ACM TRANSACTIONS ON GRAPHICS 1996年 第3期15卷 223-248页
作者: Fortune, S VanWyk, CJ DREW UNIV DEPT MATH & COMP SCI MADISON NJ 07940 USA
Geometric algorithms are usually described assuming that arithmetic operations are performed exactly on real numbers. A program implemented using a naive substitution of floating-point arithmetic for real arithmetic c... 详细信息
