Use a Pixi.js texture in Babylon

Hello all, I’m new to BabylonJS but an old hand at Pixi.

I’ve an asset management system running in Pixi and I was wondering if there’s any way to use a pre-loaded Pixi texture (which is pulled from a sprite sheet/atlas) and map it onto a plane in BabylonJS?

Thanks in advance!

hi welcome to forum please share any more detail
:slight_smile: you can use PG https://www.babylonjs-playground.com for add you PIXI texture and show us the issue

Am I missing something? That PG link doesn’t offer any help to my question…

You should add a playground so we could take a look at your code.

The thing is I have no code to post, I was just wondering if using a Pixi texture was possible.

Basically I was wondering if I can covert a PIXI.Texture into a BabylonJS texture for use on a material.

basically you can use any canvas picture to any other canvas render engine
just search dynamic material or get canvas texture

Hey @digitaloranges, I spent some time trying to get pixi to render to a DynamicTexture in this PG:

Unfortunately, I can’t quite figure out what’s going on with the ordering of the objects in scene, but it seems possible.
@Deltakosh, got any idea why the sphere is getting clipped by the ground mesh?

Can you post code to show what that is?

Reason being… there is probably a way.

Looking at the BABYLON Sprite Texture Packer… it is just a png (for example).

https://doc.babylonjs.com/babylon101/sprites

So, a minimum way to make it work would be to implement one of those PG’s on that page.

Reusing the png.

One way to dig deeper into BJS awesomeness is:

https://doc.babylonjs.com/api/classes/babylon.spritepackedmanager

Probably I’m on a tangent (as usual).

But I see… SpriteJSON and URL. Never used it… someday maybe.

Deeper still… you can SEARCH PLAYGROUND (PG)

https://doc.babylonjs.com/playground/

GREAT Sprite examples there.

And read source code.

Welcome to the forum.

The PG is not workin and @sebavan is now our Pixi expert :smiley:

Pressing the play button gets the scene to load if it initially fails

You are rendering pixi in the main canvas and not to a texture. A dynamic texture wraps a canvas but usually a different one than the babylon one so either you need to make pixi render to a renderTarget or you need to use it on a separate canvas wrapped into a dynamicTexture.

Found ONE example of PIXI rendering in PG:

https://www.babylonjs-playground.com/#1QJHY3#10

You could use it to fix the ‘PIXI is not defined’ error here…

I think this could be really powerful.

I’ve worked out how to to do using a DynamicMaterial.

I’ve developed a framework in Pixi that handles the loading of assets (textures etc) and wanted to use this asset manager in my Babylon project. I also wanted to use the TexturePacker facility using sheets/atlases.

Firstly, to create a Babylon texture from a Pixi texture, I create a new DynamicMaterial then draw the Pixi source image into it:

 function convertPixiTexture(baseTexture: FW.BaseTexture, width: number, height: number, mipMaps = false): BABYLON.BaseTexture
    {
        // Create Babylon texture
        const texture: BABYLON.DynamicTexture = new BABYLON.DynamicTexture("pixi-texture-" + name,
            {
                width: width,
                height: height
            }, mainScene, mipMaps);
        texture.hasAlpha = true;
        const textureContext: CanvasRenderingContext2D = texture.getContext();

        // Draw PIXI texture to new texture
        textureContext.drawImage(baseTexture.source, 0, 0, width, height, 0, 0, width, height);
        texture.update();

        return texture;
    }

Then I use the TexturePacker frame rectangle info to map that texture onto a plane.

Hi @digitaloranges !
Let see my example in this post, i think them useful for you.
