The dotGo go3dprint demo

These are the files used in "the dilators talk" that took place at dotGo 2019, in Paris.

The full version

For the live demo (the code on this repo) a simpler version was used. The main difference is that the full version is "cloud-native."

(The differences and the conversion process are explained in detail in the article Needlessly Distributed Phallic Object Generator.)

While the simple version compiles into a single binary and runs locally on my OS, the full version uses Garden and has a more 2019 look to it:

• Functionality is split into loosely coupled microservices
• Running as lightweight containers
• That communicate via API calls.

And the configured workflow:

• Re-builds and re-deploys on every code change
• Can use hot reload, so containers can be update without restarting
• Uses the same tooling for all environments—local, CI, remote.

It also has a really cool frontend:

The full version can be found here.

Usage

This demo is made to run on Linux (it might work elsewhere, but I haven't tested it).

Besides Go, it requires entr for file monitoring, and inkscape to convert SVG files to PNG for visualization. (Inkscape is not necessary in the full version.)

You can install both with sudo apt install entr inkscape on Ubuntu.

To then run it with live reload capabilities, do:

$ ls *.go | entr -r ./reload.sh

• Most of the demo took place in mesh.go.
• Just find the big "FUN" banner and start un-commenting and saving.
• The results will output to mesh.png and vector.png.
• You can switch renderers between fauxgl and path tracer by commenting/uncommenting the relevant bits on render.go.
