Detailed Description

template<typename T>
class globjects::Uniform< T >

Wraps access to typed global GLSL variables.

The Uniform class wraps access to typed global GLSL variables (uniforms). These are stored in the OpenGL program objects itself.

Supported OpenGL uniform setters are wrapped via specialized template set implementations. Note that unsupported uniform types result in compile time errors due to the default implementation of set.

Simple usage of an Uniform:

Uniform<float> * u = new Uniform<float>("u_ratio");
u->set(1.618f);
program->addUniform(u);
