Detailed Description

This class represents a Texture object in GPU memory.

Constructor & Destructor Documentation

LUMINOUS_API Luminous::TextureGL::TextureGL ( StateGL & state )

Constructor.

Parameters

state OpenGL state

LUMINOUS_API Luminous::TextureGL::TextureGL ( TextureGL && t )

Move constructor.

Parameters

t	texture object to move

void Luminous::TextureGL::bind ( int textureUnit )

inline

Bind the texture to the given texture unit.

Parameters

textureUnit texture unit to bind to

QRegion & Luminous::TextureGL::dirtyRegion2D ( )

inline

Get the dirty region of the texture.

The dirty region keeps track of regions in the texture that must be re-uploaded.

LUMINOUS_API TextureGL& Luminous::TextureGL::operator= ( TextureGL && t )

Move assignment operator.

Parameters

t	texture object to move

LUMINOUS_API void Luminous::TextureGL::upload	(	const Texture &	texture,
		int	textureUnit,
		bool	forceBind
	)

Upload texture data from CPU object.

Parameters

texture	texture to upload from
textureUnit	Texture unit, starting from 0
forceBind	force binding of texture even if it is already active
