示例1: computeLodEntropy
import com.jme3.scene.Mesh; //导入方法依赖的package包/类
public static float computeLodEntropy(Mesh terrainBlock, IntBuffer lodIndices){
// Bounding box for the terrain block
BoundingBox bbox = (BoundingBox) terrainBlock.getBound();
// Vertex positions for the block
FloatBuffer positions = terrainBlock.getFloatBuffer(Type.Position);
// Prepare to cast rays
Vector3f pos = new Vector3f();
Vector3f dir = new Vector3f(0, -1, 0);
Ray ray = new Ray(pos, dir);
// Prepare collision results
CollisionResults results = new CollisionResults();
// Set the LOD indices on the block
VertexBuffer originalIndices = terrainBlock.getBuffer(Type.Index);
terrainBlock.clearBuffer(Type.Index);
terrainBlock.setBuffer(Type.Index, 3, lodIndices);
// Recalculate collision mesh
terrainBlock.createCollisionData();
float entropy = 0;
for (int i = 0; i < positions.capacity() / 3; i++){
BufferUtils.populateFromBuffer(pos, positions, i);
float realHeight = pos.y;
pos.addLocal(0, bbox.getYExtent(), 0);
ray.setOrigin(pos);
results.clear();
terrainBlock.collideWith(ray, Matrix4f.IDENTITY, bbox, results);

Vector3f contactPoint = results.getClosestCollision().getContactPoint();
float delta = Math.abs(realHeight - contactPoint.y);
entropy = Math.max(delta, entropy);
}
}
// Restore original indices
terrainBlock.clearBuffer(Type.Index);
