Class QuantizedBvhNodes

java.lang.Object
  com.bulletphysics.collision.shapes.QuantizedBvhNodes

All Implemented Interfaces:

Serializable

public class QuantizedBvhNodes
extends Object
implements Serializable

QuantizedBvhNodes is array of compressed AABB nodes, each of 16 bytes. Node can be used for leaf node or internal node. Leaf nodes can point to 32-bit triangle index (non-negative range).

Implementation note: the nodes are internally stored in int[] array and bit packed. The actual structure is:

 unsigned short  quantizedAabbMin[3]
 unsigned short  quantizedAabbMax[3]
 signed   int    escapeIndexOrTriangleIndex
