Please consider using http://lygia.xyz instead of copy/pasting this functions. It expand suport for voronoi, voronoise, fbm, noise, worley, noise, derivatives and much more, through simple file dependencies. Take a look to https://github.com/patriciogonzalezvivo/lygia/tree/main/generative

Generic 1,2,3 Noise

float rand(float n){return fract(sin(n) * 43758.5453123);}

float noise(float p){
	float fl = floor(p);
  float fc = fract(p);

Encoding Video

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

I added a few methods to three-orbit-controls to be able to manually define phi or theta and be able to rotate to a given point.

// rotation in Y
controls.setAzimuthalAngle(theta);

// rotation in X
controls.setPolarAngle(phi);

Embed VTT subtitles into HTML

Objective

I have a video file on my local disk. I also have some subtitles (in HTML5's [WebVTT][] format).

I want to create an HTML file to play that video with subtitles, all from the local filesystem.

	$base-font-size: 16px;
	$base-line-height: 1.5;

	// this value may vary for each font
	// unitless value relative to 1em
	$cap-height: 0.68;


	@mixin baseline($font-size, $scale: 2) {

	#!/bin/bash

	fn="$1"
	of=${fn%.*}.jpg

	lf=`ffprobe -show_streams "$fn" 2> /dev/null \| awk -F= '/^nb_frames/ { print $2-1 }'`
	rm -f "$of"
	ffmpeg -i "$fn" -vf "select='eq(n,$lf)'" -vframes 1 "$of" 2> /dev/null
