Hi DX weenies, I've been lurking on this list for a while and I have found the answers posted here to be very informative, so thanks for that. Till now my own experience with DX has gone pretty smoothly.
Now I am looking for a capability which doesn't seem to be mentioned in the documentation, or the archives. Apologies if I have missed something obvious here. What I want to do is perform surface integration on a 2-d surface in 3-space. I have a scalar component on a field in 3-space, with regular connections. Right now, I am marking positions, calculating the distance from the origin, taking that through isosurface, and marking the scalar component again. This gives me a new field. The positions are irregular and are in the form of a sphere. The scalar field is interpolated onto this sphere. It looks fine when rendered. Now I want to calculate the integral of the scalar over the surface. It seems that in terms of the computational work I'm almost there, but I can't figure out how to proceed. Any help appreciated. Thanks, Greg Ball -- Astronomy Dept. Harvard University
