DEFINITION OF A 3D VIEW IN THE XY-PLANE
CALL SEQUENCE
TV3PXY (WKID, VIEWID, XC, YC, ZC , TPVIEW, ZOOM, VIEWPT)
INPUT PARAMETERS
INTEGER WKID
INTEGER VIEWID
REAL XC,YC,ZC
INTEGER TPVIEW
REAL ZOOM
REAL VIEWPT (6)
ARGUMENTS
- WKID
- Identifier of the workstation on which the view is defined.
- VIEWID
- Index of the view to define.
- XC,YC,ZC
- Coordinates (in normalized space [0-1] × [0-1] × [0-1]) of the
point in the scene to center on.
- TPVIEW
- A value from 1 to 8 - eight view types for the XY-plane are possible
- ZOOM
- Zoom factor to apply to the image.
- 1
- the image is normal
- 2
- the image is enlarged to twice the normal size
- 0.5
- the image size is reduced to half its normal size, etc)
- VIEWPT
- Viewport (see TVIEWC).
EFFECT
This function defines the view identified by the integer VIEWID. The observer
looks toward the point XC,YC,ZC from a direction perpendicular to plane XY.
This view is not defined in perspective and therefore corresponds to a
representation of the cut-plane XY. Eight different types of view are possible
depending on the value of the integer TPVIEW:
