Paraboloid project is a Scilab script. It produces drawings of “sectors” of a concave surface. If you use this script, you will be able to fabricate concave mirror of any size from (reflective) stainless steel sheets. One can use this to make a concave mirror solar cooker or a parabolic antenna.

  • The project zip file contains the program script. This must be run in the Scilab environment. Scilab is free. Download Scilab.
  • The project zip file contains the e-book (pdf) explaining how to use the script to fabricate the concave surface.Download project paraboloid using Scilab .
  • The project also can be run using another free software, GNU Octave. Here is the Octave script.
