Contents

To do

  • multi-volume support
    • user interface - need to be able to manipulate one volume at a time
    • mesh generation - generating a mesh for multivolumes under one constraint - memory size
    • rendering - multi-volume rendering
      • new rendering algorithm: need to manage multi bricks overlaps with several bricks!
    • new class structures? like in virvo/multirend
    • time-series multivolume rendering - need to handle multi timesteps
  • brick prefetching for multi volumes
  • change # of slices according to brick size, the larger a brick, the more slices. - we're already doing this, figure out why there's intensity difference
  • Modify downsampler
    • buffered read/write
  • bytesPerChannel
  • parameterization of meshing constant
  • XML configuration - wait for Jurgen to ask whether or not covise system has its own parser. If not, I'll use any of opensource xml parsers, which support DOM spec.
  • svn commit for new vvGLSL
