3.8 Coordinate transformations (frames)
$P_PFRAME = CMIRROR(X, Y, Z)
The syntax for $P_CHBFRAME[<n>] is identical to $P_PFRAME.
Meaning
CTRANS:
CROT:
CSCALE:
CMIRROR:
X, Y, Z:
<offset value>:
<angle>:
<scale>:
Examples
Value assignments to frame components of the current programmable frame
Value assignment to the translation, rotation and mirror frame components of the current
programmable frame:
$P_PFRAME = CTRANS(X,10,Y,20,Z,5) : CROT(Z,45) : CMIRROR(Y)
Writing the rotation components of a frame
Assignment of values to all three axes of the rotation component of the settable data storage
frame $P_UIFR with CROT :
$P_UIFR[5] = CROT(X, 0, Y, 0, Z, 0)
