anchor.diff:  == Pick Reduction Methods and Values
   
   There are several reduction methods to generate a low-polygon version from a high-polygon model. Don't worry, the reduction does not modify the original model.

negative.code: 
  One solution for this problem is to use high-detail meshes for objects close to the camera, and low-detail meshes for objects far from the camera. As the player moves through the scene, you must keep replacing close objects by more detailed meshes, and far objects by less detailed meshes. The goal is to keep few high-quality slow-rendering objects in the foreground, and many low-quality fast-rendering objects in the background. (Experienced users can compare this approach to <<jme3/advanced/terrain#,JME's TerraMonkey terrain system>>, which internally uses the specialized GeoMipMapping algorithm to generate a terrain's Levels of Detail.)
  
  You see now why you may want to be able to generate Levels of Detail for complex Geometries automatically. JME3 supports a Java implementation of the Ogre engine's LOD generator (originally by Péter Szücs and Stan Melax): You use link:{uri-jme3}/jme3-core/src/tools/java/jme3tools/optimize/LodGenerator.java[jme3tools.optimize.LodGenerator] in conjunction with link:{uri-jme3}/jme3-core/src/main/java/com/jme3/scene/control/LodControl.java[com.jme3.scene.control.LodControl].
  
  For a demo, run link:{uri-jme3}/jme3-examples/src/main/java/jme3test/stress/TestLodGeneration.java[TestLodGeneration.java] from <<sdk/sample_code#,JmeTests>>, then press +/- and spacebar to experiment. The following screenshots show a monkey model with three reduced Levels of Detail:
