John E. Stone, M.S.
John E. Stone, M.S. is
Senior Research Programmer at the
Theoretical and Computational
Biophysics Group at the
Beckman Institute for Advanced Science and
Technology at the University of Illinois.
He is also cofounder of the
University of Missouri-Rolla
Solar Car Team.
John authored
Random Numbers, Efficiency, and Other Things,
Real-Time GPU Spheres, and
The Ups and Downs of Multithreaded Ray Tracing and
Optimization,
and
coauthored
A System for Interactive Molecular Dynamics Simulation and
Accelerating Software-based MPEG Encoding Using the VIS Instruction
Set.
John is
the lead developer of
VMD, a high performance molecular
visualization tool used by biophysicists and structural biologists all
over the world.
VMD is designed for the visualization and analysis of biological
systems such as proteins, nucleic acids, lipid bilayer assemblies, etc.
It may be used to view more general molecules, as VMD can read standard
Protein Data Bank (PDB) files and display the contained structure. VMD
provides a wide variety of methods for rendering and coloring a
molecule: simple points and lines, CPK spheres and cylinders, licorice
bonds, backbone tubes and ribbons, cartoon drawings, and others. VMD
can be used to animate and analyze the trajectory of a molecular
dynamics (MD) simulation. In particular, VMD can act as a graphical
front end for an external MD program by displaying and animating a
molecule undergoing simulation on a remote computer.
He is also working on a
Tachyon Parallel / Multiprocessor
Ray Tracing System.
He’s been developing a parallel ray tracing library named Tachyon, for
use on distributed memory parallel computers, shared memory computers,
and clusters of workstations. Tachyon supports MPI for distributed
memory parallel computers, threads for shared memory machines, and can
support both simultaneously for clusters of shared memory machines.
Tachyon has been selected for inclusion in the SPEC MPI2007 benchmark
suite. Tachyon supports the typical ray tracer features, most of the
common geometric primitives, shading and texturing modes, etc. It also
supports less common features such as HDR image output, ambient
occlusion lighting, and support for various triangle mesh and
volumetric texture formats beneficial for molecular visualization (e.g.
rendering VMD scenes).
John earned his Bachelor of Science in Computer Science and his
Master of Science at the University of Missouri-Rolla.
