Render arbitrary Polygons in DirectX11

is there a way to render arbitrary polygons with n > 3 corners in directx 11?

i remember this being possible in older OpenGL versions with GL_POLYGON but i haven found anything in the directX API for this.

The answer is not natively, there is no NGons primitive types, and the GL ones were mostly full of issues and quite near of a FAN.

You will have to triangulate yourself, it can be done with a geometry shader, receiving the control points and outputing the triangles

A compute shader with a DrawIndirect is possible and more versatile but need more setup to work.
