In tonight's build there will be support for a viewpoint tag in ISL. You can do 3 things - set the aspect ratio of a view, set the tilt/azimuth (like you can do with the Viewpoint dialog) and explicitly set the rotation/translation/scale matrix. Attached is an example isl file that shows these 3 things. I have also added to the Aspect Ratio tab of the View manager properties dialog a listing of the rotation/scale/translation values. So you can easily figure out for a given viewpoint what the values are. Please give us some feedback on this and feel free to make suggestions for improvements. -Jeff Ticket Details =================== Ticket ID: EQX-211532 Department: Support IDV Priority: Normal Status: Closed
