Orthographic projection? •The first four parameters say the coordinates of the clipping window on near plane. Design Handbook: Engineering Drawing and Sketching Introduction One of the best ways to communicate one’s ideas is through some form of picture or drawing. Thus, perspective projection is very rarely used to draw engineering objects. The problem in perspective projection is due to the single station point that produces radiating projectors. Life is made much simpler when the station point is an infinite distance from the object so that the projectors are parallel. The indisputable reason why ... classifications, are parallel projection and perspective projection.
