A method for constructing mapping coordinates for a high-resolution graphics model includes the steps of expanding a projection cage to substantially encompass both a low-resolution graphics model and the high-resolution graphics model, and defining a volume that extends from a polygon of the projection cage through a corresponding polygon of the low-resolution graphics model. The method also includes the steps of determining points within an area on a surface of the high-resolution graphics model defined by an intersection of the volume and the high-resolution model, and, for each point where the corresponding polygon is the closest polygon of the low-resolution graphics model to the point, projecting the point to the corresponding polygon to define a projection point on the corresponding polygon.
