Make Mesh from Image (Alpha)

Hello,

Is it possible to create a mesh from an image from the alpha within Unity? I want to be able to do this at runtime. For example:

alt text

So the first image, is a standard image of a rocket within unity, and it has an alpha. Now I want to be able to create a mesh, as such, around the image. Does anyone know what this technique is called, and if there are already made systems out there that can do this?

Do to the nature of the app, it can't be a sprite, and it needs to be able to do it during runtime. I've got a plugin called UCLA MeshCreator, but it's only an editor plugin, and does not support runtime.

Thanks.

Thank you for this. Another note is that I'm don't want to work in a sprite system. Also, I need this to happen at run time. Thanks

Hey. Did you find the answer to your question? I have such a problem with you. But I need to get a mesh that will have holes. I found a triangulator for unity. But it does not work to process transparent places inside the picture. Npostite for my English
