Application of Spatial Perspective Affine Transformation in the Orthographic Projection
Hua Zhong, Division of engineering grahigs
Spatial perspective affine transformation is a method solving spatial geometric problems. This method may extend the field of solving problems on the descriptive geometry. This paper describes establishment of spatial perspective affine transformation in the orthographic projection, and how to find the line of section of plane with quadric surface and line of intersection of two quadric surfaces by using of the spatial perspective affine transformation.
