EXPERIMENTAL CONTROL. DO NOT USE.
This control adds a point light in the scene.
V: The color of the light (default range:
[0, 1]for each)
intensity: The intensity of the light. Value depends on the environment. (default range:
distance: The distance away from the object of interest
dir_x: relative (x, y, z)-coordinate of the point light w.r.t the object of interest. (default ranges:
[0, 1]respectively for x, y, z).
1. You can add multiple point lights by using this control multiple times
2. The vector
(dir_x, dir_y, dir_z)is used along which direction w.r.t the is the point light placed, but the actual distance along that direction is decided by the

Undo the modification on a scene
Most of the time, recreating a scene is very expensive, therefore, controls are asked to implement a reverse operation to undo their changes. Controls that need to store state in order to undo their actions should add data to the target object they received.
context (Dict[str, Any]) – The description of the scene to render
