'''OpenGL extension SGIX.texture_multi_buffer
This module customises the behaviour of the
OpenGL.raw.GL.SGIX.texture_multi_buffer to provide a more
Python-friendly API
Overview (from thespec import
This extension provides an API for the application to specify that
the OpenGL should handle multiple textures in such a way that,
wherever possible, a texture definition or redefinition can occur
in parallel with rendering that uses a different texture.
The texture_object extension allows the simultaneous definition
of multiple textures; any texture that is not being used for
rendering can, in principle, have its definition or operations
in its definition (e.g. downloading to hardware) occur in parallel
with the use of another texture. This is true as long as all
redefinitions strictly follow any use of the previous definition.
Conceptually this is similar to frame buffer double-buffering,
except that the intent here is to simply provide a hint to the
OpenGL to promote such double-buffering if and wherever possible.
The effect of such a hint is to speed up operations without
affecting the result. The user on any particular system must be
knowledgable and prepared to accept any trade-offs which follow
from suchahint. import
GL_FASTEST in this context means that texture multi-buffering
is being used whenever possible to improve performance.
Generally, textures that are adjacent in a sequence of multiple
texture definitions have the greatest chance of being in
different buffers. The number of buffers available at any time
depends on various factors, such as the machine being used and
the textures' internal formats.
The official definition of this extension is available here:
