How to calculate a distance between a moving Avatar and the viewpoint?
Dear smart Forum member,
I need to calculate the distance between the position of Avatars, moving from waypoint to waypoint, and the position of the user. At the end of each trial, the minimum distance between viewpoint of the user and avatar at any given time point of the trial should be printed out. I got this far in regard of calculating the distance towards a stable object (at 0.4, 1.8, 0; in this case): ------------------------- # Globals pos = [] minDist = 10000 posModel = [0.4,1.8,0] #euklidische Distanz def dist(posModel): global minDist pos = viz.MainView.getPosition() dist = [(a - b)**2 for a, b in zip(pos, posModel)] dist = math.sqrt(sum(dist)) if dist < minDist: minDist = dist print minDist print dist vizact.ontimer(0.1,dist, posModel) def quit(): global minDist print minDist viz.quit() vizact.onkeydown('q',quit) ------------------------ My problem: How do I get the position of Avatars, while they are moving from waypoint to waypoint? Is there a way to get the Position of moving avatars similar to "viz.MainView.getPosition()" for the Position of the user? Best, John |
