CALL SEQUENCE

void pcompose_matrix(

Pmatrix	mat_a	/* matrix a	*/
Pmatrix	mat_b	/* matrix b	*/
Pint	*error_ind	/* (out) error indicator	*/
Pmatrix	result	/* (out) result matrix	*/

)

TYPES

typedef Pfloat Pmatrix[3][3];

PHIGS STATE

EFFECT

Returns a homogeneous 3 x 3 matrix which is the product of mat_a and mat_b (mat_a X mat_b).

The returned matrix can be used as the transformation matrix for the SET LOCAL TRANSFORMATION MATRIX, SET GLOBAL TRANSFORMATION MATRIX and similar functions.

ERRORS

2

Ignoring function, function requires state (PHOP, *,*,*)
