DirectWrite is a text layout and glyph rendering API by Microsoft.It was designed to replace GDI/GDI+ and Uniscribe for screen-oriented rendering and was first shipped with Windows 7 and Windows Server 2008 R2, as well as Windows Vista and Windows Server 2008 (with Platform Update installed). [1]
Immediate mode is an API design pattern in computer graphics libraries, in which . the client calls directly cause rendering of graphics objects to the display, or in which; the data to describe rendering primitives is inserted frame by frame directly from the client into a command list (in the case of immediate mode primitive rendering),
Rendering APIs typically provide just enough functionality to abstract a graphics accelerator, focussing on rendering primitives, state management, command lists/command buffers; and as such differ from fully fledged 3D graphics libraries, 3D engines (which handle scene graphs, lights, animation, materials etc.), and GUI frameworks; Some provide fallback software rasterisers, which were ...
RenderScript is designed to always run on the various Android platforms regardless of hardware type. Performance tuning is done at runtime. RenderScript portability depends upon device-specific drivers: [4] a basic CPU-only driver is provided for every device, while there exist some specific chipset-provided RenderScript drivers that enable GPU usage (e.g. Qualcomm specific drivers, which are ...
When copy is set, each backbuffer is copied forward, but the screenbuffer is not wrapped to the last buffer, leaving it unchanged. Flip does not work when there is only one backbuffer, as the screenbuffer is copied over the only backbuffer before it can be presented. In discard mode, the driver selects the best method. [2]
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 ...
Retained mode in computer graphics is a major pattern of API design in graphics libraries, [1] in which the graphics library , instead of the client , retains the scene (complete object model of the rendering primitives ) to be rendered and
Tiled rendering is the process of subdividing a computer graphics image by a regular grid in optical space and rendering each section of the grid, or tile, separately. The advantage to this design is that the amount of memory and bandwidth is reduced compared to immediate mode rendering systems that draw the entire frame at once.
