       Object oriented style (method):

SYNOPSIS
publicstatic void CairoMatrix::initRotate (float $radians) DESCRIPTION
Procedural style: object cairo_matrix_init_rotate (float $radians) Creats a new matrix to a transformation that rotates by radians provided PARAMETERS
o $radians - angle of rotation, in radians. The direction of rotation is defined such that positive angles rotate in the direction from the positive X axis toward the positive Y axis. With the default axis orientation of cairo, positive angles rotate in a clockwise direction. RETURN VALUES
Returns a new CairoMatrix object that can be used with surfaces, contexts, and patterns. EXAMPLES
Example #1 Object oriented style <?php /* Create a new Matrix */ $matrix = CairoMatrix::initRotate(0.3); ?> Example #2 Procedural style <?php /* Create a new Matrix */ $matrix = cairo_matrix_init_rotate(0.3); ?> SEE ALSO

get_rotation_matrix(3alleg4)					  Allegro manual				      get_rotation_matrix(3alleg4)

NAME
get_rotation_matrix, get_rotation_matrix_f - Constructs X, Y, Z rotation matrices. Allegro game programming library. SYNOPSIS
#include <allegro.h> void get_rotation_matrix(MATRIX *m, fixed x, fixed y, fixed z); void get_rotation_matrix_f(MATRIX_f *m, float x, float y, float z); DESCRIPTION
Constructs a transformation matrix which will rotate points around all three axes by the specified amounts (given in binary, 256 degrees to a circle format). The direction of rotation can simply be found out with the right-hand rule: Point the dumb of your right hand towards the origin along the axis of rotation, and the fingers will curl in the positive direction of rotation. E.g. if you rotate around the y axis, and look at the scene from above, a positive angle will rotate in clockwise direction. SEE ALSO
