[sage-support] saving a java3d figure

2012-07-30 Thread entropy
Hi all! How does one save an image created using java3d. Eg., T=Torus(1, .5, color='red',opacity=0.3) T.show(aspect_ratio=1,frame=False,viewer='java3d') displays a beautiful, interactive torus. But how can I save it? thanks, Jesse -- To post to this group, send email to sage-support@googlegr

Nathann, Many thanks! You're awesome! I looked at the patch, it looks tiny. :) I'll try to test it asap. Having some patch application issues. :-| Just in case you're familiar with this, I'll throw it out there. But this is probably a job for google: cd "/Applications/sage/devel/sage" && hg impor

Hi Nathann, Thank you for the timely updates! I agree with you about the calls to random. I can move those out of the timing portion. I suspected that the passage to the backend was probably responsible for the slow speed of the add/remove edge/vertices calls. The cost of method calls is overhead I

Hi Nathan, Thanks for looking into this. I believe that I stayed within Sage's library when I wrote my test code. The general outline and some classes were originally written by a collaborator (I don't want to take credit, but I'll take responsibility where there are errors!) I couldn't find a way

Hi all, I'm benchmarking some graph libraries. I was excited to see that Sage's graph library has a backend implemented in Cython. Unfortunately, it seems to be orders of magnitude slower than a pure NetworkX implementation. Here a code summary: import networkx # read in test adjacency matrix us

Hi all, I'm attempting to build Sage on a SUSE Enterprise 10 (SLES 10) cluster. I have run ./configure as follows: ./configure SAGE_FORTRAN_LIB=/usr/lib/libgfortran.so.1 SAGE_FORTRAN=/ usr/bin/gfortran CXX=g++ CC=gcc The error is related to the install of python2.6. Why did configure choose /loc
