+ * Post processing node for applying Screen-Space Shadows (SSS) to a scene.
+ *
+ * Screen-Space Shadows (also known as Contact Shadows) should ideally be used to complement
+ * traditional shadow maps. They are best suited for rendering detailed shadows of smaller
+ * objects at a closer scale like intricate shadowing on highly detailed models. In other words:
+ * Use Shadow Maps for the foundation and Screen-Space Shadows for the details.
+ *
+ * The shadows produced by this implementation might have too hard edges for certain use cases.
+ * Use a box, gaussian or hash blur to soften the edges before doing the composite with the
+ * beauty pass. Code example:
+ *
+ * ```js
+ * const sssPass = sss( scenePassDepth, camera, mainLight );
+ *
+ * const sssBlur = boxBlur( sssPass.r, { size: 2, separation: 1 } ); // optional blur
+ * ```
+ *
+ * Limitations:
+ *
+ * - Ideally the maximum shadow length should not exceed `1` meter. Otherwise the effect gets
+ * computationally very expensive since more samples during the ray marching process are evaluated.
+ * You can mitigate this issue by reducing the `quality` paramter.
+ * - The effect can only be used with a single directional light, the main light of your scene.
+ * This main light usually represents the sun or daylight.
+ * - Like other Screen-Space techniques SSS can only honor objects in the shadowing computation that
+ * are currently visible within the camera's view.
+ *
+ * References:
+ * - {@link https://panoskarabelas.com/posts/screen_space_shadows/}.
