tb_occupancy_grid — 2D typed op

Data kinds: pointsvolume

Call: fullseye.apply(img, "tb_occupancy_grid", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

Point cloud (N,3) → 3-D occupancy voxel grid (res,res,res) bool (voxels that points fall into are marked occupied).

> The detailed description below is the original text — the summary and the headings are translated.

`bounds=((xmin,xmax),(ymin,ymax),(zmin,zmax)) が格子の張る体積、res` は各軸の

ボクセル数(立方 res³)。ボクセルは半開区間 [lo+i/res*span, lo+(i+1)/res*span) で、

上端 (frac==1) の点は最終ボクセルに含める。bounds 外の点は落とす(端セルへ

clamp すると境界に幻の障害物が積もるため)。match3d.points_to_voxel が密度(float)

を作るのに対し、これは planning 用の占有(bool)を作る点が固有。

Raises ValueError for res<=0, non-(N,3) points, or degenerate bounds.

2-D 進化レジストリへ橋渡しした 3d の op `occupancy_grid。実装は同じで、呼び出し規約だけ op(v, a, b) に合わせてある。この op に調整点は無く、ab` も使われない。
