OpenRM and the OpenRM/Chromium demo programs are used by the folks at
GraphStream
to show off the interactive
rendering capabilities of their Infiniband clusters. The OpenRM/Chromium
demonstration programs were shown on GraphStream hardware at
IEEE Visualization 2003
and
Supercomputing 2003.

Tim Rightnour is working on a RPG called Genecys --
see www.genecys.org
for more information.
A cool aspect of his architecture is that the universe
and scenery is dynamically generated by the central server, providing
updates to remote clients over the network.

Paul Beardsley and Emmanuelle Bourrat at Mitsubishi Electric
Research Laboratories have created an extremely cool application
that uses imaging technology to automatically discriminate between
ambulatory and wheelchair-bound persons for the purposes of providing
aid to the handicapped, as in automatically calling an elevator without
the need to push a button. Their system uses a number of different
technologies. OpenRM provides the rendering capabilities for the
3D geometry used to give visual feedback during simulation and
system tuning. Their
project page describes the application in more detail.
The application is built from their
Diamond3D Computer Vision Library.
Also, you can check
out one of their MPEGs.

RM Scene Graph was used as the visualization and display engine for a
molecular dynamics simulation conducted by R. Sutton of the
UC Berkeley Geophysics Department.
This link
contains a 100-frame MPEG movie (583896 bytes) showing the interaction of
the water molecules (blues and greens) with cesium (reds).
We were surprised by the effectiveness of multiple views as a visualization
technique in the movies. From a scene graph point of view, there is only one
copy of the molecular data in the system, but two cameras and viewports are
used to achieve the multiple views. With RM's shared data model, the app
can write directly into an area of memory shared by RM and the app in order
to update the molecular positions during each simulation step.

In May 2004, Accusoft
has released VisiQuest™, which was formerly
the Khoros Pro product line from Khoral, Inc.
On-screen images are nice, but scientists and engineers need to
be able to print high-resolution images of their data. One of
the proprietary algorithms of RM Scene Graph supports the creation
of true vector PostScript from mixed 2D/3D scenes. Click
here to download the PostScript file
generated by RM Scene Graph™ for the scene shown here. Note that
there is no direct mapping between many of the features of OpenGL
and PostScript. In particular, PostScript is a 2D-only language, while
OpenGL supports 2D/3D/4D vertex data. Also, OpenGL supports "smooth"
or Gouroud shading, while PostScript supports only flat shading.

VRCO used OpenRM in
an early version of their VRscape product.
