Move the transform and lighting code to two new directories
math: Provides basic matrix and vector functionality that
might be useful to multiple software t&l
implementations, and is used by core mesa to
manage the Model, Project, etc matrices.
tnl: The real transform & lighting code from core mesa,
including everything from glVertex3f through vertex
buffer handling, transformation, clipping, lighting
and handoff to a driver for rasterization.
The interfaces of these can be further tightened up, but the basic
splitting up of state and code move is done.

It may be that any primary axis chosen will give the - * same results (modulo a sign convention) using thie method. - * - * Particularly nice is to notice that all divisions that might - * have caused trouble when parallel to certain planes or - * axis go away with care paid to reducing the expressions. - * After checking, it does perform correctly under all cases, since - * in all the cases of division where the denominator would have - * been zero, the numerator would have been zero as well, giving - * the expected result. - */ - - xx = x * x; - yy = y * y; - zz = z * z; - xy = x * y; - yz = y * z; - zx = z * x; - xs = x * s; - ys = y * s; - zs = z * s; - one_c = 1.0F - c; - - M(0,0) = (one_c * xx) + c; - M(0,1) = (one_c * xy) - zs; - M(0,2) = (one_c * zx) + ys; - M(0,3) = 0.0F; - - M(1,0) = (one_c * xy) + zs; - M(1,1) = (one_c * yy) + c; - M(1,2) = (one_c * yz) - xs; - M(1,3) = 0.0F; - - M(2,0) = (one_c * zx) - ys; - M(2,1) = (one_c * yz) + xs; - M(2,2) = (one_c * zz) + c; - M(2,3) = 0.0F; - - M(3,0) = 0.0F; - M(3,1) = 0.0F; - M(3,2) = 0.0F; - M(3,3) = 1.0F; - -#undef M -} - -#define ZERO(x) (1<<x) -#define ONE(x) (1<<(x+16)) - -#define MASK_NO_TRX (ZERO(12) | ZERO(13) | ZERO(14)) -#define MASK_NO_2D_SCALE ( ONE(0) | ONE(5)) - -#define MASK_IDENTITY ( ONE(0) | ZERO(4) | ZERO(8) | ZERO(12) |\ - ZERO(1) | ONE(5) | ZERO(9) | ZERO(13) |\ - ZERO(2) | ZERO(6) | ONE(10) | ZERO(14) |\ - ZERO(3) | ZERO(7) | ZERO(11) | ONE(15) ) - -#define MASK_2D_NO_ROT ( ZERO(4) | ZERO(8) | \ - ZERO(1) | ZERO(9) | \ - ZERO(2) | ZERO(6) | ONE(10) | ZERO(14) |\ - ZERO(3) | ZERO(7) | ZERO(11) | ONE(15) ) - -#define MASK_2D ( ZERO(8) | \ - ZERO(9) | \ - ZERO(2) | ZERO(6) | ONE(10) | ZERO(14) |\ - ZERO(3) | ZERO(7) | ZERO(11) | ONE(15) ) - - -#define MASK_3D_NO_ROT ( ZERO(4) | ZERO(8) | \ - ZERO(1) | ZERO(9) | \ - ZERO(2) | ZERO(6) | \ - ZERO(3) | ZERO(7) | ZERO(11) | ONE(15) ) - -#define MASK_3D ( \ - \ - \ - ZERO(3) | ZERO(7) | ZERO(11) | ONE(15) ) - - -#define MASK_PERSPECTIVE ( ZERO(4) | ZERO(12) |\ - ZERO(1) | ZERO(13) |\ - ZERO(2) | ZERO(6) | \ - ZERO(3) | ZERO(7) | ZERO(15) ) - -#define SQ(x) ((x)*(x)) - -/* Determine type and flags from scratch.
