The setup had been lost at some stage, thus shadows were always directly
under the entity. Unlike the original quake shadow code, the vector is
correctly transformed into the entity's space.
I finally found the cause of Despair's gl shadows non-rendering+segfault...
the shadow code expected triangle fans and strips but was getting simple
triangles. Oops.
Nothing in the main program currently uses Key_Progs_Init, so the object
file wasn't getting pulled into the link. However, it's quite necessary for
the client console plugin :/
That is, the descriptors loaded from the progs file. Some compilers (eg,
fteqcc :P) strip builtin names from the progs, which makes debugging
difficult.
LordHavoc had made lighting positive for sw32, but I had done something in
the plugin code that broke that (probably something to do with the
colormap loading). Going back to id's original code fixes the issue.
This reverts commit e170f4ee75.
It turns out I messed up something in the patch. I noticed the problem
while playing digs04.bsp: many sub-model surfaces, particularly those with
animated textures, were not being transformed correctly. As this patch did
not make a large performance difference, it's probably better to just
revert it. I might revisit it later.
Since the backtile is loaded into a scrap and used as a subtexture, we
can't use GL's texture wrapping, thus do the wrapping ourselves. There are
some minor issues with the wrong part of the scrap being drawn: need to
investigate where the bug is (vrect, make_quad, etc).
Rather than checking the raw edict count in the entities file against the
progs' max_edicts, check the allocated entity's number. This allows loading
of sophisticated maps (eg, digs04) that prune many of their entities.
In the end, it turns out this is the correct fix for the gl seg on
overkill, because build_skin will correctly use the fully setup player skin
if the glskin doesn't have a texture associated with it.
It turns out glsl, sw and sw32 weren't getting any benefit from R_CullBox
because the frustum wasn't setup :P. Get another 8% out of bigass1
(174->184fps). bigass1 now runs 2x as fast as it did before I started this
optimisation run :)
This severely reduces the calles to BindTexture, and more importantly,
glUseProgram, EnableVertexAttribArray etc. The biggest changes are:
o icons and text are all in the one giant texture
o icons and text are mixed in the one queue
This gave ~9% speedup for bigass1 (159->174fps).
It seems recent(?) 64-bit strcpy implementations of strcpy don't work
properly for overlapping regions even when moving down. Quite the
surprise, as I thought that would always work. *shrug*
I didn't like the way client/server code was poking around at the
implementation. Instead, provide a couple of accessor functions for the
same information.
