Objective Brushes, textures, and even Photoshop noise filters can make a galaxy look, but I don't think it's nearly enough. It may not be direct enough, and it is difficult to express it completely in any shape. So, the galaxies we're drawing seem to be just the galaxies in the concept. This tutorial will teach you to use AI and PS to create a Galaxy poster, of course, if you use the stars to do the background that is too dull. This time, let's try using a low

This article describes how to make a polygon form using the making interface functions provided by Windows. The key to making a polygon form is to set the area of the polygon and change the shape of the form according to the specified area. Windows CREATEPOLYGONRGN and SETWINDOWRGN functions can solve both of these difficulties. You can set the form to a Pentag

Under normal circumstances, just press the Edit Collider button, the mouse stops at the edge of the Polygon Collider 2D, a virtual new vertex will appear, at this point, if you press the mouse, the new vertex is created.But I have a strange situation today is the mouse on the edge of the Polygon Collider 2D, does not appear the virtual new vertex, click does not create a new vertex. Later found that the sca

if This 3 and at the mosta -10,000 to a. Assume the polygon formed by given points are always a simple polygon (simple polygon definition). In the other words, we ensure that exactly the edges intersect at all vertex, and that edges otherwise don' t intersect E Ach other. Example 1: [[0,0],[0,1],[1,1],[1,0]]answer:trueExplanation:2: [[0,0],[0,10],[10,10],[10,0]

Convex Polygon diameter We define the maximum distance between any two points on a polygon as the diameter of the polygon. The number of vertices that determine the diameter may be more than one pair. In factNPolygon of a vertex may haveNThere is a "diameter point. A simple example of a polygon diameter is shown

Today I saw an interesting article about how to implement polygon search. In fact, it is to determine whether a point in the coordinate system is inside the polygon. Polygon search is still very useful, such as searching Hotels and Restaurants in a certain area. This is another mathematical problem. It can be expressed simply by Graph Theory: to determine whether

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

A Method for Extracting polygon from a texture image. I have been writing a blog here for a long time. In many cases, the texture image and the polygon match are often complicated to manually set. Therefore, a code is written to extract the edge polygon from the texture image. However, this code can only extract "solid" polyg
