intersect . . . invisible images

[Mark Waddingham]

As I attempted to explain (clearly not very well!) intersect uses the transparency of pixels of the object when rendered in isolation to determine what parts of the object should be used to check for intersection.

For example, you might have an image which incorporates a mostly transparent drop shadow. By choosing an appropriate threshold, the shape which actually gets interacted in that case can be everything but the drop shadow.

Hopefully they fully intersect most of the time unless you are sleeping or actively astral traveling. (Not a good idea for the untrained)   but I would change the coloir scheme, substitute "light blue" for invisible (some people, children, cats *can* see them)  and it’s the same thing.  then when you die, all you just "delete" the first two objects (food body, energy body)  (ha!)
