Tips and Tricks

When setting up CaveUT, try turning off spectator mode, turn on the HUD and make sure the crosshairs are visible. The crosshairs mark the vanishing point of the screen image. Use that for calibrating your off-axis projections and/or view rotations.

Instead of the crosshairs for targeting, which are turned off in CaveUT, tape a penny or similar marker onto the screen where the weapons fire is focused. In a typical two-walled V-Cave, this is about two-thirds of the way up from the bottom along the central seam.

One of the things about CaveUT that amazes many programmers familiar with multiscreen displays is that CaveUT makes no attempt to synchronize the updates in the multiple screens, commonly known as "genlock". Each screen just updates as fast as it can. As long as all the screens can update at 30 frames per second or faster, the viewer will never notice. If performance begins to lag, however, there will often be situations where one screen has updated because the view moved or rotated, but another did not, causing a visual disconnect between the two screens. In practice, this will not be a problem as long as the machines are offering fast performance. (Note that genlock is required for stereoscopic displays, and CaveUT/UT2004 is not yet stereoscopic.)
