Translate VRML / WRL files to OpenSCAD.
Designed specifically for importing KiCAD PCB designs as references while designing enclosures and mounting in OpenSCAD.
This probably doesn't support 100% of the VRML spec. I've only written it to parse the features in the VRML files I've generated from KiCAD. If it doesn't support your use case, you are welcome to open an issue or PR!
$ cargo run --release <my_pcb.wrl >my_pcb.scad
Write the VRML file to stdin, and an OpenSCAD script will be written to the output, which you probably want to redirect to a file.
You can open the generated file directly in OpenSCAD to view it. It can also
be used in other OpenSCAD scripts: import it with the use
statement, then instantiate the module corresponding to the top-level DEF
,
which is the last module defined in the generated OpenSCAD file. (If it's
from KiCAD, it's probably TXFM_1
.) For example:
use <my_pcb.scad>
// ...
TXFM_1();
The main problem right now is performance, both parsing of VRML and loading in OpenSCAD.
I am currently experimenting with ways to optimize the 3D model before translating, to hopefully improve OpenSCAD loading times.
There is also plenty of room to make the VRML parser more efficient (e.g. reducing copies / heap allocations), but it will probably require a complete rewrite of the parsing functions.
