Four, boundary sign filling algorithm In the raster display plane, the polygon is closed, it is a closed area surrounded by a certain boundary color, the filling is carried out by line, that is, the polygon is intersecting with the scan line, and is filled between the intersection pairs. The boundary flag filling algorithm is used to fill the boundary or boundary color as a symbol when the line-by-row proc

Description A rectangular polygon is a polygon whose edges are all parallel to the coordinate. The polygon must have a single, non-intersecting boundary. No two adjacent sides must be parallel. Johnny has several sticks of various lengths. He would like to construct a rectangular polygon. It planning to use sticks as h

We will give you a detailed analysis of photoshop software users and share with you how to create a shoe poster with the design ink splash effect.Tutorial sharing:1. Create backgroundStep 1Create a new canvas in Photoshop and set the size to 960 pixels * 638 pixels. Select the paint bucket tool and set the color to dark blue # 1f222a for filling.Copy and paste the watercolor material into the canvas, and press Ctrl + T to adjust the size of the canvas

Usually when you slice out the output of the page, generally use the common slicing tool for output. But if you encounter a lot of navigation, slicing overlap, with the general method can not be processed, then the advantages of the variable slicing tools appear, the following I will elaborate on the use of variable slicing tools! 1. Open a good navigation picture, in the first frame to do the general state graphics, in the second frame, do the button over state graphics, as shown: 2. Go bac

I have previously written an article, irregular graphic UV mapping, (http://blog.csdn.net/itolfn/article/details/17240131) used triangulation algorithm, but the algorithm is not complete, There is one rule: optimality: the diagonal of a convex quadrilateral formed by any two adjacent triangles if interchangeable, the smallest angle in the six inner corners of two triangles does not become larger. is to take four of the maximum triangular angle of the triangle to join the diagonal, grouped two tr

Good Harvest: Line Segments and straight lines are more skillful, and some details are also improved. It gives you a polygon, a straight line. Note that it is a straight line that determines the sum of the length of this line inside the polygon. It is clear that all the intersections are sorted in one direction. The line segments between two adjacent points must be either within the
