#* the current downsampler does not pad empty data when a brick is not of a regular size. Nancy and I implemented in this way because it was easier than padding. However, this causes lots of problems from the reader part, mostly additional checking codelet whether a brick has a regular size, e.g. 128, or smaller than that. Due to the exception, we need couple more variables for boundary bricks of which size is usually smaller than the brick size. By padding, these inefficient and unnecessary data can be removed.

It would be good if we can reformat the configuration file with an XML schema, as we did in covise. A new format will affect downSampler*D, meshRend::loadConfigFile() and requires a new interface to pass the information between classes.

Multi volume support

  • For now, it can load multiple volumes but the algorithm used here is very simple: overlaying two rendered images.
  • Chih's work hasn't been integrated. I also have an idea about the correct multi volume rendering equation.

Downsampler

  • Downsampler has lots of problems and I'd like to completely rewrite the program.
  • OpenGL API will accelerate this process.
  • Thin volume support

Renderer

  • Thin volume support
  • Removing padding

Transfer Function

  • 1D transfer function

Test Set

  • Collect a set of volume so I can always check after major modification of the code

Software Release

  • find an easy workflow minimizing editing
  • script
  • qmake

Long Term Goal
