question: public void copyTo ( PositionTextureVertex [ ] verts , TexturedQuad [ ] quad ) { TexturedPolygon [ ] poly = new TexturedPolygon [ quad . length ] ; for ( int idx = 0 ; idx < quad . length ; idx ++ ) { poly [ idx ] = new TexturedPolygon ( ( PositionTextureVertex [ ] ) quad [ idx ] . vertexPositions ) ; } copyTo ( verts , poly ) ; }
target:  Copies an array of vertices and quads to the current shape. This method converts quads to polygons and then calls the main copyTo method.
