Repin" Subject: FREE PROGRAM: 3D DEM/fault/earthquake/focal mechanism visualization X-To: SEISMD-L@bingvmb.cc.binghamton.edu To: Multiple recipients of list SEISMD-L Content-Length: 2903 X-Lines: 60 Status: RO Dear netters, For those of you who need/would like to do 3D interactive visualization of their DEM/fault plane/earthquake location/focal mechanism data, but don't have $$s to buy fancy commercial software, here is a simple (well, may be too simple :-) ) FREE solution... I have just finished a second version of a small program that does the described above things. THE PROGRAM IS FREE TO USE. The program displays in 3D: =========================== * GMT Digital Elevation data as a 3D color-coded relief surface; * Almost arbitrary 3D fault surface (you can specify a surface by digitizing elevation contours of the surface or by using triangulation); * Earthquake locations (as dots in 3D with the size proportional to the magnitude); * Earthquake focal mechanism data (moment tensor principal axes or a double couple beach ball) by drawing 3D axes, fault planes, "beach balls" (or all of these together) with the size proportional to the magnitude. Examples of the graphical output and description at: =================================================== http://seismo.geology.indiana.edu/hyplan/drepin/CLASSES/B581 Some features of the developed program: ======================================= * The program does not need any other special software. Current version of the program is supposed to be able to run on any SGI or SUN(Solaris) machine (the code can also be recompiled to run under Windows 3.1x/NT, Linyx, and Mac OS). * Exemplary drivers for reading files in Harvard CMT and SELECTCMT2 formats are provided. ********************************************************************** *** I am welcome to ANY suggestions both about program structure *** *** and functionality and about possible applications for it. *** *** e-mail me at drepin@indiana.edu *** ********************************************************************** The program and exemplary data can be downloaded FOR FREE from: =============================================================== SGI executable: ftp://ftp.geology.indiana.edu/pub/drepin/3DCUBE/SGI.1.03 SUN executable: ftp://ftp.geology.indiana.edu/pub/drepin/3DCUBE/SUN.1.03 See you at my home page :-), D.
