protectedvirtual

Implements osg::Texture.

◆ copyTexImage2D()

void osg::TextureRectangle::copyTexImage2D	(	State &	state,

	)

Copies pixels into a 2D texture image, as per glCopyTexImage2D.

Creates an OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width and height height. width and height must be a power of two.

◆ copyTexSubImage2D()

void osg::TextureRectangle::copyTexSubImage2D	(	State &	state,
