[sage-support] Re: 3D animation
Thanks, but I forgot to say my colleague has actually looked into Jmol and his conclusion is that the language is a bit too "Chemistry oriented" for him. That's why he goes back to use Mathematica. I surely hope SAGE can tap into the power of Jmol in a not too distant future. Meanwhile we will give the Tachyon method a try.

I just wonder if > there is any update (easier way) to do this. Jmol (our 3d graphic viewer) has some very nice animation capabilities. We haven't tapped those in Sage yet, though. There are lots of demos up online. A quick Google search yields these, for example: http://jmol.sourceforge.net/demo/animation/ http://www3.interscience.wiley.com:8100/legacy/college/boyer/0471661791/structure/jmol_intro/jmol.htm http://www.umass.edu/molvis/martz/lectures/labmolgen/mj2.htm http://www.chem.ucalgary.ca/courses/351/Carey5th/Ch03/ch3-06.html Basically, jmol has a scripting language that lets you animate things in the image.

[sage-support] 3D animation
A colleague of mine would like to produce some 3D animation (an illustration involving cones and spheres). He looked into SAGE and said it will be difficult compare to Mathematica and so he decided to use the latter. By reading this group, I understand one can render the images via tachyon then produce the animation by imagemagick. I just wonder if there is any update (easier way) to do this. Also it looks like some of the older correspondence in this group is not available (can see the title) but not the content, can someone tell me why?

I think this error is very annoying, as I am getting it on basically all computers where I tried it. When I get some time, I'll try to figure out how to patch jsmath not to show this message at all.

[sage-support] ideals of points
Hi, I have the following homogeneous Singular ideal defining a finite set of points in projective space. I would like to get numerical approximations for these points. sage: S.ring() // characteristic : 0 // number of vars : 4 //block 1 : ordering dp // : namesx_3 x_2 x_1 x_0 //block 2 : ordering C sage: S.ideal() x_1^3-x_3*x_2*x_0, x_3*x_2*x_1-x_0^3, x_2^3-x_3*x_1*x_0, x_3^3-x_2*x_1*x_0, x_2^2*x_1^2-x_3^2*x_0^2, x_3^2*x_1^2-x_2^2*x_0^2, x_3^2*x_2^2-x_1^2*x_0^2 sage: type(S.ideal()) One way to go might be to map to a new ring, setting x_0 = 1, then use the nice Singular algorithm for finding the solutions: http://www.singular.uni-kl.de/Manual/3-0-4/sing_582.htm I couldn't figure out how to get the Singular "map" function to work with Sage, so I just converted equations using string commands (saved in "y" in the following code) then tried: sage: R = singular.ring(0,'(x_3,x_2,x_1)','lp') sage: J = singular.ideal(y) sage: J -x_3*x_2+x_1^3, x_3*x_2*x_1-1, -x_3*x_1+x_2^3, x_3^3-x_2*x_1, -x_3^2+x_2^2*x_1^2, x_3^2*x_1^2-x_2^2, x_3^2*x_2^2-x_1^2 sage: K = J.groebner() sage: M = K.solve(10,1) I'm not sure where to go from there. Of course, I might be taking the wrong approach altogether. Any advice would be appreciated.

[sage-support] Re: sws vs pdf
Just a last followup (ignoring the efficiency issues): Would it be possible to add a "Download Latest Revision Only" option under "File..." or "Download Text File Only" or something like that (which would still be accepted as an upload, of course)? Even when one clicks "Text", it still prints as the actual output view, which isn't the same. Presumably this option would simply save worksheet.txt to the local disk. That would be MUCH better for most ordinary purposes that don't need the umpteen revisions history when sharing, especially since it's a bit difficult to share from one's personal computer to the rest of the world when one's computer is offline :) If this seems amenable, I will open a ticket for it. - kcrisman --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Bump. Again, I'd be happy to open a ticket but first would like confirmation that this is, in fact, a bug, and not desired functionality. - kcrisman On Feb 17, 2:56 pm, kcrisman wrote: > Dear Support, > > Viewing block matrices "nicely" seems to be difficult in Sage. > > sage: A=matrix([[1]]) > sage: B=matrix([[2]]) > sage: C=matrix([[3]]) > sage: D=matrix([[4]]) > sage: BM=block_matrix([A,B,C,D]) > sage: BM > > [1|2] > [-+-] > [3|4] > > Okay, this is fine but a little clunky.
