Class Vertex

Represents a vertex of a polygon. Use your own vertex class instead of this one to provide additional features like texture coordinates and vertex colors. Custom vertex classes need to provide a pos property and clone(), flip(), and interpolate() methods that behave analogous to the ones defined by Vertex. This class provides normal so convenience functions like CSG.sphere() can return a smooth vertex normal, but normal is not used anywhere else.

clone()
flip()

Invert all orientation-specific data (e.g. vertex normal). Called when the orientation of a polygon is flipped.

interpolate(other, t)

Create a new vertex between this vertex and other by linearly interpolating all properties using a parameter of t. Subclasses should override this to interpolate additional properties.
