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. There are more than 52 thousand public contributions as of mid-2021 coming from thousands of users.
As powerful GPU hardware became more widely available, this method was popularized by the demoscene and Inigo Quilez, [citation needed] co-creator of Shadertoy. For simple scenes with basic 3D shapes, ray marching does not have many benefits over ray tracing (which finds intersections without marching through the space).
Video games outsource rendering calculations to the GPU over OpenGL in real-time. Shaders are written in OpenGL Shading Language and compiled. The compiled programs are executed on the GPU.
In imaging science, difference of Gaussians (DoG) is a feature enhancement algorithm that involves the subtraction of one Gaussian blurred version of an original image from another, less blurred version of the original.
The Blinn–Phong reflection model, also called the modified Phong reflection model, is a modification developed by Jim Blinn to the Phong reflection model. [1]Blinn–Phong is a shading model used in OpenGL and Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixel values between vertices are ...
A traditional snickerdoodle recipe includes unsalted butter, granulated sugar, eggs, all-purpose flour, cream of tartar, baking soda and salt.
However, some file signatures can be recognizable when interpreted as text. The column ISO 8859-1 shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise.
