Windows Process Description:

The d3dx9_30.dll module as part of a number of Direct3D extensions for DirectX is a high level API written to enhance Direct3D graphics. It contains pre-written routines for doing common application to most 2D and 3D applications such as games.

The d3dx9_30.dll module provides common calculations on matrices, colors and vectors, calculating look-as and projecting matrices, and spline interpolations. It also provides common calculations for complicated tasks such as compressed skeletal animation storage, compiling or assembling shaders used for 3D graphic programming and matrix stacks.

The application d3dx9_30.dll includes several simple functions that provide complex operations over 3D meshes like mesh simplification, optimizing for vertex cache friendliness and strip reordering, tangent-space computation and generators for 3D text meshes. For 2D features, the module supports classes for text and sprite based particle systems and drawing screen-space lines. It also supports spatial functions that include conversion from/to barycentric coordinates, bounding box/sphere generators and various intersection routines.

The d3dx9_30.dll module is introduced first in Direct3D 7 and has been improved for Direct3D 9 in which the number 9 was derived. This DLL is used only for speeding up the development process and is not intended to replace the functions of Direct3D.

Direct 3D is the base graphics API of most Microsoft's applications designed to render both 3D and 2D graphics in the operating system. It uses hardware acceleration for the entire 3D rendering pipeline, if it is available on the graphics card. The d3dx9_30.dll module latest version can be found on DirectX 10 and has the file size of about 2.28 MB.
