X_ITE X3D Player   Half-cylinder crease-angle demo illustrates how the crease angle value affects the smoothness of shading on a half-cylinder. The left half-cylinder has a crease angle of 0.0, causing faceted shading. The right half-cylinder has a crease angle of 1.571 (90 degrees), causing smooth shading. Both half-cylinders have *exactly* the same number of coordinates and faces, but the smooth shaded one looks better!
