Date Version Notes
|
|
|
|
|
----------------------------------------------------------------
|
|
|
|
|
2001-12-03 1.2 (ydnar) Alpha Initial version (win32)
|
|
|
|
|
|
|
|
|
|
2001-12-03 1.2 (ydnar 2) Alpha Tolerance expanded
|
|
|
|
|
(more brush faces caught)
|
|
|
|
|
|
|
|
|
|
2001-12-04 1.2 (ydnar 3) Alpha Detail faces inside other
|
|
|
|
|
detail brushes now culled,
|
|
|
|
|
Small against large detail
|
|
|
|
|
faces also culled.
|
|
|
|
|
|
|
|
|
|
2001-12-04 1.2 (ydnar 4) Alpha djbob found a bug where
|
|
|
|
|
coincident caulk faces
|
|
|
|
|
were causing textured
|
|
|
|
|
faces to be caulked. Fixed.
|
|
|
|
|
|
|
|
|
|
2001-12-04 1.2 (ydnar 7) Alpha 5 and 6 were internal test
|
|
|
|
|
versions. This version
|
|
|
|
|
takes into account extra
|
|
|
|
|
surface info, so coplanar
|
|
|
|
|
clip brushes no longer
|
|
|
|
|
cull away textured sides.
|
|
|
|
|
|
|
|
|
|
2001-12-22 1.2 (ydnar 8) Alpha Optimized light. Lighting
|
|
|
|
|
for most maps should now
|
|
|
|
|
be measurable in minutes
|
|
|
|
|
as opposed to hours.
|
|
|
|
|
|
|
|
|
|
2001-12-24 1.2 (ydnar 9) Alpha Fixed light. It is still
|
|
|
|
|
faster, but to enable
|
|
|
|
|
"blinding fast" mode,
|
|
|
|
|
you must supply the -fast
|
|
|
|
|
switch on the commandline
|
|
|
|
|
after -light. Fast mode
|
|
|
|
|
should be approximately
|
|
|
|
|
2x as fast as build 8.
|
|
|
|
|
|
|
|
|
|
2001-12-24 1.2 (ydnar 10) Alpha Grid lighting is now
|
|
|
|
|
optimized. Not as much
|
|
|
|
|
as I would like, but
|
|
|
|
|
a distance^2 cull before
|
|
|
|
|
traces on EVERY SINGLE
|
|
|
|
|
SURFACE LIGHT IN THE MAP
|
|
|
|
|
certainly speeds things
|
|
|
|
|
the fuck up. -fast not
|
|
|
|
|
necessary to see this
|
|
|
|
|
optimization. Also added
|
|
|
|
|
the -cheap switch to
|
|
|
|
|
limit light contributions
|
|
|
|
|
to a point when it exceeds
|
|
|
|
|
255 in R, G, and B. This
|
|
|
|
|
*may* cause artifacts.
|
|
|
|
|
Test away...
|
|
|
|
|
|
|
|
|
|
2001-12-24 1.2 (ydnar 11) Alpha Now using PVS data (vis).
|
|
|
|
|
Well constructed and
|
|
|
|
|
hinted maps should now
|
|
|
|
|
see a bit of a speedup.
|
|
|
|
|
Lights in the void are
|
|
|
|
|
also now removed as a
|
|
|
|
|
byproduct.
|
|
|
|
|
|
|
|
|
|
2001-12-24 1.2 (ydnar 12) Alpha Fixed bug that caused
|
|
|
|
|
vlight to crash.
|
|
|
|
|
|
|
|
|
|
2001-12-27 1.2 (ydnar 13) Alpha - Fixed broken PVS check.
|
|
|
|
|
- Cheap now supresses sun
|
|
|
|
|
Sun trace skipped if
|
|
|
|
|
sample is "cheapened."
|
|
|
|
|
- Experimental -smooth
|
|
|
|
|
option for subsampling
|
|
|
|
|
shadow edges.
|
|
|
|
|
- Experimental radiosity
|
|
|
|
|
code. Will probably crash.
|
|
|
|
|
- Other minor optimizations.
