Hi,
i thought i could use the buildin variabled to save some uniforms. But i did'nt
realize that they were limited.
Well..
i tried to use uniform arrays but with very little sucess:
I create my Uniform:
ref_ptr<Uniform> matrixArrayUniform = new
Uniform(Uniform::FLOAT_MAT4,"matrices",10);
stateSet->addUniform(matrixArrayUniform.get());
later i add 10 matrices:
for (int i = 0; i < 10; i++) {
matrixArrayUniform->setElement(i, texMat->getMatrix());
}
i defined the uniform within my fragment shader:
"uniform mat4 matrices[10];"
and tried to access a matrix via matrices[2] for example but with no luck.
If i use no arrays and limit the size of the uniform to one element everything
works just as expected.
Must i use something other than osg::Uniform::FLOAT_MAT4?
Greetings,
Johannes
