Method
CoglOnscreenswap_region
Declaration [src]
void
cogl_onscreen_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.
