Image Warping
 

Do you need to use image warping software if you wanna project your Vizard program on a screen? Does Vizard have a built in function for it?

If you want the projected image to change based on a tracked user and their position relative to the screen use the vizcave library. If you want to blend images from multiple projectors or warp the image to to fit a display surface (e.g. curved) then you would need 3rd party software to do that.

Also, vizconnect has CAVE and powerwall options in the display tab of the advanced configuration menu that generate the vizcave code for you.
