getTessellatedVerticesForPatch method

Vertices getTessellatedVerticesForPatch({ required List<int> cornerIndices, required RenderedOMeshRect verticesMesh, required RenderedOMeshRect textureMesh, required int tessellation, })

Returns a Vertices object with the given cornerIndices, verticesMesh, textureMesh, and tessellation.
