v0.2.1

0.2.1 (2026-10-24)

Changed

• The soft body pass skips the shapes no particle can reach. Each
  substep it tested every particle of every soft body against every
  shape in the world. It now first tests the box around a soft body's
  particles against each shape: a bounding sphere for spheres, capsules,
  voxel chunks, meshes and height fields, and a separating face for
  hulls. Planes are always tested. Each test keeps a stated rounding
  margin, so a skipped pair is one the projection would leave alone. A
  bench scene of four cloths and two jellies among 2000 static shapes 40
  to 90 m away runs on 3.57 billion instructions instead of 282.1
  billion, 79 times fewer. The skip changes no result: hashes,
  snapshots and replays are the same with it as without it, and there is
  no API change. (#47)
• The API reference lives on the documentation site. The README and
  the Godot binding's README link
  https://rawframe-project.github.io/maul3d/api.html, which is built from
  the headers. The committed docs/api.md, which showed an older API, is
  gone. m3World_Hash's doc now lists what the hash covers and what it
  leaves out: mesh geometry and height field samples are not hashed.
  m3Counters.voxelEditsRefused is documented as a counter that is
  neither hashed nor snapshotted.

Fixed

• Soft body particles collide with thin mesh triangles and with
  triangles that repeat a corner; they used to pass through. On a
  triangle well under a millimetre wide, the closest point could come
  out up to a metre from a particle a few centimetres away, so the
  particle was not pushed. A triangle whose first two corners are one
  vertex gave no closest point at all. On other triangles a result
  changes only where the point lies within rounding of an edge, and no
  golden or bench result moved.
