      Manousopoulos, Polychronis; Drakopoulos, Vassileios; Theoharis, Theoharis (The Eurographics Association, 2008)
      Visualization of medical or experimental data is often achieved by extracting an intermediate geometric representation of the data. One such popular method for extracting an isosurface from volume data is the Marching Cubes ...
    • Volume Deformation via Scattered Data Interpolation 

      Correa, Carlos D.; Silver, Deborah; Chen, Min (The Eurographics Association, 2007)
      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 illustration. In such ...
    • Volume Deformations in Grid-Less Flow Simulations
