I would suggest however that it would be easiest to create a shadow for each block independently, rather than considering the whole combined shape.
It would also seem as though the furtherest two points were the only ones you would need to figure out based on your game world boundary coordinates.

however in my experience of making a game I found it easier to consult a basic school textbook for trig functions. Cause it was well written and and easy to follow
