Filtered point-sampling in volumes

gage is a library for measuring quantities at arbitrary locations in a rectangular lattice volumes, by using convolution. It can measure values, and/or take first and second derivatives. Currently, measurements in scalar and 3-vector volumes are supported, but any kind of volume can be probed given a pointer to a struct containing the arrays and functions required to describe and manipulate filtered data of a given type. The kernels used to do the measurements are nearly arbitrary- gage takes pointers to NrrdKernels, which can come from the nrrd library directly, or can be user-defined. gage does the measurements needed for mite, bane, mrender, and the qbert program for generating "VGH" volumes for Simian

This library is very nearly finished, but this documentation is obviously just getting off the ground. For the time being, refer to this text file description.
