I'm in the process of building a community for celebrating code-based art:

http://www.artywidget.com/
http://www.artywidget.com/about/

… and I'd love to include The Polygon Shredder. The focus for that site is passive art; think of a TV or photo frame on the wall where there may not even be an option for interaction. For that reason, I'd love to be able to programmatically hit the "close controls" and "close this message" buttons (e.g. with a URL parameter) so the audience can kick back and enjoy the art without extra visual distraction. Would that be okay with you? I'm happy to make a patch to this effect, but I wanted to check with you first.

Hi, Jaume!

Why do you have particle position multiplied by 18?

var positionsLength = curlNoiseModel.width * curlNoiseModel.height * 3 * 18;
var positions = new Float32Array( positionsLength );

var p = 0;

for( var j = 0; j < positionsLength; j += 3 ) {

    positions[ j ] = p
    positions[ j + 1 ] = Math.floor( p / 18 )
    positions[ j + 2 ] = p % 18
    p++;

}

geometry.addAttribute( 'position', new THREE.BufferAttribute( positions, 3 ) );

And can you give me a hint how to downshift particles shader for simple flat 2D sprite, like https://bl.ocks.org/vkuchinov/0942e561a993ce91d789299b44adfee0?

On Firefox Developer Edition with HTC Vive: https://www.clicktorelease.com/code/polygon-shredder/vr/

On desktop mirror, it tracks the headset pose, but the screen and headset are black after clicking Enter VR.

I would like to use the CurlNoise function and was wondering who's the author (to mention her/him). Is that you @spite or someone else? I'm talking about this one:

vec3 curlNoise( vec3 p ){
	const float e = .1;
	vec3 dx = vec3( e   , 0.0 , 0.0 );
	vec3 dy = vec3( 0.0 , e   , 0.0 );
	vec3 dz = vec3( 0.0 , 0.0 , e   );
	vec3 p_x0 = snoiseVec3( p - dx );
	vec3 p_x1 = snoiseVec3( p + dx );
	vec3 p_y0 = snoiseVec3( p - dy );
	vec3 p_y1 = snoiseVec3( p + dy );
	vec3 p_z0 = snoiseVec3( p - dz );
	vec3 p_z1 = snoiseVec3( p + dz );
	float x = p_y1.z - p_y0.z - p_z1.y + p_z0.y;
	float y = p_z1.x - p_z0.x - p_x1.z + p_x0.z;
	float z = p_x1.y - p_x0.y - p_y1.x + p_y0.x;
	const float divisor = 1.0 / ( 2.0 * e );
	return normalize( vec3( x , y , z ) * divisor );
}

By the way I also noticed that 2 other curl noise and 1 noise functions are not even used! You could remove ~100 lines. Amazing how short and clean is the code, compared to the complexity of the result. Bravo :)

Once we close the "Close this message" tab , then there is no way to open unless refreshing the page.
It is a quality problem I guess.

With all scale tunables ramped up my Nexus 5x is perfectly smooth, renders perfectly and barely gets warm (1,920 x 1,080), but my Ubuntu 17.04 Skull canyon gets a low framerate with rendering artifacts on the cube faces and blasts out a lot of hot air:

• Intel® Core™ i7-6770HQ CPU @ 2.60GHz × 8
• Intel® Iris Pro Graphics 580 (Skylake GT4e)
• 64 bit Ubuntu 17.04
• Google Chrome Version 63.0.3239.84 (Official Build) (64-bit)
• also 1920 x 1080

On the desktop, the github version has no facet artifacts but it's all dark and those parts have no artifacts on the web version. It still has a low framerate and throws out hot air.

Hey. First of all, this is an amazing project and has given me a lot of knowledge regarding three.js.

Wrt the issue, I was wondering the lights are a bit off compared to the online version. Is there something that I am missing here?
