Rapper’s Delight Word Cloud

Prepared by Nick Shelton [email protected] for Rap Research Lab LLC 1/15/20

Rendering 5000 TextMeshPro meshes in 1ms for an interactive VR word cloud

I started with a naive 5000 TextMeshPro gameobjects, which could take 30ms CPU and GPU, and made a new system that took 1ms CPU and GPU and still looked dope.

I get a lot of requests for resources about how I learned about raymarching fractals or general computer graphics stuff. So I started this handy guide where I will add links and info about where I learned some things.

This is a non-exhaustive list I will probably add more in the future.

Reference

It used to be that you had to dig through FractalForums or pouet.net to find little nuggets of new techniques or ideas. But many smart people that have been doing much longer than I have condensed this knowledge into some articles. Here are a few that have helped me out on my journey.

Mercury Demogroup

Mercury.sexy demogroup has created a distance field library with some cool stuff in there. Except they said that fractals are boring.

	# download https://www.bodc.ac.uk/data/open_download/gebco/gebco_2020/geotiff/ and put into ./gebco/ folder
	# fyi rasterio only supports up to python 2.7

	import rasterio
	import matplotlib.pyplot as plt
	import math
	import glob
	import numpy as np
	import datetime
	import cv2

	using UnityEditor;
	using UnityEngine;
	using System.Collections.Generic;
	using UnityEngine.Tilemaps;
	using UnityEngine.Timeline;
	using UnityEngine.UI;
	using UnityEngine.U2D;
	using UnityEngine.Rendering;
	using UnityEngine.Playables;
	using UnityEngine.EventSystems;

	import numpy as np
	from sklearn.manifold import TSNE
	import glob
	import os
	import sys
	from numpy import genfromtxt
	import matplotlib.pyplot as plt

	numFilesRead = 0
	data = np.zeros((144,1))

	using System.Collections;
	using System.Collections.Generic;
	using UnityEngine;
	using UnityEditor;
	using System.IO;

	public class DiffusionLimitedAggregation : MonoBehaviour
	{
	[SerializeField]
	private int m_numPoints = 10000;

	I am attesting that this GitHub handle nshelton is linked to the Tezos account tz1dzRwpVJ9Muod4Srge22Fa599mzHSDHtrK for tzprofiles
