	Direct3D vs. OpenGL: comparison
		Microsoft defines the Direct3D API through its COM interfaces, and the semantics are defined by the the help files and sample code accompanying the software development kit provided by Microsoft.
		Direct3D first appeared in DirectX 3 with execute buffers as its display paradigm.
		Hierarchical display lists are not provided by Direct3D, but Direct3D does provide storage for polygon vertices and vertex indices to avoid data copying.

	GameDev.net - An Overview of Direct3D
		Direct3D constitutes one of the emerging APIs from Microsoft Corporation, for providing new software features to developers, so that new and existing features of the PC can be exploited much better than is possible presently.
		Direct3D is available to the developer as an API, using which, applications utilizing 3D graphics can be developed much faster using a standard way.
		Though we have said uptil now that Direct3D can be used to display 3D data and though it is possible to generate 3D data on the fly, it is very difficult and restrictive to store information of various complex models and scenes, typically used in 3D systems, directly inside the application.

	Beginning Direct3D 10 Programming (Site not responding. Last check: )
		In Direct3D 9 this could be done quite simply by specifying the Flexible Vertex Format (FVF) discussed earlier, pointing Direct3D to the correct vertex buffer object and issuing a draw call.
		The IA stage is a refinement on various pieces that existed for the programmable pipeline found in Direct3D 9, and is effectively the first part of the geometry pipeline.
		There are many more aspects to both the Direct3D 9 and 10 uses for vertex buffers, the majority of these were dropped so as to keep this article short and to the point.

	Direct3D 8 Tutorial #1
		With Direct3D, you can create a program that allows the operator to dynamically adjust his position with respect to a 3D object, to zoom in and out, and to rotate the object about its central axis.
		I decided to employ Direct3D 8, which is the version that ships as part of the Windows XP operating system.
		My goal was to use Direct3D to display 20 radial slices through the Munsell color solid and to allow the operator to select an arbitrary rotation, tilt, and zoom factor from which to view this representation of the color solid.

		Direct3D is only available for Microsoft's various Windows operating systems (Windows 95 and above) and is the base for the graphics API on the Xbox and Xbox 360 console systems.
		Direct3D is used to render three dimensional graphics in applications where performance is important, such as games.
		Direct3D 10 will forego the current DirectX practice of using "capability bits" to indicate which features are active on the current hardware.

	[No title]
		Direct3D, a major component of the DirectX Graphics subsystem, has evolved so rapidly in the last few years that the underlying programming paradigm has changed quite a bit from its origin.
		The Direct3D pipeline should be viewed as a set of algorithms that operate on 3D geometric quantities, which in the case of Direct3D are predefined vertices and primitives.
		The Direct3D tessellation stage is used to tessellate (convert to triangles) a fixed set of higher-order primitives that Direct3D predefines, which include triangle patches, rectangle patches, and N patches (although triangle patches remain the most common form of geometry).

	What is Direct3D? 3D Graphics DirectX Multimedia Gaming Game (Site not responding. Last check: )
		Direct3D is a type of API called a hardware abstraction layer that stands between the application and the hardware that will display it.
		Direct3D is the subset of DirectX that controls the drawing of 3D graphics.
		When you use Direct3D to draw your 3D graphics, you don't have to worry about what type of video card it's going to be drawn on, you don't have to worry about any limitations of the video card; Direct3D seperates you from the hardware.

	Direct3D FAQ
		The Direct3D debug runtime clears the back buffer alternately green or purple so if you see these colours you must not be clearing it yourself.
		There are two ways you can achieve this with Direct3D, the first is to render the second view to a texture and then render that texture onto a quad on the screen.
		Direct3D has a function SetViewport that allows you to specify just a part of the screen to render to.

	Dr. Dobb's \| Scientific Visualization with Direct3D 8.0 \| June 13, 2002
		I have chosen isovalues to produce intersecting surfaces; I make the four blobs opaque blue in color and the ellipsoid translucent gray so that the portions of the blobs that are inside the ellipsoid show through the ellipsoid (Figure 1).
		Direct3D uses the direction of normal vectors to determine the vertex’s orientation with respect to the incident light and the viewer when computing the color for each pixel in a triangle.
		In this application, the direction of a vertex’s normal vector is given by the gradient of the isosurface at the vertex.

		While Direct3D is based on Microsoft's COM, while OpenGL is based on pure C, based on a finite state machine model.
		Direct3D is therefore rather clumsy to use at times, although this may be put on the fact that it has a different purpose than OpenGL.
		Direct3D is rather a hardware interface, while OpenGL is, first of all, a rendering library, which may or may not be hardware accelerated.

		Direct3D is more like OpenGL in that it provides drawing primitives, but not such basic objects as spheres, cylinders, or cones, as QD3D does.
		Direct3D has been a long time coming, but it stands to exorcise all the hardware headaches that plague both 3-D programmers and game designers.
		Direct3D should boast such impressive features as a high degree of hardware abstraction, and its animation features will be of use to game and multimedia programmers.

	Direct3D Matrices
		Direct3D requires 3 matrices to be set before 3D geometry can be rendered.
		Direct3D uses a left handed system where X is right, Y up and Z in to the screen while OpenGL has X right, Y up and Z out of the screen.
		There are three matrix used by Direct3D to transform your 3D models into the final 2D image you see on the screen.

	Eep² - Active Worlds Help: Direct3D Support
		A RW Direct3D driver for AW is available, which provides better rendering performance and visual effects by using Direct3D and your 3D video card (depending on the card and if it even supports Direct3D—most do these days).
		If you think your video card meets these requirements, and you would like to try the RW Direct3D driver with AW on your computer, first be sure you have DirectX installed, then download the RW Direct3D driver.
		Keep in mind that just because a video card claims to support Direct3D, this does not necessarily mean that it provides the hardware acceleration features which RW requires to take full advantage of Direct3D.

	Taking Screenshots with Direct3D 8
		In earlier versions of DirectX, one could use the GDI to easily convert the output of a Direct3D application to a device-independent bitmap, which could then be saved to a BMP file.
		In Direct3D 8, it is no longer possible to retrieve a GDI device context for the front or back buffer surfaces.
		In fact, Direct3D applications are usually not given any access to the front and back buffer surfaces--by default, the back buffer is not lockable and there is no way to retrieve a pointer to the front buffer interface.

		Although Direct3D matrices are not standard objects-they are not represented by a COM interface-you can create and set them just as you would any other Direct3D object.
		Direct3D implementation assumes that the last column of this matrix is (0, 0, 0, 1).

	Microsoft and 3D Graphics
		It began to appear that Microsoft was using Direct3D to achieve market control and to limit innovation to areas that could not be used to challenge Microsoft, rather than to provide a technically superior product for its customers or to promote free competition between APIs.
		Nevertheless, Direct3D is much more capable than it was a year ago, and its evolution is beginning to diverge from that of OpenGL.
		Direct3D IM is the API that is currently most compatible with what we expect Fahrenheit LL to look like.

	Building Direct3D Programs
		There are four additional fg_ddsetup() flags used with Direct3D programs that control what type of 3D rendering a DirectX application will use, and if we will be using a Direct3D z-buffer.
		The third call uses Direct3D hardware acceleration if available, then checks for Direct3D software rendering, and finally defaults to Fastgraph's 3D rendering if Direct3D is not available.
		Fastgraph will only use Direct3D when drawing to the primary surface's back buffer (the back buffer is created in fg_vbinit() and uses virtual buffer handle 0).
