DEFINITION OF A PARALLEL 3D VIEW - Y AXIS VERTICAL
CALL SEQUENCE
void tview3_paral_y_vert (wkid, view_ind, pointc , phi, teta, zoom, viewport)
INPUT PARAMETERS
Pint wkid;
Pint view_ind;
Ppoint3 *pointc;
Pfloat phi;
Pfloat teta;
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.
- phi
- Angle phi around the Y axis, expressed in degrees.
- teta
- Angle teta expressed in degrees.
- 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, the orientation given in
spherical coordinates, phi and teta, in relation to the Y
axis. The projections used by the view thus defined are in parallel.
