They share the property that in each technique, the speed of the camera position through the enviornment is a function of the range of the camera to objects in the scene. The question I'm asking is: does anyone know of anything else that does this, or anything remotely similar? I've done due diligence with a search of the ACM library, and now I'm asking the crowd if they know of anything. -- Matt ___________________________________________________ Matt Conway User Interface Research Group Microsoft Research http://www.research.microsoft.com/~mconway/ -----Original Message----- From: Kevin Curry [mailto:kcurry@csgrad.cs.vt.edu] Sent: Tuesday, February 23, 1999 9:26 PM To: Matt Conway Cc: 3D UI List (E-mail) Subject: Re: hi all i'm a little unclear about your request, but it sounds like your first thing is about what i refer to as "camera positions" and your second thing seems to be either about level-of-detail (LOD) or flying navigation. both cameras and LOD are key features in graphics packages like OpenGL and Performer and are thus covered in the documentation (you'd probably want the Programmer's Guide for each). flying and navigation are the subjects of stuff like saranav and pfNav. saranav is at http://www.sara.nl/hec/vr/cave/software/saranav.html , but i don't think it's what you want. Do you have access to the ACM Digital Library?
