What: Static and dynamic Analysis for 2D-Frame (Version 2007) Where: http://sicheng6699.googlepages.com/ Description: With it you can calculate a Frame's forces (N,Q,M), Displacement and the eigenfrequency(eigenvalue) and the natural mode. Updated: 25/08/2007 Contact: sicheng6699(AT)gmail.com

Description:
I have used Tcl/tk for the GUI, Fortran for the calculation, Lapack-library for the numeric algorithmus(linear equations,Eigenvalue).
I will keep working on it.
I will be very glad to discuss it here.

Question 1 : IF I want to do someting with 3D-Framework, should I use 3dcanvas ? oder hoco an homogeneous coordinates package? Someting like:
RS: You might evaluate those (I haven't tried them much), but for wireframes it's very easy to define a function that transforms {x y z} coordinates in 3D space to {x' y'}.. the trickiest problem in my experience was detection and covering of hidden surfaces.
GS 2007-09-03 You sould give a try to 3dcanvas (http://3dcanvas.tcl.tk/ ). This version written by DRH acts like a 2D canvas. See the man page at [L1 ]. But you have to compile the package for the target platform and its depens on OpenGL.
