Subject: Re: fixed / rotating origin Sender: dan.vera@gmail.com 18.06.09 02:32 Hi m a r c o , Thanks a lot for the reply (and the solution) and sorry for the late answer. Few additional things I found out: - if you use a direct routing the origin effectively rotate opposite to the object in the scene, so you have to change the sign of the rotation angle (cf code) - if you place the origin in a corner of the screen then the center of rotation changes, the scene is a bit awkward to navigate. by using the navigationinfo node, the center of rotation can be reset to 0 0 0 (or else).

I have managed to make a fixed "user panel" using the following code, but I cannot make it rotate and stay at the same place: #VRML V2.0 utf8 DEF PROXSENSOR ProximitySensor {size 1e8 1e8 1e8} DEF my_tra Transform {     children [     DEF my_pnl Transform {     translation 0 -1 -6.2      children [         DEF my_geo Shape {          geometry Box {          size 0.2 0.5 0.1          }      }      ]     }     ] } ROUTE PROXSENSOR.position_changed TO my_tra.translation ROUTE PROXSENSOR.orientation_changed TO my_tra.rotation If anyone has a idea/solution, i'd appreciate. thkx   [reply] [back to forum] [new message] [all forums] fixed / rotating origin / dan.vera@gmail.com / 4.06.09 16:25      Re: fixed / rotating origin / zlonka@gmail.com / 15.06.09 20:49          Re: fixed / rotating origin / dan.vera@gmail.com / 18.06.09 02:32 Messages in thread: 3 [reply] [back to forum] [new message] [all forums]
