- D3DX je dynamická knihovna rozhraní DirectX. Obsahuje užitečné matematické a jiné funkce (např. pro práci s vektory, maticemi, , …). Součástí knihovny jsou ovšem také speciální třídy pro práci s čárami, modely a texturami. Umožňuje např. jednoduchým způsobem načítat z disku i z paměti .x objekty a nejpoužívanější formáty textur.

- In computing, D3DX (Direct3D Extension) is a high level API library which is written to supplement Microsoft's Direct3D graphics API. The D3DX library was introduced in Direct3D 7, and subsequently was improved in Direct3D 9. It provides classes for common calculations on vectors, matrices and colors, calculating look-at and projection matrices, spline interpolations, and several more complicated tasks, such as compiling or assembling shaders used for 3D graphic programming, compressed skeletal animation storage and matrix stacks. There are several functions that provide complex operations over 3D meshes like tangent-space computation, mesh simplification, precomputed radiance transfer, optimizing for vertex cache friendliness and strip reordering, and generators for 3D text meshes. 2D features include classes for drawing screen-space lines, text and sprite based particle systems. Spatial functions include various intersection routines, conversion from/to barycentric coordinates and bounding box and sphere generators. The D3DX library contains pre-written routines for doing things common to most 2D/3D applications, such as games. Since the Direct3D API is relatively low-level, using the D3DX library is usually much simpler. In 2012, Microsoft announced that D3DX 9, D3DX 10, and D3DX 11 would be deprecated in the Windows 8 SDK, along with other development frameworks such as XNA. Shader effects, texture management, geometry optimizations and mesh models are available as separate sources published through GitHub. The mathematical constructs of D3DX, like vectors and matrices, would be consolidated with XNAMath into a DirectXMath and spherical harmonics math is provided as separate source. (en)
- D3DX（Direct3D Extension）是一个已不推荐使用的高层API库，它旨在补充微软Direct3D图形API。D3DX库在Direct3D 7中被引入，并在之后的Direct3D 9中得到改进。它为常见的在矢量、矩阵和颜色上计算外观和投影矩阵、样条插值以及其他一些更复杂的任务（诸如编译或组合用于3D图形编程的着色器、压缩骨架动画存储和矩阵堆栈）提供了类。它还为3D网格的复杂操作提供了函数，如切线空间计算、网格简化、预计算辐射传输、顶点缓存友好性优化和条带重排序，以及3D文本网格的生成器。2D特性包括绘制屏幕空间线条、基于文本和精灵的粒子系统的类。空间函数包括各种交叉例程、转换重心坐标和边界框/球生成器。 D3DX库包含众多预先编写的例程，适用于大多数2D/3D应用程序（例如游戏）所需的常见操作。因为Direct3D API相对底层，所以使用D3DX库通常简单许多。 微软于2012年宣布，D3DX将在Windows 8 SDK以及其他开发框架（例如XNA）中。着色器效果、纹理管理、几何优化和网格模型可作为单独来源通过CodePlex发布。D3DX的数学结构，例如向量和矩阵，将与XNAMath并入DirectXMath，球面谐波数学将以单独来源提供。 (zh)
