Lines: 21 We are trying to use the "mapw" command to transform a selected position (X,Y) on the screen into world coordinates(x,y,z). We have no problem getting the X,Y coordinates without calling mapw, but can't seem to make mapw return the correct line. We think the problem lies in the multiple transformations(rotations, zooms, translations) that the system can undergo and that these transformations somehow distort the view Any help would be greatly appreciated. Please respond directly via e-mail to: dmz@rutile.rutgers.edu Thanks in advance David Zirl Rutgers University Department of Ceramics (dmz@rutile.rutgers.edu)
