Getting Back in the Groove

Missed my weekly Sunday post this week.  I had a party on Sunday night for my sister Joiwyn who turned 16.


I am enjoying my rapid prototyping class.  I just finished a lab report about a part I made to test printing threaded holes.  Next we get to test a 3D scanner...  Later we will be making our own 3D modeling software using SAGE and ISM, Implicit Solid Modeling.  SAGE is a free, open source, computer algebra program.  ISM is where you define a shape with a formula, f(x,y)=x^2 + y^2 - 1 for a disc.  This then is used to determine what is inside, on, and outside the object.

I have also been playing with OpenSCAD which is a open source cad engine that lets you model with a script that defines the object and then will render it. Very cool...
