If say func is GL_NEVER, the stencil test will always fail. Neither Color/Z-buffers are modified. The stencil buffer is modified as per glStencilOp fail. If say glStencilOp(GL_REPLACE, GL_KEEP, GL_KEEP) then GL_REPLACE takes place and stencilValue = (ref & stencilMask) // will become ref 2. Stencil Test Function passes/Depth Test Function fails:
Graphics represented as a rectangular grid of pixels. Rasterization Converting vector graphics to raster graphics. This terms also denotes a common method of rendering 3D models in real time. Ray casting Rendering by casting non-recursive rays from the camera into the scene. 2D ray casting is a 2.5D rendering method. Ray marching
Iterative Stencil Loops (ISLs) or Stencil computations are a class of numerical data processing solution [1] which update array elements according to some fixed pattern, called a stencil. [2] They are most commonly found in computer simulations , e.g. for computational fluid dynamics in the context of scientific and engineering applications.
A key concept in PDF is that of the graphics state, which is a collection of graphical parameters that may be changed, saved, and restored by a page description. PDF has (as of version 2.0) 25 graphics state properties, of which some of the most important are: The current transformation matrix (CTM), which determines the coordinate system
stencil; alpha; window ID; As a scene is drawn, drawing primitives (the basic elements of graphics output, such as points, lines, circles, text etc. [1]) are rasterized into fragments which are textured and combined with the existing frame buffer. How a fragment is combined with the data already in the frame buffer depends on various settings.
Fragment processing is a term in computer graphics referring to a collection of operations applied to fragments generated by the rasterization operation in the rendering pipeline. During the rendering of computer graphics, the rasterization step takes a primitive , described by its vertex coordinates with associated color and texture ...
A stencil is a template used to draw or paint identical letters, symbols, shapes, or patterns every time it is used. The design produced by such a template is also called a stencil. It may also refer to: Stencil buffer, used in 3D computer graphics; Stencil code, a class of algorithms; Stencil graffiti, stencils used in street art
In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation.
