[Chromium-dev] seethrough SPU and documents

[Anthony S. <A....@cs...>]

I've been lurking on this list for a while - we've been using Chromium 
for a while for some demos and prototyping some systems for driving a CAVE.

Because of the experience of a student, I took a look at the online 
documentation. The online and CVS documentation for the seethrough 
example is out of date (the state tracker code was wrong, some code 
typos). I had a go at updating it and it almost works as advertised now.

First things first: in template/gen_template.py, the file 
templatespu_proto.py doesn't exist, so the generation scripts fails. 
That line needs deleting.

In the seethrough example, I fixed all the problems with changed data 
structures and code, but I can't get my quake3 to look like glassquake 
unless I force multitexturing to be off. I.E. in q3config.cfg, change:

  seta r_ext_multitexture "1"
to
  seta r_ext_multitexture "0"

I had a quick go at getting the multitexturing working, but someone who 
knows more about chromium could probably spot the problem straight away. 
Otherwise it works fine.

As I'm not registered as a developer on sourceforge, I put a revised 
version of the codegen.html here:

and code packages here:
