DirectX SDK (DirectX Software Development Kit) is a set of tools consisting of all the DirectX programs and tools necessary for the development of DirectX games. It allows game developers to take total advantage of DirectX programs to create fascinating graphic applications and games. It also enables game developers to use the most recent innovations in hardware.
The key tools that compose DirectX SDK are DirectX SDK libraries and headers, DirectX API (Application Programming Interface) Documentation, DirectX runtimes, source codes, and sample applications. Previously, DirectX SDK was updated every two months with improved tools and additional samples. Just recently, Microsoft has started releasing updates four times a year.
Beginners using DirectX SDK should begin with the DirectX documentation pages and samples to learn more about this technology and its interesting techniques. Experienced game developers should also check on the “What’s New” section of the documentation file for up-to-date news and tips.
One of the vital features incorporated in the DirectX SDK is the D3DX (Direct 3DX) library. It is a toolkit offering advanced functionality. It integrates both the basics, such as low-level routines and math, and advanced technology for controlling art content. Updated mechanisms include Pre-Computed Radiance Transfer (PRT), mesh optimization, and tangent frame generation.
The D3DX Effects Framework and the High Level Shading Language (HLSL) enable graphic and game developers to employ state-of-the-art technology in shading. D3DXsamples. It also shows how to create exquisite visuals. Newer DirectX SDKs contain more samples that aid developers in learning more about Windows localization, security, configuration, and many others.
Another remarkable element incorporated in DirectX SDK is PIX for Windows. It is an application that helps developers assess their application and verifies if the use of D3D is maximized. It enables developers to test out each graphic and to visualize the setting.
Some of the most recent updates incorporated in DirectX 9.0 SDK are XInput, Microsoft Cross-Platform Audio Creation Tool (XACT), Direct3D 10 Technology Preview, and a Beta version of Windows Vista Game Explorer.
