  • Figure 6.1. colorPerVertex="true" and colorPerVertex="false" effects for IndexedFaceSet and IndexedLineSet.

  • Figure 6.2. Convex and concave shapes.

  • Figure 6.3. Example use of the Color node to provide colorPerVertex="true" to the pump house in the Kelp Forest world.

  • Figure 6.4. Example use of PointSet node highlight the waypoints of the shark’s path. The points have been increased in size to better illustrate them.

  • Figure 6.5. Shark waypoints connected as an IndexedLineSet show the path travelled.

  • Figure 6.6. Shark waypoints connected with a LineSet show the path travelled. The lines have been made thicker to better illustrate them.

  • Figure 6.7. The pump house is built using IndexedFaceSet. The rocker arm and piston are built using X3D primitives.

  • Figure 6.8. Indexing scheme for the ElevationGrid height array.

  • Figure 6.9. Alternate forms of tesselation are possible for nonplanar ElevationGrid quadrilaterals.

  • Figure 6.10. Points making up a spine define a local Spine-aligned Cross-section Plane (SCP) where cross-sections are repeated.

  • Figure 6.11. Example pentagon extrusion views showing default rendering on left and SCP on right.

  • Figure 6.12. Extrusion example constructing the walls of a building.

  • Figure 6.13. Extrusion example constructing the hull, superstructure, and smoke trail of a ship.
