Overview
|
|
|
|
|
|
|
|
|
|
Mesa is often used as a client library with no integration with
|
|
|
|
|
the computer's window system (an X server, for example). And since
|
|
|
|
|
Mesa does not have an event loop nor window system callbacks, it
|
|
|
|
|
cannot properly respond to window system events. In particular,
|
|
|
|
|
Mesa cannot automatically detect when a window has been resized.
|
|
|
|
|
|
|
|
|
|
Mesa's glViewport command queries the current window size and updates
|
|
|
|
|
its internal data structors accordingly. This normally works fine
|
2012-08-17 07:57:59 -06:00
|
|
|
since most applications call glViewport in response to window size
|

|
|
|
changes.
|
|
|
|
|
|
|
|
|
|
In some situations, however, the application may not call glViewport
|
|
|
|
|
when a window size changes but would still like Mesa to adjust to
|
|
|
|
|
the new window size. This extension exports a new function to solve
|
|
|
|
|
this problem.

|
The glResizeBuffersMESA command may be called when the client
|
|
|
|
|
determines that a window has been resized. Calling
|
|
|
|
|
glResizeBuffersMESA causes Mesa to query the current window size
|
|
|
|
|
and adjust its internal data structures. This may include
|
|
|
|
|
reallocating depth, stencil, alpha and accumulation buffers.
