fastuidraw::gl::SamplerInitializer Class Reference

Class to intialize the binding points of samplers. If the uniform is an array, the first element will be given the specified binding point and successive elements in the array will be given successive binding points. More...

Constructor & Destructor Documentation

SamplerInitializer()

fastuidraw::gl::SamplerInitializer::SamplerInitializer ( c_string  uniform_name, int  binding_point  )

inline

Ctor.

Parameters

uniform_name	name of uniform sampler2D in GLSL to initialize
binding_point	binding point to initialize the uniform to; If the uniform is an array, the first element will be given the specified binding point and successive elements in the array will be given successive binding points.

Definition at line 1633 of file gl_program.hpp.

Member Function Documentation

init_uniform()

virtual void fastuidraw::gl::SamplerInitializer::init_uniform ( GLuint  program, Program::shader_variable_info  info, unsigned int  array_index, bool  program_bound  ) const

protectedvirtual

To be implemented by a derived class to make the GL call to initialize a uniform in a GLSL shader.

Parameters

program	GL program
info	information on uniform (name, type, location, etc)
array_index	index into GLSL uniform if it is an array
program_bound	true if and only if the program named by program is bound (via glUseProgram). If the program is not bound, then one SHOULD not bind the program and instead use the GL API points to set values of the uniform(s) that do not rely on having the program bound. One can also safely assume that those API points are supported in the case it is not bound (in particular the function family ProgramUniform() can be safely used).

Implements fastuidraw::gl::UniformInitalizerBase.
