Web-based parametric modeler: first steps

I’ve recently started working on a web-based parametric modeler for making 3d-printable panels full of greebles/nurnies using javascript and Three.JS. The general idea is to have a base shape and allow the user to draw rectangular sections that then get filled in with additional details.

Currently, the system supports beveled extrusions and arrays of buttons, but more feature types are on the way. To see it for yourself, head here:

PLARL: Roguelike Celebration talk

The Roguelike Celebration is an annual mini-conference on roguelike games and procedural content, currently in its fourth year. I’ve gone the past three years and its always wonderful- highly recommended.

This year, I was lucky enough to get to present a short talk on my 3d-printable roguelike, “PLARL” (short of the poly-latcic acid roguelike). The talk (along with all the other, even better talks given by other contributors), is up on youtube and viewable here:

Also, if you’d like to see the slides from the talk, they’re available here:

Also also, I have all of the code for both the OpenSCAD model generation and the JS-based maze generation available on github here:

PLARL: the 3d printed roguelike (proof of concept)

This was a project to generate a 3d printable dungeon using OpenSCAD. To play the game, the player uses a screwdriver or similar to break away parts of the printed model, revealing additional information.

The result has multiple layers stacked on top of each other, with the bottom layer (red) consisting of the maze pattern, the middle layer (green) supporting iconography for things like monsters, and the top layer (blue) being the door. Both the blue and green layers break away.

To see a playthrough of an example level, check out this video:

More fun with OpenSCAD

So I’ve been having a great time with OpenSCAD of late, and made a couple of small models:

  1. a parametric Lincoln Log-style building piece (with options for diameter, length, and number of slots)
  2. a die-like cube for tracking damage in World of Darkness pen-and-paper RPGs

I love OpenSCAD, and I also love thingiverse. To check out the models and download them for yourself, head over to my thinigiverse profile.

Binary rings (via OpenSCAD)

So a while ago, I started in on a project to create a tool for generating wearable ring models with text encoded in binary based on the ASCII values of each character. I put the project aside a while back, but recently I discovered OpenSCAD, a fantastic tool for programmatically defining 3d models.

OpenSCAD totally rocks, but is a little strange in that variables aren’t, strictly speaking variable, since you can’t change their value. As a result, instead of writing openSCAD directly, I created a Python script that takes a string as a command line argument and generates the OpenSCAD code to make a ring with that phrase around it. The above image encodes ‘OpenSCAD rocks my world’.

The next steps are to make the script take a ring size and thickness, and then I’ll likely be setting up shop on Shapeways to sell these.