|
|
|
|
|
|
|
|
|
|
2001-12-27 1.2 (ydnar 14) Alpha Build 13 always subsampled,
|
|
|
|
|
making it slower. Fixed.
|
|
|
|
|
|
|
|
|
|
2001-12-28 1.2 (ydnar 15) Alpha Bad windings from edge- or
|
|
|
|
|
vertex- manipulated brushes
|
|
|
|
|
no longer created. Vertex
|
|
|
|
|
lighting on func_* with
|
|
|
|
|
an origin now works.
|
|
|
|
|
Radiosity should be more
|
|
|
|
|
stable (but not fully
|
|
|
|
|
correct yet). Light
|
|
|
|
|
envelopes now properly
|
|
|
|
|
calculated for entities
|
|
|
|
|
with origins.
|
|
|
|
|
|
|
|
|
|
2001-12-28 1.2 (ydnar 16) Alpha Un-vised maps will now light.
|
|
|
|
|
|
|
|
|
|
2001-12-30 1.2 (ydnar 17) Alpha Radiosity. Use q3map_bounce
|
|
|
|
|
in shaders to specify
|
|
|
|
|
amount of light to reflect.
|
|
|
|
|
Use -bounce N after -light
|
|
|
|
|
to enable radiosity. Use
|
|
|
|
|
-dump to emit radiosity
|
|
|
|
|
lights as a prefab.
|
|
|
|
|
|
|
|
|
|
2001-12-31 1.2 (ydnar 18) Alpha Normalization release. New
|
|
|
|
|
features include -fastgrid,
|
|
|
|
|
-cheapgrid, and -fastbounce.
|
|
|
|
|
Running with -fastgrid and
|
|
|
|
|
-cheapgrid will produce
|
|
|
|
|
results identical to normal
|
|
|
|
|
q3map (with the lightgrid
|
|
|
|
|
being a little darker).
|
|
|
|
|
Also added q3map_nofast to
|
|
|
|
|
shaders to override -fast
|
|
|
|
|
switch for a surface light.
|
|
|
|
|
|
|
|
|
|
2002-01-01 1.2 (ydnar 19) Alpha Fixed an odd vertex lighting
|
|
|
|
|
bug (thanks Quakin) that was
|
|
|
|
|
causing sun to leak to brush
|
|
|
|
|
faces when using r_vertexlight
|
|
|
|
|
ingame. Changed a little bit
|
|
|
|
|
of the default behavior, so
|
|
|
|
|
test with vertex lighting
|
|
|
|
|
and with terrain. Minor
|
|
|
|
|
shader changes might be
|
|
|
|
|
necessary to get some maps to
|
|
|
|
|
look as before.
|
|
|
|
|
|
|
|
|
|
2002-01-01 1.2 (ydnar 20) Alpha Colored alpha shadows. Some
|
|
|
|
|
minor optimizations in
|
|
|
|
|
shadow tracing. Should be
|
|
|
|
|
slightly faster than 19.
|
|
|
|
|
|
|
|
|
|
2002-01-02 1.2 (ydnar 21) Alpha Set up colored shadows
|
|
|
|
|
properly to use
|
|
|
|
|
surfaceparm lightfilter.
|
|
|
|
|
Shaders must use this parm
|
|
|
|
|
to have colored shadows.
|
|
|
|
|
Can be used with alphashadow
|
|
|
|
|
as well.
|
|
|
|
|
|
|
|
|
|
2002-01-04 1.2.1-y1 (nightly) This version is all new,
|
|
|
|
|
based off the official
|
|
|
|
|
GtkRadiant tree, which has
|
|
|
|
|
all the previous enhancements.
|
|
|
|
|
New features include colored
|
|
|
|
|
lightgrid tracing through
|
|
|
|
|
lightfilter shaders, and
|
|
|
|
|
surfaceparm lightgrid, for
|
|
|
|
|
large/space maps with large
|
|
|
|
|
volumes. Also fixed are
|
|
|
|
|
potential broken brush
|
|
|
|
|
winding radiosity crashes.
|
|
|
|
|
Maybe.
