Microsoft strives to continually update Direct3D to support the latest technology available on 3D graphics cards. Integration with other DirectX technologies enables Direct3D to deliver such features as video mapping, hardware 3D rendering in 2D overlay planes, and even sprites, providing the use of 2D and 3D graphics in interactive media ties.ĭirect3D contains many commands for 3D computer graphics rendering however, since version 8, Direct3D has superseded the DirectDraw framework and also taken responsibility for the rendering of 2D graphics. Direct3D exposes the advanced graphics capabilities of 3D graphics hardware, including Z-buffering, W-buffering, stencil buffering, spatial anti-aliasing, alpha blending, color blending, mipmapping, texture blending, clipping, culling, atmospheric effects, perspective-correct texture mapping, programmable HLSL shaders and effects. Direct3D uses hardware acceleration if it is available on the graphics card, allowing for hardware acceleration of the entire 3D rendering pipeline or even only partial acceleration. Part of DirectX, Direct3D is used to render three-dimensional graphics in applications where performance is important, such as games. com /en-us /library /windows /desktop /hh309466ĭirect3D is a graphics application programming interface (API) for Microsoft Windows.
