Hello Caroline and all Metal by Example authors,

Thanks for such a high quality tutorial on Metal! This is much needed for Apple CG community! : )

On the example, the terrain plane was created programatically on code.
I would like to apply the tessellation on an OBJ that I loaded into Xcode. How can I do that?

Best,
Alex

Warren Moore has done a teapot. The teapot is the original Utah teapot with Bezier control points:

Hello, Caroline , I just try this demo you show, but I can run it successfully.
