I spent the last few years making a powerful 2D art and animation tool for the iPad in my spare time and it’s available now! All feedback is greatly appreciated! ❤️

@pcwalton Also just thanks for all of your insights so far!

@pcwalton And did you ever happen to be able to do side-by-side benchmarking of Pathfinder against Slug?

@pcwalton Paper.js uses Bézier clipping as far as I know and I don't think they even try to handle the inevitable precision issues that come with that approach. The clipping will regularly lead to one curve being very small while the other is still long, causing significant FLTp errors.

@pcwalton It's easier to implement for sure but the stencil-based approach unfortunately kills the rendering performance when there are a lot of shapes.

@pcwalton If there are multiple identical curves (i.e. with perfect overlap) in the shape, those need special treatment as well, since no amount of splitting will stop their bounding triangles from overlapping.

@FreyaHolmer GDPR generally requires opt-in consent for everything (you can't even have a checkbox for an optional newsletter pre-checked). Patreon probably also had you sign a data processing agreement with them that defines how you can use a supporter's e-mail address.

@LapisLutea No. I have the videos that I originally saw of similar simulators that inspired me to make mine linked in the description of this video: Maybe one of them is the one you're thinking of?

@SebAaltonen @tontsa

@SebAaltonen @tontsa There's currently a bug in the latest Xcode version (14.3) that causes apps to crash at startup on iOS 13. If that's the same issue here, you should try building with the previous Xcode version.

@SebAaltonen The error also says "unrecognized selector", which means that the "setType" function doesn't exist.

@SebAaltonen The feature set table says that "placement heap" is supported in Apple2 (A8) and above: So the effective min spec seems to be a combination of A8 and iOS 13
