[x3d-public] X3D scene from gemc particle beam simulation

[Vincent Marchetti]

At the Feb 10 N Polys shared some links about GEMC, a particle beam simulation program which offers  3d visualization in vrml 2 -- which is readily converted to X3D. This program is in use at Jefferson Labs in Newport News, VA.

Those shared links are (courtesy of D Brutzman's meeting minutes):
	• VRML: https://gemc.jlab.org/gemc/html/index.html

I've been able to do this X3D output for one of the example scenarios offered at the Jefferson Labs site, a 1 GEV proton beam impinging on lower GI track (ouch!) , with the heart, and brain nearby. An eventual goal of this type of simulation would be to evaluate the radiation dosage which 'leaks out' to affect these other organs. Do note that the geometry , and material properties given on this example archive are not research-grade. However, if does allow a demonstration of X3D visualization of the results, which can be seen (rendered in X_ITE) at :
