Color Per Vertex Examples

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.

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.
ColorPerVertexExamples Color Per Vertex Examples Geometry Polygons Nodes: Color, Coordinate, IndexedFaceSet, IndexedLineSet, PointSet
ElevationGridNonPlanarQuadrilaterals Elevation Grid Non Planar Quadrilaterals Show how a single nonplanar quadrilateral can be tesselated in 2 different ways.
ExtrusionCrossSectionITSSPrototype Extrusion Cross Section ITSSPrototype Shape prototype for Enclosing IndexedTriangleStripSet that also draws spine line plus oriented, scaled cross sections at each spine point.
ExtrusionCrossSectionPrototype Extrusion Cross Section Prototype Shape prototype for Extrusion node that also draws spine line plus oriented, scaled cross sections at each spine point.

ExtrusionRoomWalls Extrusion Room Walls Wall definition for a room, defined as a cross section and extruded vertically.
IndexedFaceSetExample Indexed Face Set Example Positive-displacement cylinder pump house built using IndexedFaceSet nodes.
IndexedLineSetExample Indexed Line Set Example The way points and path of the animated shark Lucy traversing the tank, using IndexedLineSet node.
LineSetComparison 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.
LineSetExample Line Set Example The way points and path of the animated shark Lucy traversing the tank, using LineSet node.
PointSetExample Point Set Example Way points for the animated shark Lucy traversing the tank.
