COMPOSE TRANSFORMATION MATRIX 3

PCOTM3

CALL SEQUENCE

CALL PCOTM3	(XFRMTI, XO, YO, ZO, DX, DY, DZ, PHIX, PHIY, PHIZ, FX, FY, FZ, ERRIND, XFRMTO)

INPUT PARAMETERS

REAL XFRMTI

Homogeneous (4 x 4) 3D transformation matrix.

REAL XO, YO, ZO

3D point defined in Modelling Coordinate which will be the centre of The rotation and of the scale factor.

REAL DX, DY, DZ

Vector defining the translation.

REAL PHIX, PHIY, PHIZ

Rotation angle in radians (positive angle: anticlockwise direction; negative angle: clockwise direction).

REAL FX, FY, FZ

Scale factors defined for each direction

OUTPUT PARAMETERS

INTEGER ERRIND

Error indicator

REAL XFRMTO

Homogeneous (4 x 4) matrix resulting from the composition of the XFRMTI matrix and the translation defined by (DX, DY, DZ), rotation (PHIX, PHIY, PHIZ) and scaling (FX, FY,FZ).

PHIGS STATE

EFFECT

Returns a homogeneous 4 x 4 matrix built from a homogeneous 4 x 4 matrix and by scaling, x rotation, y rotation, z rotation and translation.

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, *,*,*)
