DEFINITION OF A 3D VIEW FROM XY PLANE
CALL SEQUENCE
void tview3_xy_plane (wkid, view_ind, pointc, view_type, zoom, viewport)
INPUT PARAMETERS
Pint wkid;
Pint view_ind;
Ppoint3 *pointc;
Pint view_type;
Pfloat zoom;
Plimit3 *viewport;
ARGUMENTS
- wkid
- Identifier of the workstation on which the view is defined.
- view_ind
- Index of the view to be defined.
- pointc
- Coordinates (in normalized space [0-1] × [0-1] × [0-1]) of the
point of the scene concerned.
- view_type
- 1 to 8: eight types of view on the plane XY are possible
- zoom
- Zoom factor applied to the image.
- 1: the image is normal
- 2: the image is magnified by two
- 0.5: the image is reduced by 2
- etc...
- viewport
- Viewport (see tview_config).
EFFECT
This function defines the view identified by the integer view_ind. The
observer looks toward the point pointc 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 view_type:
