Evolutionary Morphing

Using the statistical framework of geometric morphometrics one can track the evolutionary changes within species. This image is taken from the system that tracks multiple points models of the skull of a family of monkeys, and the model is used to create

Visualization of Flow about an Ellipsoid

UC Davis researchers have pioneered the use of transparent surfaces to visualize flow. Transparent integral surfaces are used to visualize the formation of a horseshoe-shaped vortex system in the blow behind an ellipsoid. Christoph Garth, Hari Krishna

Plume-like Flow Structure

Visualization of a plume-like flow structure in a thermal convection flow. The streak surface, imbedded in the flow, is mapped with a texture that provides improved spatial perception of the surface, and hints at the direction of streaklines (left), and

Visualization of Flow Structures

A streak surface visualizes a plume-like flow structure in a thermal convection flow. The surface is generated from millions of individual particles that are advected by the flow. Christoph Garth, 2010

Vortex Breakdown Bubble

As a triangular-shaped aircraft descends through the atmosphere, the edges of its wings creates vortices, which eventually break down after the aircraft has passed. Frequently in the vortex breakdown, “bubbles” form, which have a very complex structure.

Visualization of a Jet Flow 1

Four timesteps are shown of a jet flow simulation illustrating the formation of turbulence in time-varying flows. Direct volume rendering of Finite-Time Lyapunov Exponents for forward (red) and backward (blue) advection illustrates the dynamical skeleton
