New features were added to Direct2D with Windows 8.1 in October 2013: [13] Geometry realizations, [14] Direct2D effects API, [15] [16] [17] command list API, multithreading APIs, per-device rendering priority, support for JPEG YCbCr images for smaller memory footprint, and support for block compressed formats (DDS files).
It is available for Windows Vista and Windows Server 2008 through platform update for Windows Vista. WARP can be used when no compatible hardware is available, in kernel mode applications or in a headless environment, or for remote rendering of Direct2D/DirectWrite for Remote Desktop Connection clients.
Parallel rendering (or distributed rendering) is the application of parallel programming to the computational domain of computer graphics. Rendering graphics can require massive computational resources for complex scenes that arise in scientific visualization , medical visualization , CAD applications, and virtual reality .
Software rendering is the process of generating an image from a model by means of computer software. In the context of computer graphics rendering, software rendering refers to a rendering process that is not dependent upon graphics hardware ASICs, such as a graphics card. The rendering takes place entirely in the CPU. Rendering everything with ...
For 2D rendering, the DDX driver must also take into account the DRI clients using the same graphics device. the access to the video card or graphics adapter is regulated by a kernel component called the Direct Rendering Manager (DRM). [10] Both the X Server's DDX driver and each X client's DRI driver must use DRM to access the graphics hardware.
The draw call improvements of Mantle help alleviate cases where the CPU is the bottleneck. The design goals of Mantle are to allow games and applications to utilize the CPUs and GPUs more efficiently, eliminate CPU bottlenecks by reducing API validation overhead and allowing more effective scaling on multiple CPU cores, provide faster draw routines, and allow greater control over the graphics ...
The 3D pipeline usually refers to the most common form of computer 3-Dimensional rendering called 3D polygon rendering [citation needed], distinct from Raytracing and Raycasting. In Raycasting, a ray originates at the point where the camera resides, and if that ray hits a surface, the color and lighting of the point on the surface where the ray ...
A distinction is made between real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or animation), and offline rendering (sometimes called pre-rendering) in which images, or film or video frames, are generated for later viewing. Offline rendering can use a slower and ...
