bool glxGraphicsBuffer::begin_frame ( FrameMode  mode,
Thread *  current_thread 
) [virtual]

This function will be called within the draw thread before beginning rendering for a given frame.

It should do whatever setup is required, and return true if the frame should be rendered, or false if it should be skipped.

Reimplemented from GraphicsOutput.

Definition at line 71 of file glxGraphicsBuffer.cxx.

References GraphicsOutput::begin_frame_spam(), GraphicsOutput::clear_cube_map_selection(), and GraphicsOutput::get_fb_properties().

void glxGraphicsBuffer::close_buffer ( ) [protected, virtual]

Closes the buffer right now.

Called from the window thread.

Reimplemented from GraphicsBuffer.

Definition at line 139 of file glxGraphicsBuffer.cxx.

void glxGraphicsBuffer::end_frame ( FrameMode  mode,
Thread *  current_thread 
) [virtual]

This function will be called within the draw thread after rendering is completed for a given frame.

It should do whatever finalization is required.

Reimplemented from GraphicsOutput.

bool glxGraphicsBuffer::open_buffer ( ) [protected, virtual]

Opens the buffer right now.

Called from the window thread. Returns true if the buffer is successfully opened, or false if there was a problem.
