Cura WASM Version 2

FAQ's

What

This is a thread to get some ideas going for Cura WASM Version 2.

When

Version 2 is targeting release in late summer (2021).

Why

Because the Cura WASM API could be better and it could expand beyond the JS/TS ecosystem.

Overarching Goals

1: Clean up the API

This could be accomplished by allowing API consumers to mix overrides and CLI arguments. This could also be accomplished by splitting Cura WASM into a core repository (Which would include a virtual filesystem, minimal output processing, and multithreading) and a higher-level API repository (Which would take care of definitions, common object transformations, and other features people new to Cura Engine would appreciate).

2: Add support for common transformations

This would add support for easily transforming (Translation, rotation, and scaling) objects. Currently, translation and scaling should be easy to do but rotations require computing a rotation matrix and feeding that to Cura Engine. If the matrix computation were to be included with Cura WASM, this would greatly reduce the amount of code API consumers would need to perform rotations on objects (Including for Cloud CNC itself).

3. Convert Cura WASM to a WAPM package

This would allow people to use Cura WASM outside of the JS/TS ecosystem since the Wasmer runtime has a bunch of language bindings. Internally, Cura WASM would actually use the JS Wasmer integration to interface with Cura Engine. This would have no impact on the exported Cura WASM API.

4. Improve file support

Although this is more related to unified-3d-loader, it would be nice to have better support for various 3D formats (Chiefly .3mf, .amf, .ply, and maybe .obj). This would NOT include adding additional formats but simply improving the existing ones. If you'd like to see more formats supported, feel free to open a PR.

I would say that the setting files could be left out of the WASM binary so long as it would be possible to push slicing configurations in to the virtual file system.

[Wakeful-Cloud]

Would you want definitions to be supplied by Cura WASM or would you want to bring your own definitions (Basically writing JSON files to the virtual filesystem)?

[mmiscool]

I was thinking that being able to write my own JSON files to the file system for it to use.
