I need your help,
I have to create a light effect, rays of light from an object (source) which pass through the transparency of another object.
For example: a sun behind a tree. The rays of the sun pass through the branches creating lights and shadows.
Is it possible?
I have an app on iPad that generates this effect, move the source (light) where you want, set the parameters (intensity, size, etc) and it recognizes the shape of the object in front of source.
