A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
OpenGL (Open Graphics Library) is a graphics standard and API which is platform-independent and available for desktop, workstation and mobile devices. It is designed to provide hardware-accelerated re…
Questions specific to raytracing (as opposed to scanline rendering), the 3D graphics technique of intersecting rays from the camera with objects in the scene.
Questions about the conversion of a 2D or 3D model to a photorealistic or non-photorealistic image.
Questions and problems dealing with three-dimensional space, including 3D meshes and other data structures, vector math, transformations, etc.
For all questions related to shaders, i.e. the programmable part of the GPU pipeline. For language-specific shader questions, see also the [glsl] and [hlsl] tags.
GLSL is the OpenGL shading language. Use this tag for questions which are specifically about shaders written in this language. For generic shader questions use [shader] instead.
For questions related to textures: procedural generation, encodings, aspect characterisation, filtering, mapping, storage...
Transformations are mathematical operations that can be applied to an object to change its scale, position and orientation.
For questions about the path tracing Monte Carlo algorithm for physically accurate global illumination, or its variants.
The knowledge of the numbers, formulas, shapes and quantities. In the computer graphics, almost exclusively linear algebra is being used.
General-purpose programming language used widely in game development and CPU-intensive tasks.
Problems involving meshes and other geometry representations, and manipulating, transforming, or extracting information from them; algorithms for solving geometrical problems such as computing interse…
Questions about the rigorous usage of instructions used to solve a specific computer graphics problem.
Questions about a network of connected vertices, edges and faces to describe the shape of a specific 3D object.
Questions related to the massively parallel computing units targeting effective computer graphics in modern machines.
Questions about the visual perceptual property deriving from the spectrum of light, usually expressed numerically according to a color model.
Questions about the conversions of a 3D model to a 2D model.
For questions about the Vulkan graphics/compute API.
WebGL extends the capability of the HTML canvas element to allow it to render accelerated 3D graphics in any compatible web browser.
HLSL is the High-Level Shading Language, used to author shaders for use with Direct3D, and cross-compilable to SPIR-V. Use this tag for questions which are specifically about shaders written in this l…
For questions related to the rasterization process, both in terms of GPU hardware and algorithms related to rasterization.
