Class UniformScalingShape

java.lang.Object
  com.bulletphysics.collision.shapes.CollisionShape
      com.bulletphysics.collision.shapes.ConvexShape
          com.bulletphysics.collision.shapes.UniformScalingShape

public class UniformScalingShape
extends ConvexShape

UniformScalingShape allows to re-use uniform scaled instances of ConvexShape in a memory efficient way. Istead of using UniformScalingShape, it is better to use the non-uniform setLocalScaling method on convex shapes that implement it.
