Mipmap Generator 3D Manual

Generate mipmaps for 3D volumes.

The 3D generator is basically the same with the 2D one, except there's one more dimension for the z-value. In the 3D manual we'll just mention those parts different from 2D generator.

Text Files

1. Output text file and the output batch file (outputBatchFilename)

In the 3D generator, the output text file and the output batch file are in the same format. The output text file first starts with a line specify the dimension of the input image/volume (2D or 3D) and the number of volumes listed in the file. Then for each volume, it listed the related information such as maxLevel and brickSize, and file path for all its output mipmaps.

Sample file (a line starts with ‘#’ is a comment line):

   # dimension, # volumes
   3 2

   # Volume example1.xvf
   # Volume definition (volume number, brick size, maximum mipmap level, # channel
   0 128 2 3
   # mipmap level 0 definition (mipmap level, file name, size in X, size in Y, size in Z
   0 /home/kushu/mipmapGen3D/example1.0.xvf 512 512 42
   1 /home/kushu/mipmapGen3D/example1.1.xvf 256 256 21
   2 /home/kushu/mipmapGen3D/example1.2.xvf 128 128 10

   # Volume example2.xvf
   # Volume definition (volume number, brick size, maximum mipmap level, # channel
   0 128 2 3
   # mipmap level 0 definition (mipmap level, file name, size in X, size in Y, size in Z
   0 /home/kushu/mipmapGen3D/example2.0.xvf 512 512 42
