SuperShapes in OpenScad

thingiverse

Revamping the textual information... In my Design 101 class, I was teased for my unique shapes in a project. To silence the mockery, I developed the SuperShapes using a set of formulas. These super forms can be viewed on Paul Bourke's website along with the math behind them. The challenge lies in adapting these complex formulas into OpenScad to generate 2D models that can be converted into 3D printable .stl files. The supershape.scad file contains two crucial routines: RenderSuperShape2D() and RenderSuperShape(). The former creates a 2D curve of a single supershape, while the latter combines two supershape definitions to create visually appealing models. Additionally, you can use parameters from POVRay files to experiment with different shapes. This code also includes procedural texture mapping for checkerboard patterns, eliminating the need for bitmaps. It's public domain and encourages users to explore various shapes. If you're using OpenScad, try displaying wireframes with a fade effect. As an update, a deadly weapon in hardened steel can be created by rendering 2D shapes with faces using CSG operations. To use this code: 1) Download the .scad files. 2) Open the test_supershape.scad file and play around with routines. 3) If you like a model, generate a .stl file. 4) Print it out. 5) Enjoy your unique creation!
