ACIS(R) is object oriented, boundary representation geometric modeling toolkit, written in C++, designed to be used as the "geometry engine" for next generation applications. ACIS provides an open architecture framework for wireframe, surface, and solid modeling. Linear and quadric geometry is represented analytically, free-form geometry is represented NURBS. ACIS supports manifold and non-manifold topology as well as bounded, semi-bounded, and unbounded geometry. ACIS capabilities can be accessed through its Applications Procedural Interface, or developers writing in C++ can add, derive, or extend classes. ACIS can be licensed as object code and full source code.