|
|
|
|
|
|
|
|
|
|
2002-01-05 1.2.1-y2 (nightly) Merged latest CVS. Removed
|
|
|
|
|
bug where ambient was getting
|
|
|
|
|
calculated into the radiosity
|
|
|
|
|
solution for every pass,
|
|
|
|
|
leading to overbright maps
|
|
|
|
|
in a hurry. Also removed
|
|
|
|
|
the bad PTPFF reporting,
|
|
|
|
|
as it only caused problems
|
|
|
|
|
with radiosity in a big way.
|
|
|
|
|
Sue me.
|
|
|
|
|
|
|
|
|
|
2002-01-05 1.2.1-y3 (nightly) I really suck. Sample color
|
|
|
|
|
now properly cleared to 0
|
|
|
|
|
when bouncing.
|
|
|
|
|
|
|
|
|
|
2002-01-07 1.2.1-y4 (nightly) Particle Studio generated
|
|
|
|
|
brush faces should no longer
|
|
|
|
|
be culled. I no longer cull
|
|
|
|
|
faces that are autosprite.
|
|
|
|
|
Added -bouncegrid to have
|
|
|
|
|
radiosity add to lightgrid.
|
|
|
|
|
|
|
|
|
|
2002-01-08 1.2.1-y5 (nightly) Same as y4, but compiled with
|
|
|
|
|
full optimizations. Should
|
|
|
|
|
be 10-25% faster in all,
|
|
|
|
|
including BSP and vis
|
|
|
|
|
stages.
|
|
|
|
|
|
|
|
|
|
2002-01-09 1.2.1-y6 (nightly) Brushfaces with polygonoffset
|
|
|
|
|
in their shader will no longer
|
|
|
|
|
be faceculled.
|
|
|
|
|
|
|
|
|
|
2002-01-11 1.2.1-y7 (nightly) Increased stack size for threads
|
|
|
|
|
to 4MB on Win32 to (hopefully)
|
|
|
|
|
elminate stack overflow
|
|
|
|
|
crash with radiosity. Also
|
|
|
|
|
made subdivision use the heap
|
|
|
|
|
to lessen the stack load. Fixed
|
|
|
|
|
bug where q3map_bounce was not
|
|
|
|
|
being used in shader parsing.
|
|
|
|
|
Redid some of the divide math
|
|
|
|
|
to work in 0-255 instead of
|
|
|
|
|
0-256.
|
|
|
|
|
|
|
|
|
|
2002-01-11 1.2.1-y8 (nightly) More Win32 threading
|
|
|
|
|
crutches. Eat me, Bill.
|
|
|
|
|
|
|
|
|
|
2002-01-15 1.2.1-y9 RR2DO2 noticed a stupid bug
|
|
|
|
|
in my PVS code. Fixed it,
|
|
|
|
|
so the PVS light opts work as
|
|
|
|
|
they should. Lighting is
|
|
|
|
|
faster. Also got rid of some
|
|
|
|
|
redundant square roots from
|
|
|
|
|
the raytracing, speeding up
|
|
|
|
|
lighting another ~25%.
|
|
|
|
|
|
|
|
|
|
2002-01-20 1.2.1-y10 Fixed a potential crash bug
|
|
|
|
|
with maps with 0 lights. Also
|
|
|
|
|
changed how lightmaps are
|
|
|
|
|
projected onto patches that
|
|
|
|
|
lie in a single plane (bevel
|
|
|
|
|
endcaps, floors, etc). Shadows
|
|
|
|
|
now work properly on them.
|
|
|
|
|
|
|
|
|
|
2002-01-22 1.2.1-y11 Fixed a divide-by-zero crash
|
|
|
|
|
with maps with no lights or
|
|
|
|
|
no tracing. Also added
|
|
|
|
|
code to make brush/patch
|
|
|
|
|
vertex lighting more closely
|
|
|
|
|
resemble lightmap, even on
|
|
|
|
|
less-than-perfect maps. And
|
|
|
|
|
-light is faster, too...about
|
|
|
|
|
25% on q3dm17. 34->25 seconds.
