spheres_render_shaded — DRIVE `granular` op

• Data kinds: matrix × scalar × scalar × scalar × scalar → rgb

• Call: import fullseye as fs; fs.ledger.spheres_render_shaded(pos, radius: 'float', pitch: 'float', extent: 'float', height: 'float', light=(-0.4, -0.6, 0.7)) -> 'np.ndarray' (to call the implementation directly, import granular; granular.spheres_render_shaded(pos, radius: 'float', pitch: 'float', extent: 'float', height: 'float', light=(-0.4, -0.6, 0.7)) -> 'np.ndarray'; from the registry, opsdrive.get("spheres_render_shaded"))

Usage

Renders the side orthographic projection with shading (numpy z-buffer, Lambert). For GIFs. Returns (rows, cols, 3) [0, 1].
