Hello @peskythisdot,

> Hi. I am translating a sketch from P5.java to P5.js. In java, it runs nice and smooth at a frameRate near 60. In p5.js the frameRate drops to around 4 f/s and a lot of details are missing. How can I improve this, or is WEBGL really that bad? Thanks. Edit: Please skip to the actual sketch I am translating [here below](https://discourse.processing.org/t/sketch-runs-slow-in-p5-js/31990/5). P5.java: int num; float pt[]; int style[]; float sin\_ar[]; float cos\_ar[]; float PRECISION = 1.0; int AR\_LENGTH = 360; void setup() { size(600, 600, P3D); background(255)…
