Member Function Documentation

void opentl::modelprojection::GLRenderer::drawObjects	(	const std::vector< boost::shared_ptr< opentl::core::State > > &	states,
		const std::vector< opentl::models::ObjModel * > &	objModels,
		int	camIdx,
		std::vector< int > &	linkIds,
		DrawMode	drawMode = DRAWFACES_NOLIGHTING,
		HiddenMode	hiddenMode = ALL,
		DrawBuffer	drawBuffer = SCREENBUF,
		opentl::core::cvdata::TextureGpu *	backgdTex = NULL,
		opentl::core::cvdata::TextureGpu *	outputTex = NULL
	)

Draw the stored object with the with the latest warp settings in the current OpenGL context in the selected mode.

Parameters:

	states	Vector of states.
	objModels	Vector of object models
	camIdx	Camera index.
	linkIds	Link indices: for each object, a single link, or the full shape (id = -1) can be rendered.
	drawMode	Can be one of the DrawMode constants.
	HiddenMode	Can be one of the HiddenMode constants.
	drawBuffer	Buffer to draw into.
	backgdTex	Option: Render onto an existing background texture.
	outputTex	Option: Render into an externally-provided output texture (only when FBO is used!).

void opentl::modelprojection::GLRenderer::drawObjectsIntoImage	(	const std::vector< boost::shared_ptr< opentl::core::State > > &	states,
		const std::vector< opentl::models::ObjModel * > &	objModels,
		int	camIdx,
		std::vector< int > &	linkIds,
		opentl::core::cvdata::Image &	dstImage,
		DrawMode	drawMode = DRAWFACES_NOLIGHTING,
		HiddenMode	hiddenMode = ALL,
		opentl::core::cvdata::TextureGpu *	backgdTex = NULL,
		bool	computeROI = false
	)

Same as drawObjects, but result is drawn into image. TRY TO AVOID THIS FUNCTION, IT'S SLOW!

Parameters:

	states	Vector of states.
	objModels	Vector of object models
	camIdx	Camera index.
	linkIds	Link indices: for each object, a single link, or the full shape (id = -1) can be rendered.
	dstImage	Destination image (must have the same size of camera camIdx).
	drawMode	Can be one of the DrawMode constants.
	HiddenMode	Can be one of the HiddenMode constants.
	backgdTex	Option: Render onto an existing background texture.
