Volume Deformation via Scattered Data Interpolation (2008)
H. C. Hege, R. Machiraju (editors, Carlos D. Correa, Deborah Silver, Min Chen
With the advent of contemporary GPUs, it has been possible to perform volume deformation at interactive rates. In particular, it has been shown that deformation can be important for the purposes of...
Discontinuous Displacement Mapping for Volume Graphics (2008)
T. Möller, R. Machiraju, T. Ertl, M. Chen (editors, Carlos D. Correa, Deborah Silver, ...
Figure 1: Four temporal steps in which a dynamic discontinuous displacement map is applied to a piggy bank object interactively to simulate a cutting effect. Displacement mapping is commonly used for...
Visualizing Collision Effects between Penetrating and Non-Penetrating Objects (2008)
Carlos D. Correa, Deborah Silver
We present a novel method for visualizing collisions effects between penetrating or non-penetrating objects. The interaction of 3D objects has been traditionally divided into two stages: the detection
A Simplification Architecture for Exploring Navigation Tradeoffs in Mobile VR (2007)
Interactive applications on mobile devices often reduce data fidelity to adapt to resource constraints and variable user preferences. In virtual reality applications, the problem of reducing scene...
Collaborative virtual environments with heterogeneous computing resources and user preferences often reduce data fidelity to accommodate such heterogeneity. Given the resource limitations and user...
D. Correa, Prof Deborah Silver, Carlos D. Correa, Carlos D. Correa, Dissertation Director, Prof Deborah Silver
The purpose of visualization is to gain understanding of 3D structures through images. Al-though many rendering techniques have been proposed for this purpose, the effective visual-ization remains a...
Feature aligned volume manipulation for illustration and visualization (2006)
Carlos D. Correa, Student Member, Deborah Silver, Min Chen
Abstract—In this paper we describe a GPU-based technique for creating illustrative visualization through interactive manipulation of volumetric models. It is partly inspired by medical...
Exact and Heuristic Algorithms For Dynamic Tree Simplification (2004)
Carlos D. Correa, Xiaodong Sun, X. Sun, Ivan Marsic
The Tree Knapsack Problem (TKP) is a 0-1 integer programming problem where hierarchy constraints are enforced. If a node is selected for packing into the knapsack, all the ancestor nodes on the path...
