T3d Keyword
Used With Routines: AXIS, CONTOUR, CONTOURFS, CONTOUR2, OPLOT, PLOT, PLOTS, POLYFILL, SHADE_SURF, SHADE_SURF_IRR, SURFACE, XYOUTS
Corresponding System Variable: !P.T3d
note | When the T3d keyword is in effect, the CONTOUR2 Fill keyword is disabled. |
A keyword flag which, if present, indicates that the generalized transformation matrix in !P.T is to be used.
!P.T must contain a valid transformation matrix before the T3d keyword can be used. The matrix can be set by using the Save plotting keyword with the appropriate plotting routine.
If T3d is not present the user-supplied coordinates are simply scaled to screen coordinates. See the examples in the description of the Save plotting keyword.
A valid transformation matrix can be placed in !P.T in several ways:
Use the Save keyword to save the transformation matrix from an earlier graphics operation. Establish transformation matrix using T3D standard library procedure. Set the value of !P.T directly.
