Filtering of half-float textures on different mobile GPUs
During development on PC everything was fine, but testing on different mobile phones with various GPUs revealed noticeable visual differences in hardware FP16 texture filtering. I suspect that the ANGLE wrapper for WebGL always uses full-precision floating point values in both shaders and textures, because we’ve already encountered precision issues in shader calculations during development of the Iceland WebGL demo - they were seen only on mobile devices with native WebGL-to-OpenGL ES translation.

Creating mountains landscape in OpenGL ES
Full source code is available on GitHub here and the live demo page is here. Click on the scene to change time of day (it may take a couple seconds to load textures), and by pressing Enter you can enter free-camera mode. Press and hold the right mouse button to look, and use WASD to move around.

Rendering dunes terrain in WebGL
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:
