Interactive LIC Visualization of Past Ocean Flow Patterns

Presenting "Ocean," an immersive ocean flow visualization application developed by a german visiting student, Rolf Westerteiger, during his stay at UC Davis as part of an NSF funded project on paleoceanography.

Flow patterns are generated from sedimentary core samples collected by Lorraine Lisiecki and graduate students of UC Santa Barbara, using a flow reconstruction method developed by Jake Gebbie of the Woods Hole Oceanographic Institution. The visualization application primarily uses a GPU-based implementation of real-time line integral convolution (LIC) to visualize the complex 3D patterns. Additionally, it can follow tracer particles injected into the flow, and can display the position and composition of all core samples that went into the flow reconstruction algorithm.

The visualization application is shown in UC Davis' KeckCAVES visualization environment, but the collaborators at UCSB and WHOI will be using low-cost visualization environments based on 3D TVs and optical tracking systems.
