Here you can see the underlying trianglestrip structure. 6059b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * You will notice some off lines; these are degenerate triangles and are part of the 6159b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * trianglestrip. They are only noticeable in wireframe mode. 6259b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * Second is Tri-Planar texture mode. Here the textures are rendered on all 3 axes and 6359b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * then blended together to reduce distortion and stretching. 6459b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * Third, which you have to modify the code to see, is Entropy LOD calculations. 6559b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * In the constructor for the TerrainQuad, un-comment the final parameter that is 6659b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * the LodPerspectiveCalculatorFactory. Then you will see the terrain flicker to start 6759b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * while it calculates the entropies. Once it is done, it will pick the best LOD value 6859b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * based on entropy. This method reduces "popping" of terrain greatly when LOD levels 6959b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * change. It is highly suggested you use it in your app. 7059b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * 7159b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta * @author bowens 7259b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta */ 7359b2e6871c65f58fdad78cd7229c292f6a177578Scott Bartapublic class TerrainTest extends SimpleApplication { 7459b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta 7559b2e6871c65f58fdad78cd7229c292f6a177578Scott Barta private TerrainQuad terrain;
