This tutorial introduces the low polygon Galaxy style poster tutorials that use Photoshop to design fashionable and concise low polygon Galaxy styles. The results produced by the tutorials are really beautiful and creative, and the tutorials are not very difficult, we recommend that you go to the foot home. if you like it, you can follow the tutorial to learn the

Preface
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 usi

The question is not difficult. We still use the vector cross product to see the figure.
Next, you only need to judge the relationship between one side and one point counterclockwise. If the cross product is greater than 0, it indicates that there is an inner angle greater than 180, that is, a concave polygon.

Polygon Fill Areaa polygon (polygon) is mathematically defined as a planar shape described by three or more coordinate positions called vertices, which are connected sequentially by edges (edge or side) called a multilateral nature . further , geometrically requires that the edges of polygons have no common points other than the endpoints . Thus, by definition, a

Polygon Table objects in a scene are generally described by a set of polygon patches. In fact, graphics packages often provide functions that describe surface shapes in polygonal meshes. A description of each objectincludes geometry information and other surface parameters (such as color, transparency, and light reflection properties) that specify polygon patch

Split Concave polygonOnce the concave polygon is identified, we can cut it into a set of convex polygons. This can be done using the edge vector and the edge cross product. We can use the relationship of vertex and edge extension lines to determine which vertices are on one side and which vertices are on the other side. In the following algorithm we assume that all polygons are on the XY plane. Of course, the initial position of the polygons described

The fifth chapter of this book is very good B. It describes a series of Theorem related to the inner graph of polygon and its proof. Interestingly, it is also a research on the interior drawing of polygon. When the research objects are different, the methods of proof are also brilliant, and it is very rare that, these proofs are of great value. After reading these clever proofs, I can't wait to share them w

DescriptionA closed polygon is a figure bounded by a finite number of line segments. The intersections of the bounding line segments is called the vertices of the polygon. When one starts at any vertex of

shading materials, such as Low-polygon (see yourself: To help you quickly create low-poly style of cool station recommended), mottled cement texture, if the girl's words, such as flowers can also be ... These materials will be of great use later and can be counted as basic material.
All of these are generic materials. Campus posters are often linked to the characteristics of the school itself, therefore, the school's logo, calligraphy, schoo

Then, we want to ask: Can an inner rectangle be found in any polygon? Interestingly, the answer is yes. But now, the two methods we used in the previous section are useless, and we need to use new methods. The following proves that it is actually a strange thing. I really don't know who came up with it.
For any two points A (x1, Y1) and B (X2, Y2) on the boundary of a polygon, make the points (X1 + x2)/2,

OpenGL Polygon Fill Area function (bottom)In addition to the primitive functions of triangles and general polygons, OpenGL can also describe two types of quadrilateral. the display results of Figure 3.57 (a) can be generated using the Gl_quads entity constant and the 8 vertices specified in the following two-dimensional coordinate array. Glbenin (gl_quads); Glvertex2iv (p1); Glvertex2iv (p2); Glvertex2iv (p3); Glvertex2iv (p4); Glvertex2iv (p5); Glver

Main topic: RTAnalysis: The so-called kernel can be understood as the existence of points in the polygon can be seen at this point within the polygon all the parts, of course, how to find out is the key to the problem. We know that each edge of the polygon is a boundary value, the left and right side of the edge must be part of the

Article Description: we have introduced 2013 years of Web design trends have flat design (Flat), striped web design, and so on, which Flat design is the most popular, but recently, designed to find a new design trend-polygon style, what is the polygon style? In fact, it is a bit like a white paper style, if you do not understand, below we introduce a polygon imag

When We further consider the inner diamond, there are some changes -- it turns out that the inner diamond in any polygon is not as easy as the first few problems. However, we can easily prove a relaxed proposition: arbitraryConvex PolygonThere is an inner diamond. The two different proofs of this proposition are given below, both of which are quite classic.
Proof 1: considering that a horizontal line segment in a convex

Given a list of points so form a polygon when joined sequentially, find if the polygon is convex (convex polygon Defini tion).Note:
There is at the least 3 and at the most points.
Coordinates is in the range-10,000 to 10,000.
Assume the polygon formed by given points are always a simple

We used two clever methods to prove this proposition: arbitraryConvexThe polygon contains an inner rhombus. Using the climbing theorem we talked about last time, we can prove a stronger proposition:Arbitrary PolygonThere is an inner diamond.
The general idea of proof is as follows: select a point u outside the polygon. Write the point closest to U on the polygon
