surfacewhere
Surfacewhere is a term used in computational geometry and computer graphics to describe a framework for locating and characterizing locations on one or more surfaces where a specified condition holds. It typically involves determining the locus of points that satisfy a set of surface equations or constraints, such as intersections of surfaces, tangency, or thresholded values of scalar fields defined on a surface.
In practice, surfacewhere can operate on implicit representations, parametric surfaces, or polygon meshes. It combines numerical
Applications include computer-aided design, visual effects, collision detection, mesh repair, and shape analysis. The concept helps
