Fast way to render lots of spheres
Setup:
1. Index buffer containing N quads (each 2 triangles), where N is the max amount of spheres. Repeating pattern of {0,1,2,1,3,2} + K*4.
2. No vertex buffer.
Render N*2 triangles, where N is the number of spheres you have.
Vertex shader:
1. Sphere index = N/4 (N = SV_VertexId)
2. Quad coord: Q = float2(N%2, (N%4)/2) * 2.0 - 1.0
3. Transform sphere center -> pos

Use WebWorkers and promises to run sync heavy functions in a worker (process) and get the result in a promise
function asyncThread(fn, ...args) {
if (!window.Worker) throw Promise.reject(
new ReferenceError(`WebWorkers aren't available.`)
);
const fnWorker = `
self.onmessage = function(message) {
(${fn.toString()})
.apply(null, message.data)
.then(result => self.postMessage(result));

A stupid C++ trick for defining structs with metadata (serializers, printers, etc) without redundant declarations of members
#include <iostream>
#include <vector>
#include <string>
using std::string;
/*
These macros define a struct with an implicitly defined Show function that visits each member.
The trick is that a typedef is split between each STRUCT_MEMBER instance and the preceding macro,
which allows it to define an empty struct type that identifies the following struct member, while also
knowing the struct type that the preceding macro is using to identify the current member.
