Figure 7. The importance of the third-dimension

A: When viewed from the front (directly along the polar axis), the complete anterior Y suture pattern is seen to advantage but the posterior suture pattern is not visible. B: When rotated 90° about the equatorial plane, the opposite end curvature of fibers that results in anterior and posterior suture branches becoming offset is at least partially revealed. C: When rotated an additional 90° about the equatorial plane, the complete posterior suture pattern is seen to advantage but the offset anterior suture pattern is not visible. D: However, if the inner and outer broad faces of fiber groups in these CAD representations are depicted in different hues, and the anterior portion of fibers is rendered semitransparent, then the posterior portion of fibers can be viewed through the anterior portion of fibers when considered along the polar axis from the front. In the remaining CADs presented in this report, the inner and outer broad faces of opposite end curvature fibers are depicted in blue and green, while the inner and outer broad faces of straight fibers are rendered in red and yellow.
