GPGPU birds example with GLTF loader and MeshStandardMaterial

[santi-grau]

• Extending the GPGPU birds demo so that it can load any GLTF model/animation and use MeshStandardMaterial to shade.
• GLTF vertices are baked onto a texture. One frame per row
• Texture is passed to the vertex shader along with a frame reference.
• MeshStandardMaterial is applied

Demo here :
https://uber-gpgpu-demo.glitch.me

• On demo, a new geo is loaded randomly, may be confusing...

This is my first PR ever. Not sure if this is even helpful or correctly done but would like to learn the process to contribute to three in the future.

When I reloaded and saw the flocking horses: 🤯 😍

This is really cool, great work.

This section would be nicer written as a template string. @Mugen87 do we allow these in examples yet?

[mrdoob]

Yes, I think we can use template strings in examples. They're using modules anyway.

@santi-grau can you change this to use template strings?

var insert = /* glsl */`
    attribute vec4 reference;
    attribute vec4 seeds;
    attribute vec3 birdColor;
    uniform sampler2D texturePosition;
    ...  
    `;

[santi-grau]

Sure! will look into all this during the weekend :)

[santi-grau]

Put all the 'replacement' strings into a template string. Hope this is what you meant. :S

[mrdoob]

Santiii! Mola!! 🤩

Live example using githack.

Thanks!

Okay, mrdoob just merged the commit without screenshot. Prepare to bugs in a repo.

[santi-grau]

Sorry guys, I'm really new to collaborating on github, I normally work on small stuff on my own. Is there anything I can do to help?

[munrocket]

We are new too, the problem that reviewers don’t care. That’s all :D

[mrdoob]

@santi-grau Don't worry! I'll take care of it 👌

[Mugen87]

@mrdoob I've added the screenshot with 0af67e4 so #19341 has a clean build.

@Mugen87 Thanks!
