The shader assembly language in Direct3D 8 and 9 is the main programming language for vertex and pixel shaders in Shader Model 1.0/1.1, 2.0, and 3.0. It is a direct representation of the intermediate shader bytecode which is passed to the graphics driver for execution.
GLSL shaders themselves are simply a set of strings that are passed to the hardware vendor's driver for compilation from within an application using the OpenGL API's entry points. Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string.
Another use of shaders is for special effects, even on 2D images, (e.g., a photo from a webcam). The unaltered, unshaded image is on the left, and the same image has a shader applied on the right. This shader works by replacing all light areas of the image with white, and all dark areas with a brightly colored texture.

Optical ray tracing describes a method for producing visual images constructed in 3-D computer graphics environments, with more photorealism than either ray casting or scanline rendering techniques. It works by tracing a path from an imaginary eye through each pixel in a virtual screen, and calculating the color of the object visible through it.
In the field of 3D computer graphics, deferred shading is a screen-space shading technique that is performed on a second rendering pass, after the vertex and pixel shaders are rendered. [2] It was first suggested by Michael Deering in 1988. [3] On the first pass of a deferred shader, only data that is required for shading computation is gathered.
Current generation gaming systems are able to render 3D graphics using floating-point frame buffers, in order to produce HDR images. To produce the bloom effect, the linear HDRR image in the frame buffer is convolved with a convolution kernel in a post-processing step, before converting to RGB space. The convolution step usually requires the ...
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 ...
