View Control Window

The View Control Window may be used to modify components of the viewing-reference coordinate system and the view volume. These changes, when applied, are reflected in both the World and View Window Panels.

The following values may be modified

• VRP: The viewing-reference point, shown in WC (world coordinates).
• VPN: The normalized view-plane normal, shown in WC. Adjusting one component will affect the others because the vector is normalized. For example, if the VPN was (0, 0, 1) and its X-value was changed to 1, the VPN would be set to (.707, 0, .707), which is the normalized value of the vector (1, 0, 1).
• VUP: The normalized view-up vector, shown in WC. Adjusting one component will affect the others because the vector is normalized.
• PRP: The projection reference point, shown in VRC (viewing-reference coordinates).
• VW min: The view window minimum point, shown in VRC. Only the U and V components are valid since the view window is a two-dimensional window that exists in the UV plane of the VRC.
• VW max: The view window maximum point, shown in VRC. Only the U and V components are valid since the view window is a two-dimensional window that exists in the UV plane of the VRC.
• F clip: The front distance, shown in VRC. Only the N component is valid since the distance is a one-dimensional measurement along the VPN.
• B clip: The back distance, shown in VRC. Only the N component is valid since the distance is a one-dimensional measurement along the VPN.

More than one update may be made at once. All the changes will be applied when the Apply Updates menu item is selected.
