Adaptive Resampling

When a path is drawn through a non-linear coordinate transform, a straight segment in data space becomes a curve on screen. Adaptive resampling subdivides segments just enough to render that curve smoothly without over-tessellating. This essay will document GoFish's implementation.

Planned contents

• The problem: straight segments curve under coordinate transforms.
• GoFish's adaptive algorithm, adapted from D3's d3-geo resampling, generalized beyond spherical projections and extended to bezier PathSegments.
• The subdivision criterion and how tolerance is chosen.
• Interaction with coordinate transforms.
