bc7858bb87 [model] Move parent pointer out of leaf/node struct 
The node struct was 72 bytes thus two cache line. Moving the pointer
into the brush model data block allows nodes to fit in a single cache
line (not that they're aligned yet, but that's next). It doesn't seem to
have made any difference to performance (at least in the vulkan
renderer), but it hasn't hurt, either, as the only place that needed the
parent pointer was R_MarkLeaves.

34dc7cf2df [models] Move brush data into its own struct 
This is a big step towards a cleaner api. The struct reference in
model_t really should be a pointer, but bsp submodel(?) loading messed
that up, though that's just a matter of taking more care in the loading
code. It seems sensible to make that a separate step.

bb6c6963d2 [model] Clean up the globals around model loading 
Covers only the generic load code (alias etc to follow), but this should
take care of a lot of issues in the future.

0f81432090 [model] Load bsp textures into vulkan 
The textures for an entire model are loaded into a single memory object
with shared between multiple images.

6e0cb7b917 [model] Isolate renderer specific texture data 
This cleans up texture_t and possibly even improves locality of
reference when running through texture chains (not profiled, and not
actually the goal).

9b53d7d4e2 [model] Remove empty brush model functions 
It seems better to check for a null pointer and just not call.

494f673def Fix a potential buffer overflow 
Highly unlikely to have that many sub models, but it does keep gcc
quiet.

4f58429137 Fix an unhealthy pile of gcc 8 warnings. 
While some of the warnings were merely annoying, some where actual bugs or
unearthed bugs in related code.

9d6954efb7 Fixup extended bsp when loading the file. 
It turns out the tools need the node conversions too, so doing it in
bspfile seems to be best as it is used by everything that reads a bsp file.

a4d95f3f53 Move Mod_FindClipDepth and recurse_clip_tree into clip_hull.c. 
Since the hull depth needs to be set for the hull to be useful, it makes
sense to move the code into the same place that allocates new hulls (to me,
anyway).

a12eb940f1 Remove the hard-coded bsp maximum depths. 
The depth limits in the gl and glsl renderers and in the trace code really
bothered me, but then the fix hit me: at load-time, recurse the trees
normally and record the depth in the appropriate place. The node stacks can
then be allocated as necessary (I chose to add a paranoia buffer of 2, but
I expect the maximum depth will rarely be used).

45c48a6215 Fix bsp2 loading. 
Just some problems with the handling of extended bsp29 files. I'm not
quite happy with the code, but it will do for now.

a37c5465e1 First step for BSP2 support. DOES NOT WORK! 
All of the nastiness is hidden in bspfile.c (including the old bsp29
specific data types). However, the conversions between bsp29 and bsp2 are
implemented but not yet hooked up properly. This commit just gets the data
structures in place and the obvious changes necessary to the rest of the
engine to get it to compile, plus a few obvious "make it work" changes.

69fb78278f Remove the redundant endian conversions from bsp loading. 
It's obvious that it's been a very long time since anybody's tried playing
QF on a big-endian machine: double converting data isn't good :/

QF still leaks about 3MB/run on demo1, but even 100 runs didn't show any
render issues.

b43d03a98b Let the render specific texture loader decide on sky texture loading. 
This is necessary to allow the glsl texture loader to process the sky
textures.

91e65b6c80 Rename mplane_t to plane_t and clean up the mess. 
I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.

any issues yet.

8831a109a4 Create and use mclipnode_t. 
I didn't realize this was a critical part of fitzquake's large map
support. This should fix the non-solid brush entities in Conflagrant
Rodent.

cd159e1cc1 Use LoadBSPMem to load brush models. 
Now that Mod_LoadBrushModel uses bspfile.[ch], the engine uses the same
code as the tools to work with bsp files.

99c0954b47 the big dso visibility patch :). Sure, we have to have unique names for static builds, but with controlled visibitly we should get faster program loads (although this isn't C++, so it's not as bad) and complex plugins are cleaner. 2007-03-10 12:00:59 +00:00

45d467d748 box tracing (instead of point). Currently disabled because it doesn't work right just yet. However, when it is working, it will let us do things like crouching, crawling, arbitrary sized objects (including players), etc. 2006-12-24 03:13:29 +00:00

Calculate radius for alias models as well as brush.
Culling is no longer optional on alias models (was only ever disabled for viewmodel, which is a lot of extra effort to avoid clip testing 1 thing out of hundreds).
Clip QSG2 scaled alias models with a scaled bbox.
