TRANSLATE 3

PXTR3

CALL SEQUENCE

CALL PXTR3 (DX, DY, DZ, ITYPE)

INPUT PARAMETERS

REAL DX

X translation in MC

REAL DY

Y translation in MC

REAL DZ

Z translation in MC

INTEGER ITYPE

Composition flag

0	PCPRE	pre-concatenate
1	PCPOST	post-concatenate
2	PCREPL	replace

EFFECT

This function first computes a 3D transformation matrix based on the specified translation parameters. Depending on the edit mode, the transformation matrix is then inserted into the open structure after the current element or replaces the current element. The newly inserted element becomes the current element.

It is equivalent to calling the following two routines in sequence:

CALL PTR3 (DX, DY, DZ, IERR, XFORM)
CALL PSLMT3 (XFORM, ITYPE)

where XFORM is a 4x4 transformation matrix.

During structure traversal, the local modeling transformation is modified as specified by the composition flag. See Insert Local Transformation 3 (routine PSLMT3) for details.

ERRORS

5

Ignoring function, function requires either state STNOP or state STOP.
