Conceptually, drawing a straight black line in Java 2D can be thought of as creating a line segment, transforming it according to the current transform, stroking it to create a thin rectangle, querying this shape to compute the pixels being affected, generating the pixels using java.awt.Color.BLACK, and then compositing the results onto the screen.
JTS is developed under the Java JDK 1.4 platform. It is 100% pure Java. It will run on all more recent JDKs as well. [6] JTS has been ported to the .NET Framework as the Net Topology Suite. A JTS subset has been ported to C++, with entry points declared as C interfaces, as the GEOS library.
ability to draw the 1st and 2nd derivative and the integral of a plot function; support user-defined constants and parameter values; various tools for plot functions: find minimum/maximum point, get y-value and draw the area between the function and the y-axis
Binary space partitioning arose from computer graphics needing to rapidly draw three-dimensional scenes composed of polygons. A simple way to draw such scenes is the painter's algorithm, which produces polygons in order of distance from the viewer, back to front, painting over the background and previous polygons with each closer object. This ...

An important special case, in which the points are given in the order of traversal of a simple polygon's boundary, is described later in a separate subsection. If not all points are on the same line, then their convex hull is a convex polygon whose vertices are some of the points in the input set. Its most common representation is the list of ...
A model's polygons can be rendered and seen simply in a wire frame model, where the outlines of the polygons are seen, as opposed to having them be shaded. This is the reason for a polygon stage in computer animation. The polygon count refers to the number of polygons being rendered per frame.
NASA WorldWind SDK Tutorial: This Tutorial was developed by the Institute for Geoinformatics from the University of Münster, Germany. It contains tutorials from setting up an Eclipse environment with the WorldWind API to building polygons from Linked Open Data geographic datasets.
