Symplectic ray tracing presents a new technique for visualizing curved black-hole spacetime. Efficient computation for CG based on the ray tracing is realized by using Hamilton's canonical equation with symplectic numerical analysis.

In response to growing concern about non-photorealistic rendering, this sketch proposes a colored-paper mosaic-rendering technique that can automatically generate torn and tagged colored-paper mosaic effects.

Shading in line drawings is expressed by varying stroke width or density of strokes. This new method can do it either way, introducing lighting-dependent surface detail to interactive NPR.
