Isosurface Burr Bowl

Designed by   Simon Scarle

Description

Summary Once again an isosurface, this time to produce something that to me looks very like the traditional wood crafts idea of taking a wooden burr nodule from a tree and making a decorative bowl from it. My wife has described it as being very tactile and pleasing to hold. Print Settings Printer: Eaglemoss Vector3 Rafts: No Supports: No Resolution: 0.2mm Infill: 10% Notes: The model is in the STL file upside down so that it requires no supports. How I Designed This I started with some code I give my students to help them start 3D graphics projects. This helps them create models in Vertex and Index Buffers programmatically. I then grabbed the Marching Cubes function from here, and used it so that I could feed in an equation and get out a Vertex Buffer containing a given iso-surface of that equation, display it and then spits out a basic obj file. After much playing with various equations I got a mostly spherical object with strange tubes running through it, from the equation given below. This was then put into Netfabb, where I sliced it in half and also a sneaky slice on the bottom to allow it stand better. Lastly, a sphere was take away from the object using Boolean operators.

Equation ((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
