Member Function Documentation

vgui_accelerate * vgui_accelerate::instance (   )  [static, inherited]

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, inherited]

If level is higher than current level, then change to given accelerator. Definition at line 32 of file vgui_accelerate.cxx.

virtual bool vgui_accelerate_x11::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 from vgui_accelerate.

virtual bool vgui_accelerate_x11::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 from vgui_accelerate.

virtual bool vgui_accelerate_x11::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 from vgui_accelerate.

virtual bool vgui_accelerate_x11::vgui_glClear (  GLbitfield  mask  )  [virtual]

OpenGL clearing. Reimplemented from vgui_accelerate.

virtual bool vgui_accelerate_x11::vgui_glDrawPixels (  GLsizei  width, GLsizei  height, GLenum  format, GLenum  type, const GLvoid *  pixels )  [virtual]

Fast-as-we-can version of drawpixels. Reimplemented from vgui_accelerate.
