Practical Issues in Graphical Constraints
Use of constraint-based techniques in interactive graphics applications poses a variety of
unique challenges to system implementors. This paper begins by describing how interface
concerns create demands on interactive, constraint-based, graphical applications. We will
discuss why such applications must be able to handle systems of non-linear constraints, and
survey some of the techniques available to solve them. Employing these numerical algorithms
in the contexts of interactive systems provides a set of challenges, including dynamically
setting up the equations to be solved and achieving adequate performance and scalability. This
paper will explore these issues and describe the methodswe have used in our efforts to address
them.
