Parallel Projection and Perspective Projection

Question

Compare Parallel Projection and Perspective Projection?

Answer 1

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.
