GLX is an X protocol extension that provides access to OpenGL rendering. OpenGL commands are encapsulated in X protocol stream. Thus, one can run their OpenGL applicaion on a machine that does not even have a video card (if they manage to boot it), by just remotely connecting to it and launching the CLX+GLX application, which in turn will connect to the specified X server. Needless to say, the server should support the GLX extension.
Here you can get a diff against CLX package
available in CLiki (version 0.6 at
the moment). To apply the patch, go to the folder where your CLX is, and
patch < path/to/glx.diff
When you have it loaded, do this to try out the super-duper
CL-USER> (in-package :gl-test)
GL-TEST> (test 'anim :host "" :display 0)
The code is in a very early stage of developement (actually it is more like a proof-of-concept implementation to check if it can be done at all) so I suggest you use nested X server for experimenting. If you have any questions, suggestions, patches or anything else to offer, contact me by email.
There's also some media I have created to show off: a screenshot and a movie and another movie.
now work. The sequence argument must be of required length and contain elements of specified type and can be one of:(define-rendering-command tex-env-fv 112 (target card32) (pname card32) (param (list float32 (ecase pname (#.+texture-env-mode+ 1) (#.+texture-env-color+ 4)))))
example work just fine (except the skewed geometries, which I think are due to a transcription error).(test 'gears*)
