Polygon buffering algorithm
Did you know?
The fundamental method to create a buffer around a geographic feature stored in a vector data model, with a given radius r is as follows: • Single point: Create a circle around the point with radius r. • Polyline, which consists of an ordered list of points (vertices) connected by straight lines. This is also used for the boundary of a polygon. WebWith this data structure in place, the z-buffer algorithm proceeds much as the heedless painter visiting each polygon in turn, but with one crucial difference: A pixel is overpainted -- that is, a new color or intensity is stored in the z-buffer -- only if depth of current polygon at pixel < current depth of pixel in z-buffer
WebThe z-Buffer Algorithm. The z-Buffer algorithm is one of the most commonly used routines. It is simple, easy to implement, and is often found in hardware. The idea behind it is uncomplicated: Assign a z-value to each polygon and then display the one (pixel by pixel) that has the smallest value. WebBuffer / Overlay module is a simple GIS module, this module allows you to generate Buffer from point, line or polygon data and perform Overlay operations between polygons with …
WebThis algorithm provides a "best-effort" interpretation. In particular: For self-intersecting lines, the buffer boundary includes offset lines for both left and right sides of the input line. Only … WebMay 10, 2009 · From following the steps outlined, I can create polygon shapes around simple lines that do not cross themselves or have too tight curves, but as the lines I'm …
