Here is some code that visualizes a bounding box.
Code:
import viz
import vizact
viz.go()
viz.clearcolor(viz.SKYBLUE)
box = viz.add( 'box.wrl' )
box.alpha( .2 )
box.color( viz.RED )
def drawborder(obj ):
savedEuler = obj.get( viz.EULER )
obj.rotate( 0, 0, 0 )
bb = obj.get( viz.BOUNDING_BOX, viz.RELATIVE_LOCAL )
obj.rotate( savedEuler )
box.translate( bb[3:7] )
box.rotate( obj.get( viz.EULER ) )
box.scale( bb[0:3] )
logo = viz.add( 'logo.wrl' )
logo.add( vizact.goto( 0, 0, 10, 10 ) )
logo.add( vizact.spin( 0, 1, 0, 45, viz.FOREVER ), 1 )
def onTimer(num):
drawborder( logo )
viz.callback(viz.TIMER_EVENT,onTimer)
viz.starttimer( 0, 0, viz.FOREVER )
