A new general rendering algorithm for conic sections is presented. Among its new features are: 1) curve tracking with no octant/quadrant change control within the main repeating loop, reducing the inaccuracy of slope evaluation for octant change procedure. Quadrant change is controlled by multiple residue sign test 2) the sign of the curvature controls the(More)
Visual Analytics is the science of analytical reasoning supported by interactive visual interfaces. People use visual analytics tools and techniques to synthesize information; derive insight from massive, dynamic, and often conflicting data; detect the expected and discover the unexpected; provide timely, defensible, and understandable assessments; and(More)
