• VolQD system : tool for the analysis of QD electron wave functions - volume view and slice view for scientist
  • Requirements
    • Functions
      • Muilti-field : the capability of rendering multiple electron orbitals
      • Statistics : volume view and slice view
        • the number of percentage of the atoms with one or more orbitals satsfying certain criteria
        • the percentage contirbutions of orbitals to the total electron cloud
    • Non-functional requirements
      • Scalability : Effective memory management
      • Interactivity (Performance)

  • Approach
    • representing FCC lattice based on BCC reconstruction scheme
      • Optimal regular volume sampling
      • Footprint evaluation for volumn rendering
      • Linear and cubic box splines for the body centered cubic lattice
    • Cell projection
      • used texture-based volume rendering approach base on Westermann and Ertl's work for interactive rendering of multi-million atom simulations
      • FCC lattices can be compactly represented in local graphics memory using 3D-texture
      • the lattices geometry is not required for geometry
      • straightforward implementation with custom reconstruction filters can be achieved using programmable GPU
  • Detail Approach
    • Preprocessing
      • conversion of raw simulation data into binary texture data
    • Texture Representation
      • Texture Representation is a extension of BCC grids (Texture based volumn rendering of hexagonal data sets) <- I couldn't find it
    • Reconstruction Filters
    • Transfer function
      • Transfer functions on a logarithmic scale for volumn rendering
    • Multi-field Visualization
      • a channel per atranfser function is assigned
