Why a portfolio/showcase ?
I have worked on a lot of projects in the past decade, on a lot of 3D/webgl/CAD/3D printing etc, quite visual (very often web, based) projects, so it recently dawned on me: let's have a nice visual showcase ! I love learning, challenges, finding the right tools for the job, as you can see in the list below.
Jam / usco
A very modular, multi platform Webgl app for collaborative editing & sharing of 3d designs for Ultimaker/Youmagine.com for 3D printing & more

Key points:
- blazingly fast , streaming parsing for various 3d formats (stl, amf, 3mf)
- mobile (UM3 app), Web, and backend (thumbnail generation using Headless webgl rendering)
- bill of materials, shared 3d designs and a LOT more !
Showcase:


OpenJscad/ Jscad
A procedural, code based 3d modeling tool, for the browser, desktop, CLI & more ! Ie: write some code, get a 3d printable design !
A project with a huge scope and possibilities

Click to learn more!
Key points:
Over the past (5+) years I was a core developer/maintainer of OpenJscad
- Upgrade to modern Es-next, development of core features & UI of parametric 2D/3D modeling program (Javascript, Node.js)
- development of core modeling & maths features, UI
- migration from monolithic code to node modules
- setup and addition of a huge amount of unit test
- I did a talk at HannoverJs a few years back that explains the scope and challenges of my work on the project
- I also created Electron based experimental Desktop app
- latest versions also support decentralized design sharing using the dat protocol / beaker browser
Showcase:


- Using the principle of 'dogfooding' (actually use the software you are developing), I often used the software to create robots, pcb housings, gardening tools etc
Variations
Signed distance field modeling
At some point I also experimented with purely GPU based rendering based on signed distance fields as a possible frontend/renderer alternative



Coffeescad
I also worked on a fork in CoffeeScript for a while called ... Coffeescad !
There is an interview I did about it for the German It/tech journal Golem
Simple-scan
A full blown 3d scanning app in the browser , with connected dedicated hardware ! It was done for the KIT in Germany, Karslruhe

Key points:
- polymer.js / web component based
- hardware connection
- pleasant, easy to use user interface
- ported c bindings to enable use of native libraries for camera/hardware access
Showcase:


3d printing
A long standing passion & work of mine is 3d printing, in all its aspects: software, hardware, electronics, processes

Click to learn more!
Key points:
- design & build of multiple 3D printers
- custom firmware development (C/C++/Arduino)
- front end / UI development in Python & Js
- 9 + years of experience both for 3d printing Companies (Ultimaker) & personally
- 3D printing workshop organization for adults & children
Showcase:





Electronics/ Robotics
A lot of my hardware projects also revolve around, or have included electronics/sensors actuators !

Click to learn more!
Key points:
- parametric versions of 3D printable robots
- custom electronics, with home made PCB designs
- lots of experience with using off the shelf components for sensors, actuators, etc (Arduino, Esp8266, Raspberry Pi)
- coding custom firmware (c/c++/Arduino/PlatformIo) for robots, sensor networks (Mqtt...)
- live coding video series mixing Hardware/Firmware & web dev
Showcase:



3d visualization
In my carreer I have also been working on different types of data visualization in WebGL & 2d

Click to learn more!
Key points:
- built specifically for client needs
- performant WebGL (GPU instancing etc)
- lean/ minimalistic implementations
Showcase:


Game engine/ tech exploration
This personal project was a breeding ground to learn/ deepen my understanding about a lot of technologies, and how far you
can push a 'tool-less' web stack (no build steps, using native esmodules only as much as possible)

Click to learn more!
Key points:
- ECS implementations
- experimentation with Webgl & WebGPU
- heightmaps, physics, all in vanilla js
- experimentation with Quick.js / embeded js engines
- electron app with sound, gamepad etc support
- python code for Blender add ons
