Animating an out-of-body transition
greetings!
I would like to construct an animation that swings the viewport around to look at the avatar representing the person who is looking through the viewport while moving away to a pre-determined position external position, a sort of an out-of-body experience. Currently I am trying to achieve this by using the commands: <viewpoint>.goto(x,y,z,vel) and <viewpoint>.lookat(x,y,z) my actual code looks like this: def outofmymind(): # animate a smooth POV transition global myAvatar myApos = myAvatar.get(viz.POSITION) myPOV = viz.get(viz.MAIN_VIEWPOINT) myPOV.lookat(myApos) myPOV.goto(5,5,5,.85) #just an arbitrary external place however, instead of going to (5,5,5) in about 2 seconds while looking at myAvatar, the viewport just sinks down (-y) any comments on my (apparently wrong) code and any suggestions for improvement are very appreciated. Thanks! btw, what formatting do you use especially for code, and how do I access it from "post new thread" webpage (is it in enhanced mode?) |

Hi,
Take a look at the <viewpoint>.gotomode and <viewpoint>.pivot commands. Also, there is an example script in the [Vizard20]/examples/advanced directory called animateview.py which shows how to use these functions. Basically what you would want to do is something like the following: Code:
def outofmymind(): # animate a smooth POV transition myApos = myAvatar.get(viz.POSITION) myPOV = viz.get(viz.MAIN_VIEWPOINT) myPOV.gotomode(viz.BLEND_ROTATE) #Also try out viz.PIVOT_ROTATE, see which one you like better myPOV.pivot(myApos) myPOV.goto(5,5,5,.85) #just an arbitrary external place |

works great! thanks
I found that the BLEND_ROTATE feels more natural, as much as an out-of-body experience can feel natural.
thanks again! |
