KinematicState.Transform
Returns or sets the transformation (SITransformation) of an object.
Currently you cannot set the tranform at a different time than the
current time. To cause the transformation to change over time you
should animate the parameters of the KinematicState object.
Note: This property is not Python-compliant because Python does not
support input parameters on properties. Use KinematicState.GetTransform2
and KinematicState.PutTransform2
instead.
Warning: The returned SITransformation object contains a copy of
the transformation values, so modifying its state will have no
effect on the original object. To change the object's kinematic
state you must set this property with the modified SITransformation
object, as shown in the example below.
// get accessor Object KinematicState.get_Transform( Object inFrame ); // set accessor KinematicState.set_Transform( Object inFrame, Object out_ppRetVal ); |
| Parameter | Type | Description |
|---|---|---|
| Frame | Variant | Frame at which to get the transform. |
/*
This example shows how to modify the state of a transform
when you are working on a copy of the object.

// Warning: you cannot change the object's transform like this:
// oCube.Kinematics.Local.Transform.SetMatrix4(oMat4);
// because this will only modify a copy of the transform object
// not the real state of oCube.Kinematics.Local.Transform
oTrans.SetMatrix4(oMat4);
// Replace the transform with the modified copy
oCube.Kinematics.Local.Transform = oTrans;
