3d viewpoint movement
I just tried the script for R2.5 as shown below which was given by Farshid, but it doesn't work with R3. Could anyone tell what's wrong with it, please?
import viz viz.go() #Add a ground viz.add('tut_ground.wrl') #Get main viewpoint object view = viz.get(viz.MAIN_VIEWPOINT) #Create a variable that will tell whether viewpoing is currently moving/turning view.animating = 0 #Variable that holds current destination value final = [0,0,0,0] def rotateview(x,y,z,angle): #Make sure view is not animating if not view.animating: #Compute rotation of turning body 90 degrees to right xform = viz.Transform(view.get(viz.BODY_MAT)) xform.preRot(x,y,z,angle) final[:] = xform.getRot()[:] #Start animating viewpoint view.spinmask(viz.BODY_ORI) #Spin the body orientation view.spinto(final,2,viz.TIME) #Spin for 2 seconds view.animating = 1 def onkeydown(key): if key == viz.KEY_UP: #Make sure view is not animating if not view.animating: pos = view.get(viz.HEAD_POS) trans = view.get(viz.BODY_LOOK) #Round values to nearest integer final[0] = int(round(pos[0] + trans[0])) final[1] = int(round(pos[1] + trans[1])) final[2] = int(round(pos[2] + trans[2])) #Start animating viewpoint view.goto(final,1,viz.TIME) view.animating = 1 elif key == '6': #yaw right rotateview(0,1,0,90) elif key == '4': #yaw left rotateview(0,1,0,-90) elif key == '8': #pitch up rotateview(1,0,0,-90) elif key == '2': #pitch down rotateview(1,0,0,90) elif key == '9': #roll right rotateview(0,0,1,-90) elif key == '7': #roll left rotateview(0,0,1,90) viz.callback(viz.KEYDOWN_EVENT,onkeydown) def onstop(object, type): if type == viz.MOVE: #Viewpoint is done moving, translate it to the final value just to be sure view.translate(final) view.animating = 0 elif type == viz.SPIN: #Viewpoint is done spinning, rotate it to the final value just to be sure view.rotate(final,viz.BODY_ORI) view.animating = 0 view.callback(viz.STOP_EVENT,onstop) |

I think you found a bug. The spin actions don't do anything when applied to the view.

SpaceBall
You may probably find that you have a similar error ("TypeError: spaceturn() takes exactly 2 argumemts (1 given)") when you use SpaceBall. I'd appreciate it if you could fix it. Thanks!

Thanks! It seems it works fine.
But when I use both SpaceBall and eMagin's HMD, only translation of SpaceBall input is working... |

Are you sure you haven't accidentally disabled rotations in the Spaceball Control Panel?

I guess so. I just add the following two lines to your script, and tested comment/uncomment them. When you uncomment them, the head tracker of the HMD works, but rotation of SpaceBall doesn't work. If you comment them, SpaceBall works in 6DOF.
--- visor = viz.add( 'eMagin.dls' ) viz.link( visor, viz.MainView ) --- |

The reason it doesn't work is because you are linking the emagin to the main view. So the rotations of the spaceball are being overridden by the rotations of the emagin.

Forgot to mention, if you want to use the spaceball together with the emagin, then replace viz.HEAD_ORI with viz.BODY_ORI in the spacerot function

That's the easiest solution! It works perfect!! Thanks a lot!!!
