The first transforms - * Rz' and Ry' are considered inverses, since the data from the - * arbitrary axis gives you info on how to get to it, not how - * to get away from it, and an inverse must be applied. - * - * The basic calculation used is to recognize that the arbitrary - * axis vector (x, y, z), since it is of unit length, actually - * represents the sines and cosines of the angles to rotate the - * X-axis to the same orientation, with theta being the angle about - * Z and phi the angle about Y (in the order described above) - * as follows: - * - * cos ( theta ) = x / sqrt ( 1 - z^2 ) - * sin ( theta ) = y / sqrt ( 1 - z^2 ) - * - * cos ( phi ) = sqrt ( 1 - z^2 ) - * sin ( phi ) = z - * - * Note that cos ( phi ) can further be inserted to the above - * formulas: - * - * cos ( theta ) = x / cos ( phi ) - * sin ( theta ) = y / sin ( phi ) - * - * ...etc. Because of those relations and the standard trigonometric - * relations, it is pssible to reduce the transforms down to what - * is used below. 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.
