webgl-dunes VS LayaAir

To examine how objects are rendered, you can take a look at drawScene() method in DunesRenderer.ts — first we render depth map to texture (this is needed for soft particles), then render on-screen objects in front-to-back order (first closest and largest objects, then distant) to efficiently utilize z-buffer culling. Terrain in the scene is represented as a single square tile. Its polycount is reduced to 31k faces in order not to split geometry and to draw it with a single draw call. This polycount produces a reasonably good quality. However, its area is not quite large enough to create a feel of infinite sand desert — when the camera is placed slightly above terrain boundaries of square terrain its limits are clearly visible:
