jme3test.terrain.TerrainTest

All Implemented Interfaces:

Application, SystemListener

public class TerrainTest
extends SimpleApplication

Demonstrates how to use terrain. The base terrain class it uses is TerrainQuad, which is a quad tree of actual meshes called TerrainPatches. There are a couple options for the terrain in this test: The first is wireframe mode. Here you can see the underlying trianglestrip structure. You will notice some off lines; these are degenerate triangles and are part of the trianglestrip. They are only noticeable in wireframe mode. Second is Tri-Planar texture mode. Here the textures are rendered on all 3 axes and then blended together to reduce distortion and stretching. Third, which you have to modify the code to see, is Entropy LOD calculations. In the constructor for the TerrainQuad, un-comment the final parameter that is the LodPerspectiveCalculatorFactory. Then you will see the terrain flicker to start while it calculates the entropies. Once it is done, it will pick the best LOD value based on entropy. This method reduces "popping" of terrain greatly when LOD levels change. It is highly suggested you use it in your app.

initialize

public void initialize()

Description copied from class: LegacyApplication

Do not call manually. Callback from ContextListener.

Initializes the Application, by creating a display and default camera. If display settings are not specified, a default 640x480 display is created. Default values are used for the camera; perspective projection with 45° field of view, with near and far values 1 and 1000 units respectively.
