Camera Position And Viztask
 
Hi,

I have a simple script that makes the camera move forward in my scene. The camera moves through some balls. Now I want to accomplish a task every time the camera's position surpasses the ball's.

I use the following lines to move the camera:

Code:

class AmblioCameraHandler( viz.CameraHandler ):
        def _camUpdate( self, e ):
                e.view.move( 0, 0, speed)


Nextly, I need to get the cameras position by doing:

Code:

cam_pos = viz.MainView.getPosition()
And then I need to compare it with the ball's z coord.

How can I do that using this viztask method?

Best regards!

You can create you own custom condition that checks the position of the viewpoint in relation to the balls. The following page has a section on writing a viztask condition:
