SDF for a 2D rectangle with optionally rounded corners.

Each corner has a separate roundness setting, which can be used to make some corners round and others sharp.

See ShaderToy for example.

Parameters

• Scale: The size of the rectangle along the X and Y axes.
• Roundness: The distance of rounding for each of the four corners. When the roundness exceeds half the `Scale`, the rectangle will have discontinuities along the axes.
• Roundness Unit:
  • Distance:
  • Ratio of Scale:
