I would like to create a light source in my scene that duplicates the effect of a projector.
The projected image will be mainly static. The projector should have 57 degrees width and 42 degrees height in terms of its field of view. How can I do this?
The reason I need to do this is in order to simulate projecting a pattern onto a face that is moving so that I dont need to have an actual projector and a real person to do my research!
