ginzu for NeXT geomview
I am teaching a calculus course this semester using Mathematica on NextStep machines. We will do some things with calculus with several variables and I will use geomview for some of the topics. There are a lot things that I can do now with geomview as is, but two modules, not yet implemented for Next would be helpful to have: 1) Transformer 2) Ginzu The most useful of these two would be Ginzu, (I could make a crude Transformer myself) Is it possible to get versions of these modules soon? I will be getting to the material that would need Ginzu in about 10 days. I know that's pretty short notice. But maybe it is possible to get a command version of ginsu. It might go something like this: In the command panel window one would type: (| path/cutit a b c d) where a, b, c, and d are floats. This would take the targetgeom (if not the world) and cut it into two pieces by the plane ax+by+cz=d. (so in the above "cutit is a shell script which might run a command line C version of ginzu. Or something like that.) ----------------- Notes: 1) most of the cutting we need to do in the class are cuts parallel to a coordinate plane. 2) The following modification of Ginzu would be useful (with whatever kind of interface). I will describe it in terms of the hypothetical "cutit" above. The idea is to cut the targetgeom into uniform "slabs" between two given planes. (| path/cutit a b c d D n) where a, b, c, d, and D are floats and n is an integer, 2<=n. would slice the target geom with n planes it would slice at ax+by+cz=d it would slice result at ax+by+cz=D and then also (if 2<n) slice at ax+by+cz=d +(D-d)/(n-1) then slice at slice at ax+by+cz=d +2*(D-d)/(n-1) etc. So (| path/cutit 0 0 1 -3 3 7) would cut the target geom by the 7 planes z=-3, z=-2, z=-1, z=0, z=1, z=2, z=3. &&&&&&&& If you can't get to this, I understand. I should have thought of this earlier. Just let me know and I'll see what I can hack out myself. Dennis
