Manipulation and interrogation of shapes Examples: “What is the intersection of a line and a triangle mesh” “What is the minimum distance separating two objects” “Break a mesh into pieces” A typical input to a problem is some set of points or segments in the Euclidean plane (or higher dimensional Euclidean space). Schedule of all lectures, tutorials, and home assignments: PDF [20.10.2015] There is a mailinglist. Tutorial: Exact Numerical Computation in Algebra and Geometry. Computational geometry is the study of efficient algorithms for solving geometric problems. using comput-ers). The ﬁeld of computational geometry developed rapidly in the late 70’s and through the 80’s and 90’s, and it still continues to develop. The Wolfram Language's strengths in algebraic computation and graphics as well as numerics combine to bring unprecedented flexibility and power to geometric computation. If you have two vectors (x1, y1) and (x2, y2), then, the sum of the two vectors is simply (x1+x2, y1+y2). effective computational geometry for curves and surfaces mathematics and visualization Oct 08, 2020 Posted By Frank G.
