I am using GRASS 4.1 and SG3d, and I am wondering if when displaying 3D images one can zoom in to different aspects of the image. If so, how do you do it? If not, does GRASS 4.1 have any type of zooming capabilities (outside of SG3d)? Thanks Cristian Santesteban Applied Research Laboratories UT Austin cjs at ccwf.cc.utexas.edu
