[ REQ 6281]: Rotations in Geomview
Dear Geometry Center Staff, I am a fourth year engineering student at the University of Virginia and I am developing an external module for Geomview which can be used to visualize the solutions to optimal control problems involving reorientation of objects. I have run into a small problem however because I can not figure out how Geomview calculates the rotation matrix from the supplied angles when more than one angle is given in a transform command, such as: (transform g1 g1 g1 rotate 0 -pi/2 pi/2) I had assumed that it would first perform the rotation about one axis and then the other but this is not the case. Also, I have noticed that once a command file is read in there is no wat to stop the execution of the commands. Is this true and if not, how does one go about terminating the execution of the commands without exiting Geomview? I thank you in advance for any time and consideration that you are able to devote to these questions. Sincerely, Felix Galbis-Reig
