render op• Data kinds: points → depth
• Call: import fullseye as fs; fs.ledger.render_point_depth(points, K, size, R=None, t=None) (to call the implementation directly, import match3d; match3d.render_point_depth(points, K, size, R=None, t=None); from the registry, ops3d.get("render_point_depth"))
Point set → a depth image (z-buffer; each pixel takes the depth of its nearest point). For synthesising observations and inspection samples.

`project_points(points, K, R, t) で (u, v, z) を取り、round した画素 `(row=v,
col=u)` が size=(H, W) 内かつ z > 0` の点だけを、遠い順に書いて近い点で上書きする
(同一画素は最小 z が残る)。点が無い画素は 0(`tsdf_from_depth / depth_to_points` が
無効値として扱う規約)。返り値 `(H, W)` float64、単位は点の座標の単位。
• 1 点 = 1 画素なので疎な点群は穴だらけになる(`mesh_to_points` で密にしてから)。splat
半径は無い。
• `K は numpy (3,3)、R/t` は省略可。
後段: `depth_to_points で戻す、normals_from_depth で法線、tsdf_from_depth`。
