Factory Building 3D with Variable Exposure (remix)

Description

TurboWarp recommended for higher resolution and FPS: https://turbowarp.org/805583867 This is an experiment with automatic "exposure" adjustment to make it more like a real camera or eye is viewing it. The way I did this was count the total amount of light on the screen (here it's a little hacky - just the average of the green channel). For the fake exposure, the RGB values are multiplied by a factor that adjusts based on the brightness measured. It'd be better if the brightness was measured based on the pixels at the center of the screen but I couldn't think of a performant way to do it. One limitation of the method I've used is drawing triangles over others will add further brightness but in this case it's not that significant due to backface culling and a lack of geometry behind the walls. WASD to move. Arrows or mouse to look around. 1,2,3,4,5,6,7 keys to choose resolution. 0 to toggle free cam M to cycle through view modes I moved the camera in this remix to show the exposure better. I also made a hard-coded adjustment to the sky, pushing it to 500 rather than 255 for extra brightness.
