Numerous X3D nodes are available for presenting points, lines, and a variety of polygonal meshes. Many kinds of geometry can be created using PointSet, LineSet, IndexedLineSet, IndexedFaceSet, ElevationGrid and Extrusion nodes. Each is placed individually inside a Shape node. Geometric properties are controlled by Color, ColorRGBA, Coordinate, CoordinateDouble, Normal, TextureCoordinate, TextureCoordinateGenerator and MultiTextureCoordinate nodes. The supporting Chapter 6 slideset and course videos (NPS, YouTube) for X3D for Web Authors are available online via X3dGraphics.com. Also available: X3D Scene Authoring Hints: Meshes. |
| 15 X3D Models | X3D Model Descriptions | |
|---|---|---|
| Color Example | Vertex color applied to IndexedFaceSet built positive-displacement cylinder pump house. Note that this scene is not really static because the PositionInterpolators contain an initial offest of the piston and rocker arm. | |
|
Color Per Vertex Examples | Geometry Polygons Nodes: Color, Coordinate, IndexedFaceSet, IndexedLineSet, PointSet |
|
Elevation Grid Non Planar Quadrilaterals | Show how a single nonplanar quadrilateral can be tesselated in 2 different ways. |
|
Extrusion Cross Section ITSSPrototype | Shape prototype for Enclosing IndexedTriangleStripSet that also draws spine line plus oriented, scaled cross sections at each spine point. |
|
Extrusion Cross Section Prototype | Shape prototype for Extrusion node that also draws spine line plus oriented, scaled cross sections at each spine point. |
|
Extrusion Pentagon | Simple regular pentagon extruded vertically, shown side-by-side with an ExtrusionCrossSection visualization. |
|
Extrusion Pentagon Cross Section Itss | Comparison of Extrusion, ExtrusionCrossSectionPrototype, ExtrusionCrossSectionITSSPrototype. |
|
Extrusion Pentagon Cross Section Itss Texture | Comparison of Extrusion, ExtrusionCrossSectionPrototype, ExtrusionCrossSectionITSSPrototype for Texture Mapping. |
|
Extrusion Room Walls | Wall definition for a room, defined as a cross section and extruded vertically. |
|
Indexed Face Set Example | Positive-displacement cylinder pump house built using IndexedFaceSet nodes. |
|
Indexed Line Set Example | The way points and path of the animated shark Lucy traversing the tank, using IndexedLineSet node. |
|
Line Set Comparison | A simple wireframe cube, comparing two functionally equivalent nodes: IndexedLineSet (per-vertex coloring) with LineSet (per-segment coloring). Keeping track of how each node "connects the dots" is simply a book-keeping problem. |
|
Line Set Example | The way points and path of the animated shark Lucy traversing the tank, using LineSet node. |
|
Point Set Example | Way points for the animated shark Lucy traversing the tank. |
