Subsurface scattering is an indirect form of reflection where some of the light is transmitted into a semi-transparent material, scattered under the surface and bounced back out again.
Originally, this functionality was achieved by writing shaders in ARB assembly language – a complex and unintuitive task. The OpenGL ARB created the OpenGL Shading Language to provide a more intuitive method for programming the graphics processing unit while maintaining the open standards advantage that has driven OpenGL throughout its history.
A procedural image made in Shadertoy with distance fields, modeled, shaded, lit and rendered in realtime. Shadertoy is an online community and platform for computer graphics professionals, academics [1] and enthusiasts who share, learn and experiment with rendering techniques and procedural art through GLSL code.
This shader works by replacing all light areas of the image with white, and all dark areas with a brightly colored texture. In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as shading.
The unified shader model uses the same hardware resources for both vertex and fragment processing. In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as "Shader Model 4.0") refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities.
Metal is a low-level, low-overhead hardware-accelerated 3D graphic and compute shader API created by Apple, debuting in iOS 8. Metal combines functions similar to OpenGL and OpenCL in one API. It is intended to improve performance by offering low-level access to the GPU hardware for apps on iOS , iPadOS , macOS , and tvOS .
Dominant/complementary wavelength example on the CIE color space The "x" marks the color in question. For the white point indicated, the dominant wavelength for "x" is on the nearer perimeter, around 600 nm, while the complementary wavelength is opposite, around 485 nm. Intuitively, the dominant wavelength of "x" corresponds to the primary hue ...
Star Wars: SC 38 – Reimagined is a 2019 fan remake of the 38th scene in Star Wars (1977), in which the characters of Obi-Wan "Ben" Kenobi and Darth Vader engage in a lightsaber duel on the first Death Star. It was directed by Philip Silvera, and stars stuntmen Dan Brown and Richard Cetrone performing in the new footage as Kenobi and Vader ...
