<viz>.addControlPoint

Adds a control point.

<viz>.addControlPoint(
pos = None
quat = None
euler = None
axisAngle = None
scale = None
)

pos = None

Optional position of control point

quat = None

Optional quaternion rotation of control point

euler = None

Optional euler rotation of control point

axisAngle = None

Optional axis-angle rotation of control point

scale = None

Optional scale of control point

Remarks

A control point is used in conjunction with AnimationPath. The object created here is a point along the animation path.

Return Value

<controlpoint> object

Example

ball = viz.addChild('beachball.osgb')
viz.MainView.setPosition([0,2,-8])

path = viz.addAnimationPath()

path.play()
path.setLoopMode(viz.CIRCULAR)
path.setAutoRotate(viz.ON)

positions = [ [0,0,2], [2,0,0], [0,0,-2], [-2,0,0] ]

for t,pos in enumerate(positions):
b = viz.addChild('beachball.osgb')
b.setPosition(pos)
b.alpha(0.2)
cp = viz.addControlPoint(pos=positions[t])
path.addControlPoint(t+1,cp)

viz.link(path,ball)
