Blendtopo - Topology Optimization

Changelog

Various code cleanups: ran Ruff checks, fixed stale docstrings, and, most importantly, included the wheels for trimesh and rtree.

Changelog

fixed version mismatch and moved all the calculations to a subprocess as to not freeze the ui.

Changelog

threading / queue removed. CuPy is removed from the hosted add-on, so it's now pure-numpy with no wheels.

Changelog

• 0.8.0 — Geometric-multigrid preconditioner (grid-independent solve speed); "Continue" to resume more iterations; final pass runs full (no early stop); Optimize Mesh now reduces vertex count with adjustable smooth/decimate; clearer error status.
• 0.7.x — Robust point-in-mesh voxelisation (fixed scattered holes); GPU self-test with auto CPU fallback; faster matvec (matmul + bincount); cross-level displacement warm-start; adaptive CG tolerance; tooltips.
• 0.6.0 — Build-space-restricted solver; centred grid; GPU status; rich tooltips; GPL license + publishing guide.
• 0.5.0 — CG warm-start; convergence early-stop; optional CuPy GPU path; Optimize Mesh button.
• 0.4.x — Smooth surface-nets preview; watertight output; results collection; background-thread solve; wireframe inputs; morph-style preview.
• 0.3.x — Coarse-to-fine multi-resolution; packaged as an extension.
• 0.2.0 / 0.1.0 — Voxeliser, matrix-free FEA + SIMP core, sidebar UI.
