MIT IAP RhinoScript workshop - Danzer Variations

While looking for RhinoScript resources for the Digital Architecture workshop at AHO I found a recent posting of the final projects from a RhinoScript workshop at MIT IAP. It features some very nice-looking work, including the Danzer tile forms shown above. It also provides the source code for most of the experiments, well worth checking out.

The resource page for a previous MIT workshop is still up, it has more scripts and some useful links: Computational Design Solutions Part 1.

I am teaching a 3-day workshop in Digital Architecture at the Oslo School of Architecture & Design (AHO) this week, as part of a course by Søren Sørensen. The workshop will give an introduction to Processing, with a focus on synthesis of spatial form. If time permits we’ll also look briefly at Rhinoscript.

Be sure to look at the page I have prepared with links related to computational architecture. Code will be uploaded to:

• Basic Processing syntax
• Simple animation
• Control structures: If / else, loops, keyPressed(), mousePressed()
• Transformations: translate(), scale(), rotate()
• Complex drawing: beginShape(), endShape()
• Data structures: Arrays, classes
• Polygon mesh generation
• Output: PDF, STL, DXF

• RhinoScript
• p5Sunflow, a radiosity rendering library for Processing

Rhinoscript sketch, extruding a revolution surface along random curves. Good cheesy fun.

I had a chance to see a bit more of the impressive tool Rhino 4 during the Generator.x 2.0 workshop, and so I thought I’d have a go at making a simple sketch in Rhinoscript. As it turns out, the fact that Rhinoscript is based on VBScript makes coding feel horrible at first. Seriously, who would want to use syntax like that? It might be easy for beginners to pick up, but it quickly gets painful once you’re dealing with complex API calls and 100+ lines of code.

Nevertheless, frustration soon gives way to amazement at the built-in Rhino library and its vast array of heavy-duty functions for creating and manipulating curves, meshes and NURBS surfaces. In comparison, mesh generation in Processing is enough to give anyone a headache, and I seriously doubt anyone would even attempt to implement NURBS. Even Boolean mesh operations is a staggering task, with no good Java libraries readily available.

While Rhinoscript is firmly a non-realtime tool, its power for pure geometry is amazing. I would definitely use Rhino as a creative tool for digital fabrication projects, where animation is not the goal. There are some excellent RhinoScript resources online, for starters look at RhinoScript 101 and David Rutten’s tutorial. I would also definitely recommend using the Monkey Script editor instead of the built-in editor, it’s more powerful and has a very useful documentation feature.

The script below gives a basic idea of the Rhino syntax, and while it is a basic sketch suffering from 3D clichées, it shows the power and versatility of Rhinoscript. I just wish it wasn’t Visual Basic.
