1. Smoke simulation without obstacles

2. Smoke simulation with a ball obstacle

3. Vortex ring preservation even at coarse grid resolutions

4. Smoke simulation over a tube with a complex shape

5. Comparisons of smoke simulations with the unconditionally stable MacCormack scheme (a) & (d) and recent work of Zhang et al. [SIGGRAPH 2015; SIGGRAPH 2016] (b) & (e)

6. Comparison of smoke simulations between high resolution unconditionally stable MacCormack scheme (top) and our method (bottom)

7. Comparison of flows passing through a ball with different resolutions and sample placement: (a) uniform grid with high resolution; (b) our adaptive resolution with much less number of samples; (c) uniform grid with low resolution
