PPT-Normal Estimation and Clipping Methods

Images were taken from the book Interactive Computer Graphics by Angel and Shreiner Normal Vectors How to compute the normal per planar face   Normal Vectors However vertex normals are not well defined. What is the idea behind modeling real world phenomena Mathemat ically modeling an aspect of the real world enables us to better understand it and better explain it and perhaps enables us to reproduce it either on a large scale or on a simpli64257ed Point Clouds. 2D/3D Shape Manipulation,. 3D Printing.
