Each context rasterizes the drawing at the desired resolution without altering the data that defines the drawing. Thus, contexts are the mechanism by which Quartz 2D employs resolution- and device-independence. For example, a window context may rasterize an object to the appropriate screen resolution to create actual graphics on the display.
In Apple's macOS operating system, Quartz is the Quartz 2D and Quartz Compositor part of the Core Graphics framework. Quartz includes both a 2D renderer in Core Graphics and the composition engine that sends instructions to the graphics card. Because of this vertical nature, Quartz is often synonymous with Core Graphics. [1]
The bitmap output from Quartz 2D, OpenGL, Core Image, QuickTime, or other process is written to a specific memory location, or backing store.The Compositor then reads the data from the backing stores and assembles each into one image for the display, writing that image to the frame buffer memory of the graphics card.
Example mechanical drawing. Here is an example of an engineering drawing (an isometric view of the same object is shown above). The different line types are colored for clarity. Black = object line and hatching; Red = hidden line; Blue = center line of piece or opening; Magenta = phantom line or cutting plane line
An example of Electron beam lithograph setup. Electron-beam lithography (often abbreviated as e-beam lithography or EBL) is the practice of scanning a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive film called a resist (exposing). [1]
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [ 1 ] It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three- dimensional exploded diagram.
In shallow drawing, the depth of drawing is less than the smallest dimension of the hole. Bar, tube, and wire drawing all work upon the same principle: the starting stock is drawn through a die to reduce its diameter and increase its length. Usually, the die is mounted on a draw bench. The starting end of the workpiece is narrowed or pointed to ...
Contour drawing is an essential technique in the field of art because it is a strong foundation for any drawing or painting; it can potentially modify a subjects’ form through variation within the lines. It is widely accepted among schools, art institutions, and colleges as an effective training aid and discipline [3] for beginner artists. In ...
