json transformation

Conversion combination Imagine an object in any direction and position in the world. We want to render it to a camera in any direction and position. To achieve this, all vertices of an object must be transformed from the object coordinate system to the world coordinate system, and then from the world coordinate system to the camera coordinate system. The mathematical transformations are summarized as follows: Matrix Multiplication satisfies the combination law, so we can use a matrix to directl

The K-L transform (Karhunen-loeve Transform) is a transformation based on statistical characteristics, some of which are referred to as hotelling (Hotelling) transformations, since he first gave the method of transforming discrete signals into a series of unrelated coefficients in 1933. The outstanding advantage of the K-L transformation is that it is good to correlate and is the best

It is based on a subset of ECMAScript. Because it adopts a language-independent text format and also uses a habit similar to the C language

OpenGL through the camera simulation, can achieve the most basic three-dimensional transformation of computer graphics, namely, geometric transformation, projection transformation, clipping transformation, viewport transformation, and OpenGL also realizes the Matrix stack an

Http://blog.csdn.net/bailang71/article/details/1966158 Windows form programming coordinate system type GDI + uses three coordinate spaces: World, page, and device. World coordinates are the coordinate systems used to establish special world models in graphics. They are also the coordinate systems passed in. NET Framework. The page coordinate system refers to the coordinate system used by a drawing (such as a form or control. The device coordinate system is the coordinate system used by a physic

Basic geometric transformation and Transformation Matrix Basic ry transformations are geometric transformations relative to the coordinate origin and coordinate axes, including translation, scale, rotation, reflection, and miscutting. 1.1 translation Transformation It refers to the p

C # is a strong language. In general, we 'd better avoid forcibly converting a type to another type. However, sometimes the type check during running is unavoidable. I believe you have written many functions with the system. Object type as parameters, because the. NET Framework defines the signatures of these functions in advance. Within these functions, we often need to transform those parameters down to other types, classes, or interfaces. For this transfo
