ambient_occlusion — 3D `render` op

• Data kinds: mesh → image2d

• Call: import render_ao; render_ao.ambient_occlusion(V, F, pose=None, intrinsics=None, width: 'int' = 256, height: 'int' = 256, n_dirs: 'int' = 64, max_dist: 'float | None' = None, k: 'int' = 3, background: 'float' = 1.0, method: 'str' = 'auto') -> 'np.ndarray' (or ops3d.get("ambient_occlusion"))

Usage

Render the mesh into an AO map image `(H, W)` in [0,1].
