Raw volume data size 256x64x256 doghead.x - AVS format image of my pet dog at my birthday party. Raw image size is 470x532. The AVS image format is used because it is very simple: first 4 bytes: width of image second 4 bytes: height of image remaining bytes: argbargb... Note that the AVS image format is a non-compressed format. The only image format converter I know of is at SDSC in ftp.sdsc.edu:pub/sdsc/graphics/imtools, and is called "imconv." Pre-built binaries are available for most platforms, except Windows (sorry). A JPEG version of the image is included for your edification (in fact, imconv was used to convert from JPEG to AVS). The Illinois Prairie panorama picture used in tfly.c is Copyright Joseph E. Filer, University of Illinois. He has some great work linked online from http://www.pbase.com/image/20208136. The image is used without permission. The star field is a mosaic of the Cassiopeia constellation, and was snagged from Axel Mellinger's website (located here http://canopus.physik.uni-potsdam.de/~axm/images.html ) and is Copyright Axel Mellinger.
