Hey Daniel,thanks for your hint. Using your little trick, I was able to debug my fragment shader.
The working code looks like this: MFVec3f parameters = MFVec3f(); <- without specifying the field size!!! parameters.push_back(osg::Vec3f(0.8f, -0.2f, 0.2f)); parameters.push_back(osg::Vec3f(0.1f, 0.2f, 0.2f)); parameters.push_back(osg::Vec3f(-0.6f, 0.5f, 0.5f)); Cheers, Daniel Daniel Holz schrieb:
Hi Anne, Anne Braun wrote:Shader: #define NUMPOINTS 3 uniform vec3 vectors[3]; void main(void) { vec3 vector; ... for(int i = 0; i < NUMPOINTS; i++) { vector = vectors[i]; ...To be honest, I have no idea how to debug the shader to check whether the values are correct. But using with a single vector instead of a array it works?!A common way to debug shaders is to output values as fragment color. You could try something likegl_fragColor = vec4(vectors[0], 1.0);It would also be helpful to set the colors in your "vectors" array to, e.g., (1,0,0), (0,1,0) and (0,0,1).In this case you will see right away if the colors match your expectations.
