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.
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.
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 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.
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.
Simple and Fast Multimedia Library (SFML) is a cross-platform software development library designed to provide a simple application programming interface (API) to various multimedia components in computers.
The Lightweight Java Game Library (LWJGL) is an open-source software library that provides bindings to a variety of C libraries for video game developers to Java.It exposes cross-platform libraries commonly used in developing video games and multimedia titles, such as Vulkan, OpenGL, OpenAL and OpenCL.
An illustration of texture filtering methods showing a texture with trilinear mipmapping (left) and anisotropic texture filtering. In 3D computer graphics, anisotropic filtering (abbreviated AF) [1] [2] is a method of enhancing the image quality of textures.
