phong_shade — 3D `render` op

• Data kinds: normalmap → image2d

• Call: import render_shade; render_shade.phong_shade(normals, view=(0.0, 0.0, 1.0), light=(0.0, 0.0, 1.0), ambient: 'float' = 0.1, diffuse: 'float' = 0.8, specular: 'float' = 0.5, shininess: 'float' = 32.0, clip: 'bool' = True) -> 'np.ndarray' (or ops3d.get("phong_shade"))

Usage

Shade a normal map with the Phong reflection model (ambient + diffuse + specular). → `(H, W)`.
