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

writing vvVirTexRendMngr, vvVirTexRend class, rewriting BrickManager

Done

• add new interface for multi volume management

July/01/2008 (Tue)

writing vvVirTexRendMngr and vvVirTexRend class

June/30/2008 (Mon)

working on multi-volume support. need to change most part of brickmanager and renderer.

Done

• multi-volume support
  • new configuration file format for multi volumes - distinguish from multi-time steps

Yes, it doesn't go away..

June/25/2008 (Wed)

still horrible,

Done

• write a script to automatically generate shader programs

June/24/2008 (Tue)

still sick

June/23/2008 (Mon)

Done

• cleaned up code
  • get rid of BrickInfo::actualCoord, coord is enough
  • clean up brickReader, mvfData, tiffData in MipMapVideoLib
  • clean up downSampler2D, downSampler3D

June/22/2008 (Sun)

was sick...

June/21/2008 (Sat)

Done

• fixed a bug, boundary blurring when texture enabled
  • didn't explicitly disabled each of multi-textures separately
• Modify downsampler and reader
  • with padding
  • tested on 2D and 3D

June/20/2008 (Fri)

Done

• factor out setViewPortCorners calculation from brickinfo to vvVirTexRend
• trying to add paddings but it doesn't work!

June/19/2008 (Thur)

Done

• modify MipMapVideo.pro to include my own virvo library => be sure to modify back after svn committing virvo library
• User Interface (in covise)
  • select/(de)activate channel - add menu
  • adjust HSV value
• add a namespace, MipMapVideoLib, to all classes

June/18/2008 (Wed)

Done

• change memory pool mechanism with Pixel Buffer Objects
  • reimplemented
• fixed bugs
  • change BrickInfo::getMemoryUsage() to BrickManager::getMemoryUsagePerBrick()
  • change constant in CubeInfo::setFiner()
• svn commit

June/17/2008 (Tue)

Done

• Multi-channel user interface in glui
  • used a linear transfer function
  • adjust hue in HSV for each channel using a scrollbar
  • de/activate channel using checkboxs
  • tested on 2D and 3D
  • svn commit

June/16/2008 (Mon)

almost nothing :(

June/15/2008 (Sun)

Done

nothing.. :(

June/14/2008 (Sat)

Done

• debug shader program for 3D
• svn commit

June/13/2008 (Fri)

Done

• change multichannel (RGB) read to three single channel reads
  • integrate with shader programs
  • use different file format
  • use additional configuration file parsing to read shader program information
  • clean up old code
  • tested on 2D

June/12/2008 (Thur)

Done

• implement texture pools
  • use glTexImage2D for initialization and glTexSubImage2D for update
  • pool management, issue/reclaim a texture name
  • tested on 2D and 3D testsets
• remove GLUI library from meshTester directory and use a separate copy of GLUI
• found and fixed a bug, a value was set to INT type, which caused the value to be always zero..
• update SVN repository with the current version
