I and @agnesheyer made a demo recently running on Android @VulkanAPI, some tech features:
- Bandlimited pixel art filtering (http://themaister.net/blog/2018/08/25/pseudo-bandlimited-pixel-art-filtering-in-3d-a-mathematical-derivation/ …)
- Volumetric fog (AC IV-style, compute)
- Multi-layer refraction
- Ocean FFT (compute, Tessendorf style)https://www.youtube.com/watch?v=iw6hfZj8TFg …
My complaint is it needs more scenes, it suffers from a lack of content. The tech is nice tho.
