Are there any good examples of a scene using a texture3D, I saw the one MRI example but cant find the code for something similar.

We use it for colorgrading for instance:

github.com

BabylonJS/Babylon.js/blob/f3b4098c0f3f00f7f3993494bf833af266160b1b/src/Materials/Textures/colorGradingTexture.ts#L93


/**

 * Occurs when the file being loaded is a .3dl LUT file.

 */

private load3dlTexture() {

    var engine = this._engine;

    var texture: InternalTexture;

    if (engine.webGLVersion === 1) {

        texture = engine.createRawTexture(null, 1, 1, Constants.TEXTUREFORMAT_RGBA, false, false, Constants.TEXTURE_BILINEAR_SAMPLINGMODE);

    }

    else {

        texture = engine.createRawTexture3D(null, 1, 1, 1, Constants.TEXTUREFORMAT_RGBA, false, false, Constants.TEXTURE_BILINEAR_SAMPLINGMODE);

    }



    this._texture = texture;



    var callback = (text: string | ArrayBuffer) => {



        if (typeof text !== "string") {

            return;

        }