|
|
|
|
|
|
|
|
|
|
2002-01-24 1.2.1-y12 Completely rewrote the path
|
|
|
|
|
argument handling. Should find
|
|
|
|
|
the Quake 3 dir and other
|
|
|
|
|
dirs properly now. Needs to
|
|
|
|
|
be tested on Linux though.
|
|
|
|
|
Also made lights linear by
|
|
|
|
|
default when run with -game
|
|
|
|
|
wolf. This is to match the
|
|
|
|
|
Gray Matter q3map and
|
|
|
|
|
entity definition.
|
|
|
|
|
|
|
|
|
|
2002-01-28 1.2.4-y1 Merged from 1.2.4-nightly CVS
|
|
|
|
|
sources. Fog sparklies gone.
|
|
|
|
|
-nopatchfix so vlight works
|
|
|
|
|
properly again. Cleaned up
|
|
|
|
|
paths processing some more,
|
|
|
|
|
including Linux stuff. Added
|
|
|
|
|
_lightmapscale entity key.
|
|
|
|
|
Brought -game wolf lighting
|
|
|
|
|
to parity with GM tools.
|
|
|
|
|
RR2DO2's PCX loading fix. A
|
|
|
|
|
bunch of other useful fun shit.
|
|
|
|
|
|
|
|
|
|
2002-01-29 1.2.4-y2 Fixed a bug in RR2DO2's PCX fix.
|
|
|
|
|
Fixed a stupid bug in lightmap
|
|
|
|
|
dimension bounds checking (thanks
|
|
|
|
|
Laerth).
|
|
|
|
|
|
|
|
|
|
2002-01-29 1.2.4-y3 Now will detect (and report to
|
|
|
|
|
GtkRadiant) all degenerate patches
|
|
|
|
|
like those created by capping a
|
|
|
|
|
cone.
|
|
|
|
|
|
|
|
|
|
2002-02-23 2.0.0-a1 thru a3 Rewrote about 30% of the code.
|
|
|
|
|
Lots of cool new shit.
|
|
|
|
|
|
|
|
|
|
2002-02-24 2.0.0-a4 thru a8 Terrain fix (thx Pointy), patches
|
|
|
|
|
are no longer circus colored, more
|
|
|
|
|
terrain texturing fixes.
|
|
|
|
|
|
|
|
|
|
2002-02-26 2.0.0-a10 thru a11 Adjacent coplanar surfaces now
|
|
|
|
|
will share lightmaps. This prevents
|
|
|
|
|
most wierd edge cases with filter
|
|
|
|
|
and speeds things up a bit. Patches
|
|
|
|
|
too.
|
|
|
|
|
|
|
|
|
|
2002-02-27 2.0.0-a12 More lightmap fixes for non-planar
|
|
|
|
|
surfaces. Bugfixes in allocation/
|
|
|
|
|
compression of lightmaps as well.
|
|
|
|
|
|
|
|
|
|
2002-03-02 2.0.0-a13 Fixed some surface light bugs,
|
|
|
|
|
adjusted the occluded-luxel finding
|
|
|
|
|
code, and amped the radiosity. Other
|
|
|
|
|
fixes to RTCW lighting code (better
|
|
|
|
|
angle attenuation on linear lights).
|
|
|
|
|
|
|
|
|
|
2002-03-04 2.0.0-a14 Vertex light should now be near-
|
|
|
|
|
perfect on clean (and mostly on not-
|
|
|
|
|
so-clean) maps. Unlit maps will no
|
|
|
|
|
longer have tri-fanned brush faces
|
|
|
|
|
with random vertex colors. VLight is
|
|
|
|
|
now totally gone (reverts to -light).
|
|
|
|
|
|
|
|
|
|
2002-03-06 2.0.0-a15 Relaxed the planar check, should now
|
|
|
|
|
classify all slightly-off plane brush
|
|
|
|
|
face metasurfaces as planar. Triangle
|
|
|
|
|
checking much more stringent as well.
|
|
|
|
|
|
|
|
|
|
2002-03-11 2.0.0-a16 Vis crash gone. Lightmap allocation
|
|
|
|
|
now sorted by shader to minimize
|
|
|
|
|
shader count (and lessen chance for
|
|
|
|
|
RTCW shader substitution bug). Hit
|
|
|
|
|
big quarter-century also.
