Abstract: Given a collection of segments in the plane, if we regard the segments as opaque barriers, their upper envelope consists of the portions of the segments visible from point (0, +/spl infin/).

Abstract: Depth estimation using vanishing points is important in computer vision and has been widely used in various applications such as robotics and autonomous driving. A vanishing point is a point ...

Learn all about writing the equation of a line. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e., there are no exponents in its variable(s)). There are various ...

In geometry, parallel lines are straight lines that run alongside one another and never intersect. They share a common trait, which is that they maintain a constant distance between them. Determining ...

Reporting of segment set intersections is one of the fundamental problems of computational geometry. This library implements Ivan J. Balaban's Intermediate Algorithm for finding intersecting segment ...

This folder contains Attribute Rule Calculation expression templates and functions that may be used in the attribute-rule-calculation profile. Each expression lives in a Markdown file, which contains ...
