Hello I downloaded files and run on xampp localhost server. Images show up as blackscreen on slider, what should I do? I tried it on hostinger too - hpanel, same thing.

Would it be possible to adjust the vertex/fragment shaders of a demo, let's say demo5, so that they may work with a 2D framework like curtainsjs? I'm quite new to WebGL, so I attempted this and I've only gotten so far:

vertex shader:

precision mediump float;

attribute vec3 aVertexPosition;

uniform mat4 uModelViewMatrix;
uniform mat4 uProjectionMatrix;

varying vec2 vTextureCoord;

void main() {
  vTextureCoord = uv; // getting an error here saying uv is an undeclared identifier, is this a threejs variable?
  gl_Position = uProjectionMatrix * uModelViewMatrix * vec4(aVertexPosition, 1.0);
}

In the fragment shader there is a declaration: uniform vec4 resolution; is this using the default value: new THREE.Vector4()? I think curtainsjs only has Vec2 and Vec3 vector classes, will this be a problem? curtainsjs does have a Quaternion class though, do you think it's interchangeable with THREE.Vector4()?

Dear @akella thanks so much for your amazing development.
I am trying to implement it to use 23 images as a background. Trying from html adding instances it works till 7 images but then it stuck if the array has 8 img like in the following line:

I have download the zip file and browse to my all browser. it's shown no image on background each demo.

can you help me to solve it?

I love what you've been doing here, thank you for making it public!

I'm wondering if there's a way to modify the code so the images keep their own aspect ratio while covering the screen either horizontally or vertically, depending on their ratio, but never cropping the image? Especially interested in doing that with Demo 5.
