Setting Up Data for Viewing
In some instances, you may need to set up your data for viewing before rendering. Several routines that set up viewing are:
*CENTER_VIEW—This procedure sets system viewing parameters to display data in the center of the current window.
*SET_VIEW3D—This procedure generates a three-dimensional view given a view position and a view direction.
*VIEWER—This procedure lets you interactively define a three-dimensional view, a slicing plane, and multiple cut-away volumes.
*T3D—This is a Standard PV‑WAVE library procedure. Refer to the PV‑WAVE Reference. This procedure is used by sphere_demo3, vec_demo1, vec_demo2, and vol_demo1. These demonstration programs are located in:
(UNIX) <wavedir>/demo/arl
(WIN) <wavedir>\demo\arl
This procedure is also used by the gen_ demonstration programs in:
(UNIX) <wavedir>/demo/render
(WIN) <wavedir>\demo\render
Where <wavedir> is the main PV‑WAVE directory.
