplying with textureCube()

One more point to add onto the problem is that I guess the actual problem is that in the debugger I receive the message: Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..) Is there any way to actually working out what is causing this error, it only every occurs if i

Re: [osg-users] GLSL shader problem: texture2D() multiplying with textureCube()

Hi Jason, Yeah I had tried that combination too. I have just tried increasing the units of the uniforms to use 1 and 2 instead of 0 and 1 Code: unsigned int unit = 1; it actually seems to make the calculation "work", but the diffuse color now being black instead of the should be sampled tex

[osg-users] GLSL shader problem: texture2D() multiplying with textureCube()

Hi, I have a problem that I have got my mind stuck at working out what is going wrong. I have a simple vertex and fragment shader I am trying to test. which look as follows: vertex: Code: varying vec3 normal, eyeVec, reflectVec; void main() { gl_TexCoord[0] = gl_MultiTexCoord0; gl_Position

Re: [osg-users] NULL Options passed to readImageFile()

Running any of the debug programs through dependencywalker comes up with the error that MSVCP80D.DLL Error Opening File. The System cannot find the specified file ( 2). But the file can be located here: C:\WINDOWS\WinSxS\x86_Microsoft.VC80.DebugCRT_1fc8b3b9a1e18e3b_8.0.50727.42_x-ww_f75eb16c t

[osg-users] Rotation of Vectors

Hi, I understand the concept of matricies, Vectors and Points in 3d Space. I have learnt this at University. I have an issue trying to understand the concept of OpenSceneGraphs use of Quaternions and "attitude". I do not really get what Attitude is, I'm used to the concepts of Translate,Rotat

Re: [osg-users] NULL Options passed to readImageFile()

I've downloaded and run the Redistributable, tried DependecyWalker.exe OSG example debug versions are missing: MSVCP80D.dll MSVCR80D.dll and both the examples and my debug version of my program are missing: EFSADU.dll IESHIMS.sll WER.dll So obviously I need these DLL's. Are they just things I

Re: [osg-users] NULL Options passed to readImageFile()

I have realised that it works fine if i select release build in VS 2005. So I guess my problem technically must lie in the fact that I cannot get the debug binaries to work: openscenegraph-all-2.8.0-win32-x86-vc80sp1-Debug.tar.gz I uncompressed these in exactly the same way that I have the rele

[osg-users] NULL Options passed to readImageFile()

Hi, I have only just installed OSG and got everything configured and the demo programs running. I have been going through the tutorials on openscenegraph.org and I am currently stuck on the pyramid texture tutorial: http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials/Textures I
