Cartoon Water Rendering

The project is an implementation of modified Cartoon Water Rendering with Foam and Surface Smoothing[1] using OpenGL. And the physical simulation of liquid is based on Position Based Fluids[2] written in CUDA.

Run the Demo

keyboard shortcut

1. spacebar, Run the demo or Stop at some frame.
2. m, Sweep the box boundary or Stop the moving boundary.
3. And you can use mouse to adjust the camera’s position or direction.

Features

• Imcompressible fluids simulation based on PBD[2].
• Screen space surface reconstruction based on point splatting[3].
• Cartoon water rendering[1].
• GPU particle neighbor searching using Hash table[5].
