WebGL: Animating a 3D scene

by Diego Cantor | June 2012 | Beginner's Guides

Objects in 3D scenes can have actions on their own. For instance, in a racing car game, each car has its own speed and trajectory. In a first-person shooting game your enemies can hide behind barricades then come and fight you or run away. In general, each one of these actions is modeled as a matrix transformation that is attached to the corresponding actor in the scene. These are called local transforms.

In this article by Diego Cantor author of WebGL Beginner’s Guide, we will study different techniques to make use of local transforms.

Web Services, SOA, and WS-BPEL Technologies

by Yuli Vasiliev | October 2007 | BPEL MySQL SOA Web Services Open Source Oracle PHP

Service-Oriented Architecture (SOA), as an architectural platform, is adopted today by many businesses as an efficient means for integrating enterprise applications built of Web services—loosely coupled pieces of software that encapsulate their logic within a distinct context and can be easily combined into a composite solution. Although building applications that enable remote access to resources and functionality is not new, doing so according to the principles of service orientation, such as loose coupling, represents a relatively new approach to building composite solutions.

Web Services in Microsoft Azure

by Nathan A. Duchene Richard J. Dudley | November 2010 | Enterprise Articles Microsoft

Technically, web services are part of the web role, but their use and development are so distinctly different than web forms that we'll look at these separately. The web services themselves can be written in any language supported by Azure, but utilizing the Windows Communication Foundation (WCF) libraries in .NET greatly simplifies the development of web services. The simple storage services have their own REST API and client library developed, but if we want to add data into SQL Azure, we'll have to create our own web services.

In this article by Richard J. Dudley and Nathan A. Duchene, authors of Microsoft Azure: Enterprise Application Development, we'll:

  • Gain an overview of WCF services
  • Build the WCF service for the Jupiter Motors portal
