Texture Mapping A Sphere

This program demonstrates procedural texture mapping in 3d by choosing the colors of the surface of a sphere according to a 3-dimensional coloring function.

Using wxPython/OpenGL to draw a sphere script is a simple wxPython/OpenGL application to draw a sphere.

The Heating and Cooling a Sphere model computes the radial temperature distribution within a sphere as it is heated and cooled by a surrounding fluid. The sphere is broken into shells and the temperature of each shell is computed using a finite difference approximation to the radial heat equation...

The MATLAB file contains a method to find the value of pi. This is just an extension of the general method of finding pi from within a circle. It uses 3D-matrices and some more stuffs, which can be very helpful for educational purposes. Also, do change the values in the file, to see for yourself,...
