Bill Currie 215d2e9747 Add a function to decompose a matrix.
The function gives rotation(quaternion), scale, shear, and translation (all
three as vectors), shear is (XY, XZ, YZ).

Bill Currie 8791b35e55 Add support for half floats.
iqm and OpenGL use them, so they might come in handy. The tests use values
from wikipedia and a couple extra.

Bill Currie efaef89c5f Add a shortcut function for quaterion/vector multiplication.
I got the idea from blender when I discovered by accident that quat * vect
produces the same result as quat * qvect * quat* and looked up the code to
check what was going on. While matrix/vector multiplication still beats the
pants off quaternion/vector multiplication, QuatMultVec is a slight
optimization over quat * qvect * quat* (17+,24* vs 24+,32*, plus no need to
to generate quat*).

Bill Currie bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

Bill Currie cbd13ac54e Implement QuatExp and fix up QuatBlend's param names. 2012-01-12 21:22:06 +09:00
Bill Currie ea2ae1436c Fix some bugs in the new matrix functions/macros. 2011-12-31 13:20:31 +09:00
Bill Currie 35bf957d08 Add a 4x4 matrix type and some functions for it. 2011-12-30 20:11:53 +09:00
Bill Currie 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.

Bill Currie 12e238f806 Add a function to convert quake angles to a quaternion.
The test works by comparing the result of AngleVectors with forward,
right, and up vectors rotated by the quaternion resulting from AngleQuat.

Bill Currie fe3cdbcf5a fix a snafu in quattomat 2011-09-04 09:58:12 +09:00
Bill Currie eb205d73fd Add a function to convert a quaternion to a rotation matrix. 2011-09-04 09:58:12 +09:00
Bill Currie 33db650161 Add QuatInverse to calculate 1/q.
There's still no direct quaternion division because I don't know if the
definition of q1/q2 is (1/q2)*q1 or q1*(1/q2) (it does make a difference).
2011-01-18 22:22:18 +09:00
Bill Currie 13503198e5 Add quat_origin convenience constant.
Same as vec3_origin in that all elements are zero.

Bill Currie 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
Bill Currie 3fb03fc2be hah, should have been using __attribute__((used)) all that time (rather
than __attribute__((unused))). fixes the missing console in -x11

Bill Currie 4c4f40f137 fix a few bugs. basics seem to be working 2004-04-08 05:13:24 +00:00
Bill Currie 39685d0c63 more readability and add the quaternion functions 2004-04-07 18:01:45 +00:00
Bill Currie 19ef80c555 this should fix static win32 builds 2004-01-21 00:15:35 +00:00
Bill Currie 7ead5a91f8 don't let gcc automaticly inline functions but make gcc inline bigger
functions when told to. also make gcc warn if it can't inline a function.

Explicitly inline several functions (including moving VectorNormalize to
mathlib.h so it /can/ be) resulting in a 5.5% speedup for spam2 (88 to 92
fps)
2003-08-11 06:05:07 +00:00
Bill Currie 6a94607d9d rename VectorMA to VectorMultAdd, add VectorMultSub and use it in a few
places. Not certain how much speed difference it makes :/

Bill Currie 72d1343735 add some comments about the coordinate systems used in AngleVectors 2003-03-10 20:44:50 +00:00
Bill Currie 761a7546dd re-arrange things so __attribute__ and __builtin_expect are properly
autoconfiscated so rcsid will continue to work with gcc 3.3
2003-01-15 15:31:36 +00:00
Bill Currie 71196fedf6 make gcc more anal about prototypes, string constants and function
visibility (ie, global functions must have a prototype)

Bill Currie d25ee82838 provide a tighter accuracy (but slower) _VectorNormalize for the tools 2002-09-25 21:35:49 +00:00
Bill Currie 56843557f6 make _VectorCompare use EQUAL_EPSILON (VectorCompare is still the fast
macro) and use it instead of VectorCompare in the map tools. This (and, it
seems, RINT) fixes qfbsp on spc. Also, jump /all/ entities that get hit
by the filler in qfbsp

Ragnvald Maartmann-Moe IV fd1ded5c4a Add r_nearclip and r_particles_nearclip. Also put some limits on r_farclip. And fix id's insane max and min float, and some minor improvements in frustum setup in GL. 2002-06-26 22:20:12 +00:00
Bill Currie 44dcf74627 strip the \n from all(?) of the Sys_Error calls (Sys_Error itself will be
adding \n).

Bill Currie 630aa80dc4 various cleanups including TODOs and FIXMEs and rewrite va to use a dynamic
buffer.

Bill Currie 36bb62c3c5 rewrite CrossProduct so memory is accessed more linearly. should provide
a tiny speedup for servers and clipped skyboxes

Ragnvald Maartmann-Moe IV edcf092b05 Whitespace, dammit. Oh, and removal of several orphaned comments. Comments in front of functions suck. 2001-08-22 22:03:16 +00:00
Zephaniah E. Hull 8f011f91ec Length is now a #define, not a bloody function! 2001-08-15 23:01:56 +00:00
Bill Currie 647d38fa40 Make R_MarkLights use the vis info to speed things up. Oddly, even though
R_MarkLights is now about 3% instead of about 15%, I've lost 8 fps on my
null GL speed test. However, R_AddDynamicLights has jumped up a bit, so I'm
wording if maybe more surfaces are being lit.
2001-08-05 04:01:45 +00:00
Bill Currie cc68e1a12e qf now links with NO optimisation (not even -O). R_CullBox has been moved from
glquake.h to mathlib.h (along with the declaration for frustum) and the
extern inline keyworws protected by an ifndef so that mathlib.c can cause
R_CullBox to be compiled publicly. The definition of frustrum has been moved
from its verious locations into mathlib.c.

Zephaniah E. Hull a16b2c0070 Borrowed LH's VectorVectors.
Changed smoke trails a good bit.

Bill Currie f78b973978 move the api headers into include/QF and clean up (most of) the resulting mess.
target specific files that I don't build won't compile yet. just put QF/
infront of the offending headers.

Also move ver_check into libqfutils
