Re: [Opensg-users] uniform parameter [slightly off topic]

Hi Antonio,

you can get the parameters from the SHLChunk.


Andreas

MFShaderParameterPtr &parameters = _shl->getParameters();
for(UInt32 i = 0; i < parameters.size(); ++i)
{
    ShaderParameterPtr parameter = parameters[i];
    switch(parameter->getTypeId())
    {
        case ShaderParameter::SHPTypeInt:
        {

ShaderParameterIntPtr p =ShaderParameterIntPtr::dcast(parameter);

            Int32 v = p->getValue();
        }
        case ShaderParameter::SHPTypeVec2f:
        case ShaderParameter::SHPTypeVec3f:
        case ShaderParameter::SHPTypeVec4f:
        case ShaderParameter::SHPTypeMatrix:
        ....
    }
}

Hi,

I'd like to query the uniform parameters

from a shader (OpenGL 2.0) in order to queryautomatically all uniform parameters a shaderhas to offer.

The SHLChunk class provides methods to
set and get uniform parameters, but there's

no way to get a listing of all parameters(including their types). Is there another

toolkit that lets me query this information?
OpenGL directly, perhaps?

Regards,

  Toni
