Typically, each canvas instantiation has one
|
|
SurfaceProxyManager object, to handle their surfaces. Surfaces
|
|
itself are opaque objects, which encapsulate a framebuffer to
|
|
render upon, plus an optional (possibly accelerated) texture.

/** Create a surface proxy for a color buffer.
|
|
|
|
The whole idea is build around the concept that you create
|
|
some arbitrary buffer which contains the image data and
|
|
tell the texture manager about it. From there on you can
|
|
draw into this image using any kind of graphics api you
|
|
want. In the technical sense we allocate some space in
|
|
local videomemory or AGP memory which will be filled on
|
|
demand, which means if there exists any rendering
|
|
operation that needs to read from this memory location.
|
|
This method creates a logical hardware surface object
|
|
which uses the given color buffer as the image source.
|
|
Internally this texture may even be distributed to several
|
|
real hardware surfaces.
