Virtual Method

CoglOnscreenswap_region

Declaration [src]

void
swap_region (
  CoglOnscreen* onscreen,
  const MtkRegion* region,
  CoglFrameInfo* info,
  gpointer user_data
)

Description [src]

Swaps a region of the back buffer being rendered too, to the front for display.

This function also implicitly discards the contents of the color, depth and stencil buffers as if cogl_framebuffer_discard_buffers() were used. The significance of the discard is that you should not expect to be able to start a new frame that incrementally builds on the contents of the previous frame.
