bounding box....

[giancamati]

Hello everybody, due to my ignorance in programming with Vizard I am trying to visualized the bounding box of a picked object. I wish to visualize it in red. I tryed with the following gode:
pickedOBJ = viz.pick()

if pickedOBJ.valid():
print 'Oggetto CATTURATO'
if pickedOBJ == box:
box.color(viz.BLUE)
box.link(FlockBirds)
box.get(viz.BOUNDING_BOX).visible(1)
box.get(viz.BOUNDING_BOX).color(viz.RED)

Is that right?
Thank you.

Here is some code that visualizes a bounding box.


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 )
