 3D camera with 4 square cameras taken pinch to see if the lines connecting the same colored dots are perpendicular to the 2 cameras squared horizontally perpendicularly with 2 cameras pointed vertically. oblique angle to 2 cameras creates 2 same color dots. connect 2 horizontal camera dots and connect 2 vertical camera dots, these 2 lines are perpendicular. so to remove the same color dots without having to have from 1 bright dot above objects to 4 cameras which are many bright dots of the same color, then connect 2 rays from 2 colored dots of the same color of 2 cameras intersect to create 3d coordinates. increase the number of dots to capture the far distance to see the distortion in the distance.To create a large lens that collects more light and remains thin, we cut the upper surface under the lens and remove the center of the lens. .Then merged the top and bottom halves into 1. this time the lens was thinner and still had the same light absorption
