below are each of the events as well as a short step by step explanation of the process so far.
whenever a room with a solid surface is loaded, a global object creates this object_TDS (three dimensional system). It sets itself above every other object in the room and then calls for a lot of different values but the most important ones right now are shader_TDBlock, the surfaces, and intensity.
beneath that wOff and everything beneath it is also important for the processing, image shifting and such.
