ivr − description of Intermediate Volume Rendering format |
The Intermediate Volume Rendering (IVR) format is
a volume data format intended to allow very fast
transfer-function previewing of a dataset from a
predetermined viewpoint. This man page describes version 0 of the format. |
IVR is a binary file format, and rather
simplistic. All data are either 32-bit integers or 32 bit
floats, and are stored in little-endian format. A sample ray is a variable-length record
consisting of an integer N representing the number of
samples in the ray, followed by exactly N samples.
The samples are stored in back-to-front order |
In this example, we show an initial segment of an
ivr file. For purposes of text formatting, we use
angle brackets to denote the binary representation of a
value. |
