SketchPatch implements most of Processing reasonably well, but some parts of the language are not supported yet. Here is a summary of the parts that don't work yet, or work differently:

- Text and fonts
- Loading / showing images files
- 3d (neither P3D nor opengl)
- Can't instantiate objects outside of a function, i.e. where global variables are usually initiated. Moving the instantiation within the setup method works just fine.
- Filling of curves/polygons/shapes can be different from Processing: (sketchPatch's fill rule is even-odd, while processing is nonzero).
- Conversions between int and float types (both automatic or explicit casting) can lead to different results.

Hi Subpixel,

Indeed, we are working on it right now, and it's looking pretty good. It should be in place in a couple of weeks.

Hello,

just to announce that sketchPatch now reports most types of errors - no more blank stares!
