What is the optical illusion(?) where the sun’s rays appear to hit the ground at different angles through partial clouds?
The artist side of me knows that when drawing, you have to take into consideration the light source and draw shadows accordingly. So, if I were to draw a scene with the sun, the light rays would radiate outwards from that 1cm circle in the sky.
The logical side of me knows that the sun’s rays that are hitting the earth are parallel. So if I drove to the places where the sun was shining through the clouds, only a couple of km apart, the shadows would not be at different angles.
I just can’t reconcile the two.

Various conditions like heat changes and humidity can cause light to bend. This is why you get that hazy mirage in the air above blacktop in direct sunlight. So a cloud can bend light that little bit to give the “God Rays” effect.
