Abstract
This paper proposes a sampling technique to create a slice image with opacity to render the same volume. Our method is based on the particle-based rendering, which uses tiny particles as rendering primitives. In this research, three sampling methods are proposed for applying opacity: (1) Metropolis sampling of the whole plane, (2) Uniform sampling at each grid, (3) Metropolis sampling at each grid. The results show that the borderline is clearly shown in the low-opacity area using technique 2 and is clearly shown in the high-opacity area by using technique 3.
