Source Link

Document

Constructs and initializes a DistanceLOD node with the specified array of distances and the specified position.

Usage

From source file:SimpleLOD.java

/**
 * Build the content branch for the scene graph This creates three
 * cylinders, each with a different resolution. These are then used with a
 * LOD node to implement a crude level of detail.
 * //  w  ww .j a  v a 2s  . c  o m
 * @return BranchGroup that is the root of the content
 */
