When designing a projection system for an auditorium, what are the PRIMARY design considerations?

The primary design considerations for a projection system in an auditorium include the viewing cone, viewing distance, and viewing angle. These factors determine the optimal placement and size of the projection screen to ensure that all audience members have a clear and comfortable view. The viewing cone defines the area in which the screen can be clearly seen, the viewing distance impacts the size of the text and images, and the viewing angle ensures the image is visible without distortion from various seating positions.
