nodiscard

Compare two meshes for equality.

Parameters

vertices	Vertices of the first mesh. Order doesn’t matter.
indices	Indices of the first mesh. Triangle order doesn’t matter. Vertex order in a triangle only matters for winding.
expected	The second mesh, in a quad form.

Returns

Whether the two meshes are equal.

Note

There are two ways to split a quad into 2 triangles; either is allowed.
