Constructor & Destructor Documentation

virtual vgui_accelerate::~vgui_accelerate ( ) [inline, virtual]

Destructor.

Definition at line 40 of file vgui_accelerate.h.

vgui_accelerate::vgui_accelerate ( ) [inline, protected]

Definition at line 69 of file vgui_accelerate.h.

Member Function Documentation

vgui_accelerate * vgui_accelerate::instance ( ) [static]

Singleton instance of this class.

Definition at line 26 of file vgui_accelerate.cxx.

void vgui_accelerate::register_accelerator	(	vgui_accelerate *	p,
		int	level
	)		`[static]`

If level is higher than current level, then change to given accelerator.

Definition at line 32 of file vgui_accelerate.cxx.

bool vgui_accelerate::vgui_choose_cache_format	(	GLenum *	format,
		GLenum *	type
	)		`[virtual]`

Set the OpenGL cache format.

If you pass stuff to vgui_glDrawPixels, and the format and type are what you got from an earlier call to this baby, then it might go faster.

Reimplemented in vgui_accelerate_x11.

Definition at line 60 of file vgui_accelerate.cxx.

bool vgui_accelerate::vgui_copy_aux_to_back ( ) [virtual]

For X11/Mesa - copy auxiliary buffer to back buffer.

This function is used in X11/Mesa to speed up overlay emulation. It returns false to indicate to overlay_biscuit that a default emulation must be used.

Reimplemented in vgui_accelerate_x11.

Definition at line 78 of file vgui_accelerate.cxx.

bool vgui_accelerate::vgui_copy_back_to_aux ( ) [virtual]

For X11/Mesa - copy back buffer to auxiliary buffer.

This function is used in X11/Mesa to speed up overlay emulation. It returns false to indicate to overlay_biscuit that a default emulation must be used.

Reimplemented in vgui_accelerate_x11.

Definition at line 73 of file vgui_accelerate.cxx.

bool vgui_accelerate::vgui_glClear ( GLbitfield mask ) [virtual]

OpenGL clearing.

Reimplemented in vgui_accelerate_x11.

Definition at line 44 of file vgui_accelerate.cxx.
