Witkin A. Physically Based Modeling. Principles and Practice 1997 torrent

Textbook in PDF format

In recent years, physically based modeling has emerged as an important new approach to computer animation and computer graphics modeling. Although physically based modeling is inherently a mathematical subject, the math involved needn't be any more difficult nor esoteric than the math that underlies many other areas of computer graphics, such as ray tracing or surface modeling. Many papers on the subject have presupposed a specialized mathematical background that many members of the computer graphics community lack. Consequently, many capable computer graphics practitioners, despite their interest in the subject, have simply been put off by the density of the math.
This course course addresses the need to make the principles and methods of physically based modeling accessible to a broader computer graphics audience—those who are familiar with mainstream computer graphics and have the usual basic computer graphics math, such as vector/matrix manipulations, but whose first year calculus course may be only dimly remembered.
The course is divided into two broad sections: A series of five lectures that together form a systematic exposition of the core technical content; and a pair of lectures that discuss production experience with physically based modeling techniques
