Monitor Lighting

"Monitor" refers to a rectangular texture light. In Kanikama, the diffuse lighting of a monitor is implemented by dividing the monitor into rectangular blocks (e.g., 2x2, 3x3) and treating each block as a single light source. This idea is essentially same as¹.

In the next image, the monitor is divided into 3x2 blocks.

The averaged color of each block is calculated by capturing the monitor image through the Camera component and sampling it at its appropriate mipmap level.
