Object Control Window - Objects and Viewing Parameters

The following objects are displayed in the World and View Window Panels. Note: An object will be identified by name in the Message Bar if the mouse is clicked on one of its vertices.

The (x, y, z) world-coordinate system, shown in the World Panel.

The model is seen in both the World Panel and, if it is visible given the current viewing parameters, the View Window Panel.

The viewing parameters create the view of the model displayed in the View Window Panel. They are displayed in the World Panel and may be examined and updated using the View Control Window. The viewing parameters include:

• The (u, v, n) viewing-reference coordinate (VRC) system, defined by the VRP, VPN and VUP.
• The view window, located in the VRC UV-plane. It has an initial width and height of 100, and its initial minimum point is set to the VRP.
• The PRP (Projection Reference Point).
• The front and back clip planes, which are visible if the View menu Show All View Components item is checked. The view volume is also outlined.
