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;

The rules for walking are X or y plus their least common multiple LCM (x, y).Consider (ex, EY) is coming from other points, it is advisable to set when walking to (x, y), GCD, =K,X=K*M1, y=k*m2.The next step may be (x, Y+X*Y/GCD (x, y)) or (X+X*Y/GCD (y), y).denoted by K and m1,m2 (k*m1, k*

GraphicsEnvironment class saves the graphic objects and a set of colors, including the width and height. The saveAsPng method outputs the current image to a specified file. GraphicsObject is a required interface for any graphic object. To start using this interface, you must use the render method to draw this object. It is implemented by a Line class. it uses four coordinates: the x value of start and end, and the y value of start and end. It also has a color. When render is called, this objec

plain text and pronunciation Lexicon specification (PLS) format. Several examples show how to store the custom dictionaries in PLS format and extract the data into the normal file that you want. Example: Dictionary A dictionary is a list of words used in speech recognition tools. They contain information about how to print or display a word in a graphic, and how it uses phonemes to pronounce. Dictionaries that are often used with Hidden Markov Model Toolkit (HTK) are widely used in speech con

N points, M edge, the edge is divided into a, b two classes, to construct a minimum spanning tree, and the number of a side of the tree is K.We can control the number of a edges in the tree by adding a weight dx to all a edges.
