title
A Note : An Interactive Procedure for Constructing Line and Circle Tangencies
source
IEEE Computer Graphics and Applications. April, 1986. vol. 6: pp. 59-63 : ill. includes bibliography
summary
This note describes a procedure that enables a designer or draftsperson with limited mathematical training to discover interactively the construction of a wide variety of tangency and intersection problems. Requiring very little code to implement, it supplements the standard tangency constructions available on commercial turnkey computer-aided-design systems with a flexibility unavailable even through the inclusion of the numerous special-purpose algorithms available in the literature
