5b054dd98b Add "slow grav" for smoke.
Removes one more set of hard codings from particle types.

5a5b31bae4 Correct the direction of pt_fire particles.
sub_grav() was accelerating the particle in the wrong direction. Down being
+ve gravity caused a bit of confusion (though it was a c&p error).

372defc1be Support up to 128 dlights.
More or less as per MH's tut, but really just finishing something that
should have been done years ago.

7d8b0f96d6 Correct the fog distance calculations.
It turns out the pixel's z coord is correctly obtailed by
gl_FragCoord.z/gl_FragCoord.w.

c4309e7abc Correct the fog blend calculation for transparency.
The incoming pixel's alpha should not be affected by fog. This fixes the
ugly square smoke particles in foggy maps.

a7327acb80 Set up shadevector for gl alias models.
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.

fbc0ad59df Implement gl shadows for pure triangle alias models.
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.

8333e6578c Fix non-static sw renderer for 32bit x86.
Yet another undefined symbol caused by iqm support. This time caused by
asm/not asm.

f9c6eacb84 Really fix sw32 renderer loading.
It seems I never tested the sw32 renderer in a non-static build since I put
in IQM support.

fd6b5edb73 Don't set triangle draw type in sw32 iqm renderer.
It's not used and causes link errors (I never noticed on my system).

6fe32103ea Do a bit of bound() usage auditing.
While these seem to be mostly harmless, having function calls in the
bounded value can be nasty.

a822a683cd Fix the inverted lighting for sw32.
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.

12319cfcdf Revert "Slightly reducde the number of calls to glUniformMatrix4fv."
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.

ede65fb28c Use the correct source for the backtile width/height.
Yay, no more garbage on the screen :)

5014825b39 Fix the backtile for glsl.
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).

37260018a2 Acutally use the vertex colors for alias models.
Thanks to Spirit trying QF on nvidia drivers, the missing attributes were
found. Now he shouldn't get gl errors :)

dbbd6f4535 Fix a couple of missing particle function pointers.
Discovered while getting the location markers working again.

ef9e8d05c4 Avoid some unnecessary state changes.
Doesn't make much difference but it doesn't hurt.

ee1cb24e3d Move the call to R_SetFrustum to gl_R_SetupFrame.
This was meant to be part of the previous commit, but I forgot to write the
file :P

a8e0bcabf9 Call R_SetFrustum in all renderers.
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 :)

e58cd75660 Bound r_maxdlights properly.
QF's implementation doesn't support more than 32 dlights (32 bit int).

b25de4d995 Rewrite the 2d code to use a scrap.
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).

df35b22af4 Parameterize the linear filtering of scrap textures. 2012-07-03 12:10:24 +09:00

e170f4ee75 Slightly reducde the number of calls to glUniformMatrix4fv.
It doesn't make a big difference to bigass1 (yet ?), but it does clean up
apitrace a little.

1a6b56b0a2 Call glTexSubImage2D only once per frame.
Instead of once per surface... ouch. Gives about 20% speed boost on demo1
(154.7->185.7)

4da3be5cd6 Get a minor speed gain in glsl bsp rendering.
About 4% (99.5 to 104.4) from not calling VertexAttrib4fv or BindTexture
when not necessary.

aa2a8e8909 Mostly "merge" cl_screen.c.
Down to protocol/networking differences.

b2290d92c9 Nuke UNALIGNED_OK.
It's not really necessary (and was effectively dead anyway).

Lots of trailing whitespace and otherwise blank lines.

85da69a96a Transform normals wrt bones in sw and sw32.
Better lighting :), though any scaling/shearing will produce funny results,
and sw32's lighting is broken in general.

0fbaa2a88a Add sw32 support for iqm models.
That was easy :)

e2db2dcb63 Support static iqm models.
Segging on a model with no animations is not nice :P

d25f39cc7d Remove pskindesc from affinetridesc_t.
It's never used after being set.

be9c0697a2 Give sw iqm its own transform setup.
IQMs don't need to be scaled or offset. This fixes iqms not rendering,
though they actually were: just super tiny.

c0517b1d97 Factor out the blend palette creation.
gl, sw and sw32 use blend palettes, so share the code. This also abandons
the optimization for transforming verts in sw (had all sorts of problems
anyway). sw still doesn't work, though.

fb10f38fd4 SW now tries (but fails miserably) to render iqm models.
Something seems to be very wrong with the transforms.

da87ac0ce5 Remove some unused parameters. 2012-05-17 21:33:22 +09:00

da313cfae7 Load iqm models in the sw renderers.
sw32 loses 32 bit textures :/
loading is /slow/ (converting rgb(a) to 8bit palette... ouch.

7637f35616 Remove the test scaling.
Heh, forgot to remove it again :)

c3801d46e5 Render iqm models in GL.
There are still many issues to sort out, but the basics are working.

Problems:
	rendered fullbright (no lighting done)
	normals are ignored
	extra textures (glow etc) not used/loaded

4 models on the screen don't seem to be a problem.

f958afad53 Optionally allocate extra data for iqm blend frames.
Also, correct the blend parameter type (int->float. oops).

c0df07b607 Enable loading of iqm models in gl.
They don't render yet, but the engine doesn't segfault.
The vertex blend indices are rewritten with blend palette indices.

041d63c828 Move the frame blending into common code. 2012-05-16 17:44:18 +09:00

8ada7c02a3 Remove the vertex scaling.
It was there only because mrfixit is rather small (8qu?) and it made
finding him easier :). Anyway, any scaling should be done in the engine.
