Is there any equivalent to a OpenGL "provoking vertex"?

Hi,

Apologies in advance if this has been answered elsewhere.

I am looking into implementing flat shading in a project of mine and have come across a few methods to do so. One that piqued my interest was utilizing a method which included clever usage of the provoking vertex and the flat keyword in the glsl code.

Is this currently possible in wpgu?

Yup, this will work as expected in wgpu just as it would in OpenGL!

Thanks for the verification! I left out a flat qualifier on my fragment shader input, so I was running into odd behavior.
