Good morning everybody Working daily with anaglyph images for geological/geomorphological analysis on stereo images obtained from high/very-high resolution satellite images, I'm searching for a solution to avoid to use the classic red/blue glasses. Looking at an alternative solution I've found the 3D glasses NVIDIA (http://www.nvidia.com/obj...ion-home-users.html) that coupled with a dedicate hardware (shutter glasses, 120Mhz screen...) allow to see in 3D without stressing the eyes. Unfortunately there is no drivers (produced by NVIDIA) compatible with ITTVIS Software that allow to use this hardware with ENVI ZOOM or ENVI (here is the list of softwares compatible with this system: http://www.nvidia.com/pag...ified_drivers.html). There is someone in this forum that has experience in this domain and suggest me some solutions? Thank you very much for any help. Enrico Bonino Dr. Senior GIS/Remote Sensing Specialist KEYOBS SA