|
|
|
|
|
|
|
|
|
|
2002-03-12 2.0.0-a17 Dammit.
|
|
|
|
|
|
|
|
|
|
2002-03-12 2.0.0-a18 Hunting phantom lights...
|
|
|
|
|
|
|
|
|
|
2002-03-16 2.0.0-a19 Fogclip and _celshader. Check the
|
|
|
|
|
extras folder...
|
|
|
|
|
|
|
|
|
|
2002-03-18 2.0.0-b1-rc1 Beta release candidate. Fixed the
|
|
|
|
|
stupid phantom light bug finally.
|
|
|
|
|
Tricked out the sun tracing a wee
|
|
|
|
|
bit as well, should be a little
|
|
|
|
|
faster + more accurate. Other little
|
|
|
|
|
bits fixed up as well. Thanks to K,
|
|
|
|
|
{wf}ShadowSpawn and RR2DO2 for their
|
|
|
|
|
help tracking these last bugs down.
|
|
|
|
|
|
|
|
|
|
2002-03-19 2.0.0-b1-rc2 Increased some maximums, and got
|
|
|
|
|
rid of some cruft.
|
|
|
|
|
|
|
|

2002-03-22 2.0.0-b1-rc3 Some minor optimizations.
|
|
|
|
|
|
|
|
|
|
2002-03-30 2.0.0-b1-rc5 Now with fur (see extras/fur.shader).
|
|
|
|
|
|
|
|
|
|
2002-04-01 2.0.0-b1-rc6 Enhanced with baby seal technology.
|
|
|
|
|
|
|
|
|
|
2002-05-01 2.0.1 OK, better late than never. Fixed the
|
|
|
|
|
alphashadow = 255 = transparent bug.
|
|
|
|
|
|
|
|
|
|
2002-06-24 2.1.0-b1 Added _foghull functionality. Works
|
|
|
|
|
like terrain "_shader" where
|
|
|
|
|
you don't need "textures/" prefix.
|
|
|
|
|
Also added q3map_normalmap. See
|
|
|
|
|
NVIDIA's website for Photoshop filter
|
|
|
|
|
to generate normalmaps from grayscale
|
|
|
|
|
heightmaps. This makes lightmaps
|
|
|
|
|
look bumpmapped. Currently 50% broken.
|
|
|
|
|
|
|
|
|
|
2002-07-06 2.2.0-b1 Empty epairs now stripped from map,
|
|
|
|
|
fixing Wolfenstein crash bug. Func_*
|
|
|
|
|
entities are now fogged properly.
|
|
|
|
|
Sort of. This will be enhanced later.
|
|
|
|
|
Added the .srf file to store all the
|
|
|
|
|
extra crap I was hiding in the BSP.
|
|
|
|
|
It's an editable text file that
|
|
|
|
|
-light uses, so you can change the
|
|
|
|
|
samplesize w/o recompiling the map
|
|
|
|
|
(just -light'ing it). Changed color
|
|
|
|
|
normalization to clamping, because
|
|
|
|
|
it looks better. Other stuff got
|
|
|
|
|
fixed as well.

2002-07-08 2.2.0-b2 thru b11 Test versions. Thanks jer and jet!

|
2002-07-09 2.2.0-b12 Larger-than-life lightmaps are now
|
|
|
|
|
supported, up to 1024x1024. Add
|
|
|
|
|
q3map_lightmapSize H W to a shader
|
|
|
|
|
to use. Lightmaps are stored in
|
|
|
|
|
maps/{mapname}/_lm_NNN.tga and a
|
|
|
|
|
shader script q3map_{mapname}.shader
|
|
|
|
|
is generated. Also added
|
|
|
|
|
q3map_lightmapGamma N.N. Use a
|
|
|
|
|
value of 2.0 to simulate
|
|
|
|
|
r_overBrightBits 1 and
|
|
|
|
|
r_mapOverBrightBits 2 on external
|
|
|
|
|
lightmap images.
