A plot of the smoothstep(x) and smootherstep(x) functions, using 0 as the left edge and 1 as the right edgeSmoothstep is a family of sigmoid-like interpolation and clamping functions commonly used in computer graphics, [1] [2] video game engines, [3] and machine learning.
Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...
Modern video game development platforms such as Unity, Unreal Engine and Godot increasingly include node-based editors that can create shaders without the need for actual code; the user is instead presented with a directed graph of connected nodes that allow users to direct various textures, maps, and mathematical functions into output values ...
Shader nodes in Blender. Node graph architecture is a software design structured around the notion of a node graph. Both the source code and the user interface are designed around the editing and composition (or linking) of atomic functional units. Node graphs are a type of visual programming language.
The final step is interpolation between the 2 n dot products. Interpolation is performed using a function that has zero first derivative (and possibly also second derivative) at the 2 n grid nodes. Therefore, at points close to the grid nodes, the output will approximate the dot product of the gradient vector of the node and the offset vector ...
Flood-fill (node): 1. Set Q to the empty queue or stack. 2. Add node to the end of Q. 3. While Q is not empty: 4. Set n equal to the first element of Q. 5. Remove first element from Q. 6. If n is Inside: Set the n Add the node to the west of n to the end of Q. Add the node to the east of n to the end of Q. Add the node to the north of n to the ...
The API exposes seven programmable entry points within the ray tracing pipeline, allowing for custom cameras, ray-primitive intersections, shaders, shadowing, etc. This flexibility enables bidirectional path tracing, Metropolis light transport, and many other rendering algorithms that cannot be implemented with tail recursion.

There has been an emergence of 2D and 3D game engines for WebGL, [56] such as Unreal Engine 4 and Unity. [57] The Stage3D/Flash-based Away3D high-level library also has a port to WebGL via TypeScript. [25] [58] A more light-weight utility library that provides just the vector and matrix math utilities for shaders is sylvester.js.
