[Mesa3d-dev] on highly dynamic textures (ie: movies and similar)

[winterlion <win...@fs...>]

Is there a method for either making small updates to an OpenGL texture or
making a block of videomemory writable by a program?

on small updates to a texture:
actually AFAIK this is possible - but all tests I've done so far
failed..  mind you I couldn't find documentation so...

Primary uses:
	Movies on a texture
	Applications on an X-emu on a texture

Now this might be a nonissue (ie: like I said I have a lack of
documentation :) or something not applicable to the developer side...  but
while applications on a texture can be relatively efficient, playing a
movie when every frame has to be uploaded is a little costly.
(okay, with a 3D accel such as the 3dfx/banshee I have it still happens)

Thanks in advance for any ideas :)
(and please tell me if I'm out to lunch - or if even anyone's getting any
of my message..  My last one on 3dfx-accel using mesa on glide2x without X 
didn't get an answer....)

G'day, eh? :)

PS: one would think there exists a formal extension to describe such a
circumstance :)
