Hello, This weekend I wrote a triangulation editor, based on the previous code for the graph editor.
You can get the relevant files from: http://www.uam.es/personal_pdi/ciencias/pangulo/etc/te.zip I'm learning mercurial, and the sage packaging conventions, and I need to decide where to place the code before I can produce a patch (suggestions are welcome). Anyway, this is prototype quality (no tests, scarce docstrings, a bunch of NotImplementedErrors...). I placed the python file at sage.graphs, but you can copy and paste into a worksheet if you remove the import statements. The folder triangulation_editor contains the html and js files, and should be decompressed in the folder: $SAGE_ROOT/local/lib/python2.6/site-packages/sagenb-0.7.5.1-py2.6.egg/sagenb/data/ The editor understands only about vertices and triangles, not edges. It shows a grid to which you can snap the vertices, and it can replace the triangles with the Delaunay triangulation for the given set of vertices. It does not produce meshes. I wrote it to complement a sage worksheet I wrote about the FEM. I was quite satisfied as to how the symbolic and numerical abilities of SAGE combined to simplify the definition of the problem and the computation of the solution, but I didn't like having to introduce the triangulation by hand. The workflow would be the following: * use the editor to introduce a first triangulation. * refine the triangulation if needed, without the editor. * setup the problem using symbolic integrals over a general triangle * evaluate the result on the vertices of the triangles * solve the linear system of PDEs * plot it By the way, Ondrej Certik just mentioned he's using Flex to work in a mesh editor: http://groups.google.com/group/sage-devel/browse_thread/thread/c262901cfafd3f45 Regards -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org To unsubscribe from this group, send email to sage-devel+unsubscribegooglegroups.com or reply to this email with the words "REMOVE ME" as the subject.
