Instant Volumetric Understanding with Order-Independent Volume Rendering
Rapid, visual understanding of volumetric datasets is a crucial outcome of a good volume rendering application, but few current volume rendering systems deliver this result. Our g...

Reductions in Circuit Complexity: An Isomorphism Theorem and a Gap Theorem
We show that all sets that are complete for NP under non-uniform AC0 reductions are isomorphic under non-uniform AC0-computable isomorphisms. Furthermore, these sets remain NP-com...

Threshold Dominating Sets and an Improved Characterization of W[2]
The Threshold Dominating Set problem is that of determining for a graph G = (V, E) whether there is a subset V ⊆ V of size k, such that for each vertex v ∈ V there are at leas...

GPU Accelerated Direct Volume Rendering on an Interactive Light Field Display
We present a GPU accelerated volume ray casting system interactively driving a multi-user light field display. The display, driven by a single programmable GPU, is based on a spec...
