Hi all!

I’m using `AssetsManager` to load my assets and would like to use it for a terrain heightmap as well.  
`MeshBuilder.CreateGroundFromHeightMap` taking an already loaded image instead an URL-string as a parameter would be helpful for that.

Regards,

. J

… or even a `Uint8Array` as `VertexData.CreateGroundFromHeightMap` does, so that `AssetsManager` can prepare as much as possible upfront.

+1 from my side, would be great having this possibility!

The url can be constructed from a blob if you want to:

```auto
            var blob = new Blob([data], { type: "octet/stream" });
            var url = URL.createObjectURL(blob

```

Then you can use that url with the MeshBuilder

Yes. I agree, this request is more for convenience than essential.

But this is more of a workaround? My goal was making terrain creation quick by using a preloaded image.  
Loading image, creating a potentially multimegabyte URI that has to get parsed again does not sound to be ‘quick’.

What already helps today is preloading the image in `AssetsManager`. `MeshBuilder.CreateGroundFromHeightMap` then will not load it again from the web. Babylon or the browser seems to cache…

Yes and this is why I see not a real need as you can simply reload it and trust the browser cache (which will be really fast )
