# llimphi-mesh

Rendering of deformable meshes to a `vello::Scene`.

The bone and skinning maths live in `llimphi_anim::skel`; this crate only
**paints** the already-deformed mesh. It receives the mesh (`Mesh`) plus the
deformed positions of its vertices (what `Mesh::deform` returns) and a
model→screen `xform`, and offers the two routes the spike validated against
vello 0.7:

- `paint_solid` — fills each deformed triangle with a colour (vector mesh /
  debug). Trivial.
- `paint_textured` — a **textured** mesh: per triangle, it clips to the deformed
  triangle and draws the image with the affine mapping its UVs to the deformed
  position (piecewise-affine warp). Cost = one clip layer per triangle; careful
  with meshes of thousands of triangles.
- `paint_wireframe` — strokes the triangle edges (to see the deformation; ideal
  for demos and debugging).

Framing helpers: `rest_bounds` (the mesh's bbox at rest) and `fit_transform` (the
affine fitting those bounds, centred, into a `PaintRect`).
