Detailed Description

Represents an openGL uniform value.

After a program has been linked, you can create Uniform objects to let you set the uniforms that your shaders use.

Be careful not to call the set() functions unless the appropriate program is loaded into the current context.

Constructor & Destructor Documentation

Uniform()

juce::OpenGLShaderProgram::Uniform::Uniform	(	const OpenGLShaderProgram &	program,
		const char *	uniformName
	)

Initialises a uniform.

The program must have been successfully linked when this constructor is called.

uniformID

GLint juce::OpenGLShaderProgram::Uniform::uniformID

The uniform's ID number.

If the uniform couldn't be found, this value will be < 0.
