Something broke with the optimizer since last Penrose week

6

A bunch of examples, like those in `triangle-mesh-2d`, no longer work. The optimizer gets stuck for most seeds, and can't make any progress. I tried creating a minimal example that...

A common usage pattern for using Penrose would be to, e.g., write programs in the directory for a paper, and run Penrose from that directory. Right now, it seems, we...

**Is your feature request related to a problem? Please describe.** In Penrose, as in other systems for constraint-based drawing (Cinderella, Geogebra, etc.), one runs into trouble when the calculated quantity...

Naming of color-related fields for graphical primitives

2

Currently, there are shapes (such as `Circle`) that have fields named `color`. Three problems here: - `color` is a name conflict with the `color` type (confusing!) - the word `color`...

Support meshes with multiple components, nonmanifold meshes

1

Should be an easy change to support multiple components (just parameterize each component separately). On the GUI end, easiest to support this by just having a current "active" component (so...

A common bug in geometry processing code is that you solve a linear system Ax=b that's not actually correctly constructed, but forget to check the size of the residual r...
