Questions about your Rendering Software on SG Iris Workstations
Oops. Forgot to CC this to software. Here's a copy: [ To: wallraff at acds.physik.rwth-aachen.de ] Andreas, We have an interactive display program called "geomview" for IRIS workstations that displays a variety of geometry formats, and a Mathematica package that will convert Mathematica graphics objects into one of these formats. Geomview is interactive --- it lets you move things around with the mouse in real-time. In theory it can handle as many polygons as you want to give it, but of course redraw time is proportional to the number of things being drawn. The maximum number you can have and still get reasonable interaction time depends on the hardware and on the type of data format. The most efficient data type is our "mesh" type; we have heard from people who have successfully displayed meshes with around 300,000 grid points (on a VGX, I believe). All our software is available via anonymous ftp on the internet from host geom.umn.edu. Geomview is in the directory "pub/geomview". You can either get the source-code in the file geomview.tar.Z and compile it yourself, or you can get a precompiled version in the file geomview-bin.tar.Z. Both versions include documentation and example data files. The package that converts Mathematica graphics objects to geomview format is distributed separately, in the file mathoogl.tar.Z. NOTE: the Mathematica conversion package creates "OFF" files, which is one of our geometry formats. For large data sets the mesh type is more efficient. If your data can be represented as a mesh, you may be better off generating a mesh file yourself. (The data file formats are documented in the file man/cat/oogl.5 in the geomview distribution.)
