NXPlot3d version 3.2 - Dec 6, 1994 Copyright 1992-4 Steve Ludtke http://ion.rice.edu/nsci/plotting/nxplot3d.html ftp://ion.rice.edu/pub/next/plotting/NXplot3d.3.2.FAT.tar.gz ftp://ion.rice.edu/pub/next/plotting/NXplot3d.3.2.src.tar.gz NXPlot3d is a 3d graphing/plotting tool designed both for interactive exploration of 3d data as well as production of publication quality plots. Features include: - High speed interactive rotation and zooming. - Plot equations, mesh data, scatter data and/or DEM files - Display multiple sets simultaneously - Several display modes, including surface/mesh, data points, histogram and spherical surface - Flexible surface mapping options including density and contour overlays - Simple one-step animation generation - Full source available A new set of demos can be browsed at: http://ion.rice.edu/nsci/plotting/nxplot3d.html -------- The primary addition in this version is the ability to view USGS DEM files. These files contain detailed altitude information with coverage of the entire US. An enclosed program (demproc) must be used to pre-process DEM files before they can be used with NXPlot3d. PLEASE read the on line docs before you try to do this. There are a number of tricks involved. Here are all of the changes since v3.1: - DEMs (Digital Elevation Maps) can now be viewed (after processing with demproc, also in this archive). Please read the docs before trying to use this feature. You can get DEM's for any part of the country from the USGS. You can download DEMs with 200 foot horizontal resolution from http://sun1.cr.usgs.gov/eros-home.html. -Gradient surface mapping is now supported. Rather than coloring the surface based on the z value at each position, the surface will be colored so steep slopes are considered high and flat areas are considered low, ie - sqrt((dz/dx)^2+(dz/dy)^2) - Surface mapping based on another data set is also now supported (for data set 0 only). This feature still needs a bit of work... - Adjustable transparency (alpha) for data sets is now supported in photorealistic plots. Adjusting alpha will have no effect on the interactive display. ----------- As usual, source is in a separate file. Demos are available only interactively via the web. The most recent version of NXPlot3d is always available at: http://ion.rice.edu/nsci/plotting/plotting.html and via anonymous ftp at ion.rice.edu in /pub/next/plotting As always, I welcome comments/compliments/suggestions.
