I've done up a basic image of my scene.

Basically I'm unsure of how to plot the cast shadow of the falling bomb over the slanting roof and/or the ground beside the house.

I know how to plot the cast shadow of a floating object above a flat ground plane but can't figure out how to do it on a slanting surface like a roof.

I'm aware that the bomb might have to be moved in order for me to get the cast shadow over the roof that I'm looking for but I can do that once I figure out how I should be proceeding with things.

I'd be eternally grateful to anyone who can help me out with this one

Thanks!
