Direct Ray Tracing of Displacement Mapped Triangles
We present an algorithm for ray tracing displacement maps that requires no additional storage over the base model. Displacement maps are rarely used in ray tracing due to the cost...

An Efficient Finite Element Method for Submicron IC Capacitance Extraction
We present an accurate and efficient method for extraction of parasitic capacitances in submicron integrated circuits. The method uses a 3-D finite element model in which the cond...

Elastically deformable models
Abstract: The theory of elasticity describes deformable materials such as rubber, cloth, paper, and flexible metals. We employ elasticity theory to construct differential equations...
