Relations > Bounding constraints > Bounding sphere

Bounding sphere


This relation is identical to bounding box but uses a sphere, determined by a radius. It creates an invisible sphere within which the selected object must remain. An object could therefore be moved around by users but only within a certain radius.


To create a bounding sphere constraint:
  1. Multi-select the object that you want to constrain and then an object to serve as a bounding sphere, in that order.
  2. Choose Relations > Bounding Constraints > Sphere.
  3. Scale the sphere to the appropriate size and toggle off its visibility.

Bounding Sphere Parameters

Active

Toggles the constraint on and off.

Weight

Determines the weight of this constraint in relation to other constraints acting on the same object.

Inside

Constrains the object to stay inside the sphere. If Inside is turned off, the object cannot enter the sphere.

Geometry constrained

Uses the object's outer geometry as limits when calculating the bounding sphere. When this option is on, a sphere appears around the constrained object, and it is the outer radius of that sphere that determines when the object has reached its limit. When Geometry constrained is off, the object's center serves as a reference.
