Example 1 with LocationHeight

use of com.jme3.terrain.geomipmap.TerrainQuad.LocationHeight in project jmonkeyengine by jMonkeyEngine.

the class TerrainPatch method setHeight.

protected void setHeight(List<LocationHeight> locationHeights, boolean overrideHeight) {
    final float[] heightArray = geomap.getHeightArray();
    final VertexBuffer vertexBuffer = mesh.getBuffer(Type.Position);
    final FloatBuffer floatBuffer = mesh.getFloatBuffer(Type.Position);

        if (lh.x < 0 || lh.z < 0 || lh.x >= size || lh.z >= size) {
            continue;
        }
