SCALE 3

PSCALE3

CALL SEQUENCE

void pscale3(

const Pvec3	*scale_vector	/* scale vector	*/
Pint	*error_ind	/* (out) error indicator	*/
Pmatrix3	result	/* (out) transformation matrix	*/

)

TYPES

typedef struct {
	Pfloat 	delta_x;	/* delta x	*/
	Pfloat 	delta_y;	/* delta y	*/
	Pfloat 	delta_z;	/* delta z	*/
} Pvec3;

typedef Pfloat Pmatrix3[4][4];

PHIGS STATE

EFFECT

Returns a homogeneous 4 x 4 matrix to be used for the 3D scaling defined by scale_vector.

The returned matrix can be used as the transformation matrix for the SET LOCAL TRANSFORMATION MATRIX 3, SET GLOBAL TRANSFORMATION MATRIX 3 and similar functions.

ERRORS

2

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