+<b>Show virus gray levels on spherical surface</b><br>
+Tim Baker<br>
+January 23, 2009<br>
+Want to be able to interactively adjust sphere radius while displaying virus
+map gray levels on sphere.  Chimera can do this now by combining the Icosahedron
+tool and surface color tool but there are two problems: 1) too slow when showing full
+resolution data, and 2) many steps required to set up this mode.  The first problem
+is partially alleviated by the per-pixel coloring option of the surface color tool
+which allows full resolution volume data display on a coarse triangulated surface.
+But that requires that the full volume data fit in an OpenGL 3d texture which limits
+this technique to small maps.  Would be useful to have a special purpose tool to ease
+the setup of this useful viewing mode.  Baker lab uses RobEM program developed at Purdue
+for this but it can only handle limited map sizes.
