DirectDraw also allows applications to run fullscreen or embedded in a window such as most other MS Windows applications. DirectDraw uses hardware acceleration if it is available on the client's computer. DirectDraw allows direct access to video memory, hardware overlays, hardware blitters, and page flipping.
The first version of DirectX was released in September 1995 as the Windows Game SDK. Its DirectDraw component was the Win32 replacement for the DCI [17] and WinG APIs for Windows 3.1. [18] DirectX allowed all versions of Microsoft Windows, starting with Windows 95, to incorporate high-performance multimedia.
The first version of Direct3D shipped in DirectX 2.0 (June 2, 1996) and DirectX 3.0 (September 26, 1996). Direct3D initially implemented an "immediate mode" 3D API and layered upon it a "retained mode" 3D API. [18] Both types of API were already offered with the second release of Reality Lab before Direct3D was released. [16]
The System tab displays the current DirectX version, the computer's hostname, the operating system's version, information on the system BIOS, and other data.The DirectX Files tab displays information about the versions of specific DirectX system files, which are portable executables or dynamic-link libraries (DLLs).
GDI was present in the initial release of Windows. MS-DOS programs had manipulated the graphics hardware using software interrupts (sometimes via the Video BIOS) and by manipulating video memory directly. Code written in this way expects that it is the only user of the video memory, which was not tenable on multi-tasked environment, such as ...
Another buffer is allocated in the video memory to represent the DirectX surface, which is used as the texture for the window meshes. The system memory buffer is converted to the DirectX surface separately and kept in sync. This round-about route is required because GDI cannot output directly in DirectX pixel format.
An updated version of Direct2D was launched with Windows 8 in October 2012. [8] It was also backported to Windows 7 SP1 (but not to Windows Vista) via the Windows 7 platform update . [ 9 ] [ 10 ] [ 11 ] The original version of Direct2D was tied to DirectX 11 (in hardware, up to Direct3D 10.1 is used), whereas this version of Direct2D integrates ...
WDDM drivers allow video memory to be virtualized, [6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back.
