Member Function Documentation

int gk::GLRendertarget::attachTexture	(	const GLenum	target,
		const unsigned int	buffer,
		GLTexture2D *	texture,
		const int	level = 0
	)			[inherited]

associe une texture existante au framebuffer.

buffer = gk::COLOR0, etc. ou gk::DEPTH. toutes les textures doivent avoir les memes dimensions.

References gk::GLTexture::target().

const std::vector<GLenum>& gk::GLRendertarget::drawBuffers

(

)

const [inline, inherited]

renvoie les draw buffers opengl / textures attachees (cf. glDrawBuffers() et GL_COLOR_ATTACHMENT0, etc.).

    const std::vector<GLenum>& buffers= framebuffer->drawBuffers();
    glDrawbuffers((GLsizei) buffers.size(), &buffers.front());
