Detailed Description

An OpenGL texture wrapper. It automatically takes care of all OpenGL texture handling issues and also provides access to the texture data.

Constructor & Destructor Documentation

Texture()

OpenGL::Texture::Texture	(	GLenum	glIntFormat,
		GLenum	glFormat,
		GLenum	glType,
		const Graphics::PixelFormat &	format
	)

Create a new texture with the specific internal format.

Parameters

glIntFormat	The internal format to use.
glFormat	The input format.
glType	The input type.
format	The format used for the texture input.
