v4.0
Uses two guide objects to create a two-point slide setup. A two-point slide setup consists of 'Bind' object and two control objects, 'Top' and 'Base' that control the Bind object by a two point constraint. Optionally the orientation of the Bind object can be controlled with an upvector, and constrained to avoid an implicit volume object (bounding volume).
oPointSlide = Make2PointSlide( [Prefix], GuidePoint1, GuidePoint2, Parent1, Parent2, [UpVector], [BoundingVolume] ); |
Returns a PointSlide JScript object.
Parameter | Type | Description |
---|---|---|
Prefix | String | The name prefix for the newly created slide nulls. |
GuidePoint1 | String | 3D Object, whose pose will be assumed by the first slide object. |
GuidePoint2 | String | 3D Object, whose pose will be assumed by the second slide object. |
Parent1 | String | The parent under which the first slide object will be placed. |
Parent2 | String | The parent under which the second slide object will be placed. |
UpVector | String | An upvector object to control the orientation of the Binding Point. |
BoundingVolume | String | A bounding volume implicit to stay outside of when sliding. |
