Lines Matching full:vertex
169 // The case where one vertex lies on the thick-plane and the other
248 // vertex_before stores the index of the vertex before its matching
250 // i.e. vertex_before[0] stores the vertex we saw before we crossed the plane
280 // vertex set for both our new polygons.
319 // This algorithm takes the first vertex in the polygon and uses that as a
321 // |offset| starts off as the second vertex, and then |op1| and |op2| indicate
323 // After the first quad is created, the first vertex in the next quad is the
324 // same as all the rest, the pivot point. The second vertex in the next quad is
325 // the old |op2|, the last vertex added to the previous quad. This continues
328 // case we use the same values for vertex 3 and 4 to make a degenerate quad
