This image was requested by the
PVG
2003 Conference editors for use as cover image art. It is a close-up
view of OpenRM's direct volume rendering of results from a turbulence
simulation. Turbulence data courtesy of the Center for Computational
Sciences and Engineering at Lawrence Berkeley National Laboratory.

This image shows parallel volume rendering spread over six displays. This
image was created with OpenRM 1.5.0 and Chromium on a cluster of Linux PCs.
You can learn more about how to implement distributed memory parallel
rendering and visualization by perusing the
OpenRM and Chromium pages.

Using RM Scene Graph, different views can be mapped into their own viewport,
all of which appear within a single window. While each camera is positioned
at a different location, there is only one copy of the data in the
scene graph. The isosurface was created by a tool in the RMV library.

One of RM's many primitives are points with normals, or directed
points. This image shows data computed at random positions on the
surface of the sphere. The use of normals and shading creates a
strong impression of surface shape without the use of polygonal data.
One use for this type of primitive is as an alternate represenation
for complex polyhedral models during interactive transformation
(a "level-of-detail" technique).

One of the demo programs in the RMSG distribution can be used
to read and display arbitrary PDB files. This demo programs can
make use of the RM support for background color and depth images
to first create an image of just the balls, then let you rotate
just the sticks. Because the image of the balls also contains
depth pixels, the sticks appear to be drawn "in" the balls,
creating a compelling illusion. Rendering is acclerated in this
mode since the many spheres need not be redrawn on each frame!

What can you do to make a 3D bar chart more interesting? Use a background
image tile! RM supports background images, including depth images. What's
more, you can create vector PostScript directly from the scene graph.
This link is a PostScript file of this
3D scene including the background image tile.
