is this always accurate though even if the normals change? i dont know much about normals.
But if the vertex positions are changed dynamically does this effect the normals' values?
or can i updatenormals() and will this recalculate the values so the returned slope is accurate

or am i simply blowing wind? as i say im not really up on normals
