I need to find all points that are on a line. I tried Bresenham\'s algorithm but it doesn\'t work on the following case:
Given a cubic polynomial estimated using least-squares regression, I am interested 开发者_运维技巧in a simple algorithm that rasterizes the curve to display in an image. My initial intuition is to sam
Is there a modifi开发者_JAVA技巧cation of Bresenhman (or any) algorithm to draw line with defined line width? I can only use DrawPoint(x,y) function. And second question: how to implement filling a fi
This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time,or an extraordinarily narrow situation that is not generally applic
I have created a whole heap of overlays using MKPolygon and created into a MKPolygonView. This works fine but one of the overlays has a butt load of points (about 800 points) and this causes memory an
I am planning to write a SVG player. To have the animation run at 20 frames/second I want to generate images at that rate and throw it at the开发者_JS百科 screen.
