Compare Parallel Projection and Perspective Projection?
Expert
A) Perspective Projection:
a) The rays from an object converge at the finite distance is (termed as COP)b) It can be classified on the basis of main vanishing point it can have at most 3 and at least 1 main vanishing point that is, single point, two point and three point projection.
B) Parallel Projection:
a) The rays from an object converge at the infinity.b) It can be classified according to the angle which the direction of makes by the projection plane that is, orthographic & oblique projections, that are further, classified.
