Application of projection transformation and surface transformation in descriptive geometry

Na Gong

Abstract

Describes the essence of transforming surface which replaces the projective reference frame where geometric elements exist to make all geometric elements exist in the two projective reference frames with a public projective panel and simplifies the drawings through one or two times continuum not only in resolving points or lines but also in doing complicated exercises.
