A GPU is also a great tool for general-purpose computations. There are a few ways to couple it with Wolfram Language:

• CUDALink
• OpenCLLink
• LibraryLink

The first option requires hardware from Nvidia, which is a massive drawback considering there are many other processors on the market capable of crunching numbers. The last option allows integrating any dynamic library written in C/Rust (probably there are other bindings as well) into our Kernel, but the amount of effort required to write a general-purpose GPU library and deal with cross-platform issues is quite cumbersome and defeats the whole purpose of using WL here.

We will go with the most cross-platform and hardware-agnostic solution: OpenCL 🚅

Using Wolfram Language and WLJS

In this notebook we will apply some optimizations to the code, expand the resolution and switch to immediate mode of graphics rendering.

It is quite tricky to make an efficient function for plotting dynamic 3D surfaces, which change with time using a high-level code such as Wolfram Language.

This is going to be our first dev-log post here 🦄

MatrixPlot[
 Fourier[Table[
   UnitStep[i, 4 - i] UnitStep[j, 7 - j], {i, -25, 25}, {j, -25, 
    25}]]]

It means, MatrixPlot as well as Rasterize can work properly finally

There is nothing more exciting in programming than designing a graphics application. Thankfully, there is one person on Github Garrett Johnson, who implemented a path-tracing algorithm on top of the well-known THREE.js graphics engine. Moreover, it fully supports features from the original library and can be anytime flipped as a main renderer.
