Recently there has been no time to write a blog, things more, quiet heart, things go with its natural good, and some things I do not understand why it will become so, you think you pay the most precious, but perhaps others do not like. Forget it, do not think much, let it be natural.Java does not keep up with C + + in graphic drawing, but I think Java has some advantages in graphics, but for large desktop g

Java Basics _ Inner classes: In Java, a class can be defined inside another class or inside a method, such that a class is called an inner class.The primary role of inner classes: using internal classes can reduce naming conflicts.Define location: An inner

This article is my tutor when the topic, I hope there is no copyright issues. This is a simple example of C + + class inheritance, the inheritance relationship is a graph----triangle---------------------rectangle----square, which also includes such classes as fill graphics, and shows polymorphism.Note that this program needs to be compiled with a compiler that supports c++11 , such as Vs2013,dev C + +, etc.

quaternion Euler (Vector3 Euler); public static quaternion Euler (float x,float y,float z); The method is used to return the four-quaternion q (QX,QY,QZ,QW) corresponding to the Euler angle Vector3 (Ex,ey,ez). The corresponding relationship is as follows: Known PIover180 = 3.141592/180 = 0.0174532925f is a constant light in computer graphics, and its transformation process is as follows: ex = ex * PIOVER180/2.0F; EY = ey * PIOVER180/2.0F; EZ = EZ *

A passage in Java programming thought:When writing a Java source code file, this file is often referred to as a compilation unit (sometimes referred to as a translation unit). Each compilation unit must have a suffix name. java, and within the compilation unit you can have a public class that has the same name as the f

To use PHP to generate thumbnail images, make sure your PHP server has a GD2 graphics library that uses a class to generate thumbnail images of the pictures 1. How to use $resizeimage = new Resizeimage ("Picture source file Address", "200", "100", "0", "thumbnail address"); Just use the words above, you can generate thumbnails, where the source file and thumbnail address can be the same, 200,100 re

The Abstract Windowing Tool (AWT) provides API programming interfaces for graphical user interfaces, allowing Java to provide a better graphical user interface. AWT divides the graphics processing into two layers: one is to process the original graphics, to draw the interface directly in the form of a point line, and the other is to provide a large number of comp

Defined Public Vector3 Eulerangles{get;set;} How to change the rotation state of a game object, we can change its transform to the order of Euler angle transformation, for example, suppose P (x,y,z) is a point on a gameobject, rotates a corner around the x-axis, rotates
