Unable to move from one scene to another in Vizard?
Dear all
Could you please help me with the following items? I face some issues on the following: 1. I have four scenes in which, I will have to have a multiple choice questions at the end of each scene. After pressing enter, it should go to Scene 2, followed by multiple choice questions. It should continue for the all the four scenes. Could anyone please help me with this? How can I do it? Thanks, BS |

Take a look at the viztask module. That will help with setting up the program flow. You can wait for a button event before changing the scene. The designing an experiment tutorial uses a GUI and waits for a button event.

Hi saravanan.balak,
You just need to use the below code to switch between viewpoints by loading and removing the appropriate models at runtime. Beelow is the code for switching between 2 viewpoints but only one single (you can use 2 models and load and remove/unload at runtime and changes the view points. Code:
import viz import vizact import vizconnect import viztask # start the vizconnect session stored in the given directory vizconnect.go("vizconnect_config.py") # oriMode sets what the viewpoint is resetting to. For example... # vizconnect.VIEWPOINT_MATCH_DISPLAY # matches orientation of the display to the orientation of the viewpoint # # vizconnect.VIEWPOINT_MATCH_FEET # matches orientation of the feet to the orientation of the viewpoint # # vizconnect.VIEWPOINT_MATCH_BASE # matches orientation of the base object (transport, avatar, tracker) to the orientation of the viewpoint # # Similar for posMode oriMode = vizconnect.VIEWPOINT_MATCH_DISPLAY posMode = vizconnect.VIEWPOINT_MATCH_FEET # Add a viewpoint. vp1 = vizconnect.addViewpoint( pos=[-13.24803, 12.28260, 8.83578], euler=[90, 0, 0], posMode=posMode, oriMode=oriMode, constant=False, ) vp2 = vizconnect.addViewpoint( pos=[-17.24803, 4.28260, 5.83578], euler=[90, 0, 0], posMode=posMode, oriMode=oriMode, constant=False, ) # Displays are added to viewpoints, the viewpoint will traverse the scenegraph to # determine if the display is attached to an avatar, tracker, etc in order to # perform the requested resets. #vp1.add(vizconnect.getDisplay()) # add an environment viz.add('piazza.osgb') display = vizconnect.getDisplay() def viewTask(): while True: vp1.add(display) vizconnect.resetViewpoints() print'before 1st waitkeydown ' yield viztask.waitKeyDown(' ') vp1.remove(display) vp2.add(display) vizconnect.resetViewpoints() print'before 2nd waitkeydown ' yield viztask.waitKeyDown(' ') vp2.remove(display) viztask.schedule( viewTask() ) Mr.Rajnish Vishwakarma Last edited by rajnishv; 02-15-2018 at 08:31 AM. |
