Matrix, Euclidean angle, axis-angle pair, and Quaternary Element

I. MatrixIn 3D games, a matrix can be used to represent the rotation of an object.1) Advantages:In my opinion, it is the most intuitive to understand.Similar to the existing dxsdk library, related interfaces are also provided.A matrix represents a combination of multiple transformations.2) Disadvantages:Errors are generated during each calculation. Therefore, normalization is required frequently.More memory consumption.Ii. ouarlaOuarla refers to the reference coordinate system based on the world

OpenGL Observation axis

The rotation matrix can be constructed by observing vectors, which can be two or three points in 3D space. If an object at Point P1 faces point P2, the observed vector is the P2-P1, for example: First, the forward axis vector is simply calculated using the normalized observation vector. Secondly, the Left axis is calculated by specifying the difference between the vector in the upward direction and the for

Axis-based custom object serialization

Recently, because the company used Web Services technology for Enterprise Application Integration (EAI)-related projects, the use of axis in response to technical staff cannot pass user-defined objects. The error message is as follows:AxisfaultFaultcode: {http://schemas.xmlsoap.org/soap/envelope/}server.userexceptionFaultsubcode:Faultstring: Java.

Principle and composition of four-axis aircraft

Principle and composition of four-axis aircraftBefore we actually start making four-axis aircraft (four-rotor), let's take a look at the basic composition and principle of the four-axis aircraft. In addition to understanding the necessary theoretical principles, it is also necessary to know the four parts of a four-axis

Differences between RPC and RMI and the connections and differences between Ajax-rpc, jax-ws, axis, and xfire

Method built on the TCP/IP Protocol. RMI call Mechanism RMI uses stubs and skeletons for remote object communication. Stub acts as the client proxy for the remote object and has the same remote interface as the remote object. The call to the remote object is actually done by calling the client proxy object stub of the object. Jax-rpc, jax-ws, axis, and xfire connections and differences Sun and Java standards JAX-RPC 1.0 is the original standard

Conversion Between the Quaternary element and the angle-and-axis pair

In 3D graphics, the most common rotation representation method is the four-element and the Euclidean angle, which saves storage space and facilitates interpolation compared with the matrix. This article mainly summarizes the conversion of two expressions. The calculation formula uses the 3D Cartesian coordinate system: Figure 1 3D Cartesian coordinate system (from Wikipedia) It is defined as the rotation angle around the Z axis, Y

Axis generates Java client code based on WSDL

There are several ways to generate Java client code based on WSDL, where the code generated by using axis is more friendly and is often used as a method. First download the Axis jar package: Axis-bin-1_4.zipOfficial address: http://ws.Apache.org/axis/as if the official download can not, provide under my Baidu cloud: Ht

axis framework. Axis is widely used, including developers downloading and using it directly, and embedding it into several different application servers as a SOAP engine. Axis is generally considered to be the most widely used Java soap web service platform. However, axis also has some disadvantages. First, it was des

Axis and cxf of the WebService pop frame

Transferred from: http://www.cnblogs.com/snake-hand/archive/2013/06/09/3129915.htmlObjectiveIn the last lesson , we gave a brief introduction to WebService, and we have a certain understanding of the technology applied to it. Today the main explanation is the two popular frames of the WebService Axis and the CXF. BusinessFirst, the service side release WebServiceBefore we talk, let's take a look at what this blog mainly explains:Each framework has i

Moving the axis photography, generally refers to the use of moving axis lens creation works. This kind of photography, known as the "Eye of God," is a very special piece of work, like a miniature model. Usually we use the axis-shift lens to achieve this effect, the axis-shift lens is mainly used to modify the normal wi

Using axis, it is very simple to publish a web service. Although the process and relatedCodeLong. I used these software in this post: Axis 1.1, eclipse 2.1, and eclipse Tomcat plug-in 2.2 (sysdeo Tomcat plugin ). The release method is as follows: The service I want to publish is a library store. The publishing methods include adding books addbook, listbooks, and deletebook. For the sake of simplicity, onl

Use Apache axis to implement Web Service (1)

The advantages of web service are not nonsense. If you do not know, this article is not suitable for you. Apache axis is the third-generation version of Apache SOAP, and far exceeds the latter in terms of running speed, flexibility, and stability. More importantly, axis supports the Web Service Description Language (WSDL), which is the most widely supported Web Service Description Language Specification de
