I did a lot of mouse interaction stuff in gem, although only 2d, because 3d needs depth test, which I avoided until now. but yes, it is always a lot of translations. I have some objects that do mouseover detection on circles and rectangles and options to drag them around whithout. I think pdmtl has some of that, too(?). basically these are separate objects that can be hooked up to shapesand control the interaction. do you want me to post them? marius. > > > > > Am 03.09.2008 um 18:08 schrieb marius schebella: > >> hi, >> after fuzzing around with 3d to pix conversions for the xth time, I >> thought it should also be possible to set the camera to a point that >> just allows to have all units in pixels with the 0/0 in the top left >> corner. >> the only way to get this working was to set the camera to a negative z >> position and flip the upvector. the problem with that is, that all >> images will be vertically flipped, too. >> so I wonder whether there could be a general gemwin switch to flip + >> and - on the y axis? >> and again, it would be extremely cool to have a possibility to read >> out the curent size of the gemwin. >> thanks, >> marius.<camera_pixel_view.pd>_______________________________________________ >> >> [email protected] mailing list >> UNSUBSCRIBE and account-management -> >> http://lists.puredata.info/listinfo/pd-list > _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
