SnugBlur!: Contraint-Preserving Motion Blur

Many renderers compute motion blur linearly, which can produce artifacts when an object nonlinearly moves near another. For instance, an eyelid intersects an eyeball during a blink motion. This talk presents constraint-preserving motion blur, which allows us to selectively correct complex motion paths while preserving the linear simplicity of others.

Pencil-Tracing Mirage: Principle and its Evaluation

A method of simulating various mirages in 3D CG. Mirages are caused by the fluctuation of the refractive index of the air. This talk focuses on the pencil-tracing technique and how it replicates the fluctuating appearance of mirages by introducing a perturbation component.

Discrete Texture Design Using a Programmable Approach

This talk considers discrete textures as programs that place points, curves, and regions. The programs are based on an operator set that factorizes redundant concepts shared by classic element-distribution algorithms. This programmable approach is able to represent and produce a wide diversity of textures.
