How to control ive or osg animation?

Dear All

The animation I exported from 3DSmax into ive files run in vizard loop mode. How can I control that animation?

I would need to pause/ slow down or speed it up.

Many thanks in advance.

There are a number of get and set commands that can be used with imported animations. The following example shows how to set the speed, state, and loop mode on one of the animations included in the piazza_animations.osgb file:

Code:

import viz

import vizact

viz.go()



viz.setMultiSample(8)

viz.fov(60)

viz.go()



# Add piazza model

model = viz.addChild('piazza.osgb')

# Add piazza animations

animations = viz.add('piazza_animations.osgb')



# Create avatar parented to walk animation

avatar_path = animations.getChild('walk')

avatar = viz.addAvatar('vcc_male2.cfg')

avatar.setParent(avatar_path,node='walk')

avatar.state(2)



#set animation time, speed, and loop mode

avatar_path.setAnimationTime(10.0)

avatar_path.setAnimationSpeed(1.5)

avatar_path.setAnimationLoopMode(0)



#toggle between pause/play

vizact.onkeydown(' ',avatar_path.setAnimationState,viz.TOGGLE)

                

viz.MainView.move([0,0,-7])

Thank you Jeff!

I understand the script works only for osg animations. Is there a way to control animations on ive files?

It will work with ive. If you are exporting these models yourself we recommend exporting to osgb, the newer and preferred version of the compiled osg format.
