Detailed Description

Manage GPU programs in the pipeline.

In OpenGL many parts of pipeline are dynamically programmable by user. This module wraps all parts of OpenGL that are directly responsible for manipulating user programs.

Function Documentation

void glpp::bind_to	(	GLuint	point,
		uniform_block *	pblock,
		buffer *	pbuffer
	)		throw (std::invalid_argument)

Bind a uniform_block and a uniform buffer object to common point.

Parameters

point	The point to bind both objects. If something else is binded there, it will be overwritten
pblock	Pointer to uniform_block that will binded with the uniform buffer object.
pbuffer	Pointer to uniform buffer object. This object will be checked that it is of type() uniform.

Exceptions

std::invalid_argument

If the pbuffer is not of uniform type.

shared_shader_t glpp::open_shader_file	(	shader_type	type,
		const std::string	fname
	)

Create shader object from in-file source code.

Parameters

type	Type of the shader to create
fname	Filename where GLSL source code resides

Exceptions

std::invalid_argument

If the file cannot be accessed.

open_shader_files()

shared_shader_t glpp::open_shader_files	(	shader_type	type,
		std::initializer_list< const std::string >	fnames
	)

Create shader object from multiple GLSL source files.

Parameters

type	Type of the shader to create
fnames	Filenames where GLSL source code resides. The order of file is important, as in the same order the source code will be concatenated.

Exceptions

std::invalid_argument

If any of the files cannot be accessed.
