Isosurface Burr Bowl

pinshape

I create 3D models by starting with code that helps my students get started on graphics projects. They use it to build models in Vertex and Index Buffers programmatically, which I then modify using the Marching Cubes function from here. This allows me to feed equations into the model and get a Vertex Buffer containing an isosurface of that equation, display it, and output a basic obj file. After trying various equations, I found one that produced a mostly spherical object with strange tubes running through it: ((1.0 / 3.0)*(cos(x*x) * cos(y*y) * cos(z*z)) + (1.0 / PI)*(x*x + y*y + z*z) - sqrt(x*x + y*y + z*z) - (1.0 / 2.0)*(cos(x*y) cos(y*z) cos(z*x))) = 0. I then sliced the model in half and added a small slice on the bottom to make it stand better using Netfabb. Finally, I used Boolean operators to remove a sphere from the object.
