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.

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*).

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

edb05fdfce Rename Vector3Scale and QuatCompScale.
They are now VectorCompMult and QuatCompMult.

cc5140e3a1 Move min/max/bound and field_offset into better locations.
min/max bound into mathlib.h (they /are/ math functions, after all) and
field_offset into qtypes.h.

8b78aeb666 Add component-wise vector and quaternion comparison macros.
Also, re-implement VectorCompare and QuatCompare using the new macros.

VectorCompCompare and QuatCompCompare take a parameter specifying the
comparison operator to use. All component-wise comparisons must be true
for the whole comparison to be true.

3a386293fc Add Vector3Scale macro.
Vector3Scale individually scales the components of one vector by the
components of another vector.

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.

94362cc010 Add macros to ease printing of vectors and quaternions.
I got sick of having to pass all those parameters to printf. Let the
compiler do it for me.

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.

eb205d73fd Add a function to convert a quaternion to a rotation matrix. 2011-09-04 09:58:12 +09:00

a59fee5346 Add the QuatSet macro.
Same as the VectorSet macro.

d638fdce83 Add a PlaneFlip macro. 2011-05-07 19:29:03 +09:00

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).

13503198e5 Add quat_origin convenience constant.
Same as vec3_origin in that all elements are zero.

8808eba3ff add VectorSet macro
VectorSet(a,b,c,d) -> vec3_t d = (a, b, c)

This should be useful.

fc293864dc Fix visibility of VectorNormalize and other math functions 2007-03-17 21:06:00 +00:00
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

6fbddc3d43 so that's the right way to do groups and subgroups... 2006-12-05 11:40:00 +00:00

8770df39e5 start documenting things (progs building still borked)
This is an imperfect revision of history.

29502c8f5a Lots of optimizations, particularly for GL state changes, and tweak lighting a
bit more.

Also a cleanup from Grievre: Use VectorIsZero in two places in gl_mod_alias.c.

77b2942982 several libs can now get built as dlls in windows: console, gamecode,
gamecode_builtins, gib, image, modules, object, ruamoko and util.

231a1bfb56 bring in many of LordHavoc's changes to qbsp: HalfLife WorldCraft texture
alighnment, partial "point of plane" autocorrection (currently disabled: I
want to make it optional), large map support (not sure where that's
hiding), hipnotic entity rotation

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)

6a94607d9d rename VectorMA to VectorMultAdd, add VectorMultSub and use it in a few
places. Not certain how much speed difference it makes :/

71196fedf6 make gcc more anal about prototypes, string constants and function
visibility (ie, global functions must have a prototype)

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

32a85e7130 Clipping cleanups.
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.

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

def8bb3cd5 LordHavoc's VectorIsNull changes from 0.3 but as VectorIsZero (no such thing
as a `null' vector) plus a couple of other bits from his patch.
