There are many flavors of VR integration libraries out there to abstract away the immersive display hardware; the Wikipedia CAVE page lists many of them under software. Most of them will do just fine for immersive visualization, but if you are new and need to pick one or just want a change, take a look at Oliver Kreylos’s VRUI. He has built numerous immersive vis applications on it at UC Davis. INL, DRI, and Indiana U. also build scientific visualization applications with VRUI.
What do we like about it? It seamlessly spans from desktops to tiled display walls to CAVEs. Many VR libraries have a desktop simulator mode, but few provide both a true desktop user experience and a fully-fledged immersive interface without burdening the application programmer to design both.
