[Opensg-users] How to set shader parameter to vec3 array?

[Anne Braun]

Hello everybody,

I'm trying to pass a vec3f array to my shader programm using the function:
shader->setUniformParameter(const char* name, const osg:MFVec3f &value)
On shader side I have the parameter: uniform vec3 vectors[NUMPOINTS]
Using a single vector
shader->setUniformParameter("vectors", osg::Vec3f(0.8f, -0.2f, 0.2f)); 
it works fine. But using a MFVec3f it doesn't work.

Can anybody help me using the MFVec3f?

Thanks and regards,
Anne
