Hi,
Someone sent me a link to the post below, I am the author of the code
in question.
re: Cloning of the IDs, I think this is spec compliant. The spec (the
doc you pointed two) specifies that the init function is called once
per renderer instance (or renderer thread), not once per shader
instance. In order to use per-shader initialization DSO authors will
normally add an additional DSO which lets them init a new invocation of
the DSO. There are a couple of example online of using this technique.
So basically you build a per-shader instance init on top of SL which
might end up looking like...
int callid = init_myshadeop("somestuff","otherstuff");
...
Cs = myshadeop(callid,P,,N,"whatever data");
...
shutdown_myshadeop(callid)
It might not be pretty, but then there is alot about RiSpec that
isn't pretty.
I'll see if there is anything we can do about the pointer conversion
issue.
I noticed that people seemed to be suggesting keeping a patch local
to debian, is this the normal way of doing things? Is there a policy of
pushing bugs and/or patches upstream to the originating project?
Cheers
Tristan Colgate
