I just had a user ask me about how to project the shadow of a spoon shaped object onto a plane.
There is a point source some distance in front of the spoon. The spoon may not be normal to the point source or to the projection plane.
What I did for him to get a quick answer was to create points on the edge of the spoon, create curves between the point source and the points on the spoon edge. I then use those curves to create in-line points on the projection plane. The more points you create on the spoon edge the better the shadow shape on the projection plane.
Anyone have a better way to do this?
Please, there has got to be a better way!
