X3D Example Archives: X3D for Web Authors, Chapter 13 Geometry Triangles Quadrilaterals

Triangles and quadrilaterals are fundamental geometry representations that are typically created by authoring tools to build complex polygonal meshes and shapes.

Low-level high-performance nodes for geometry definition and fast rendering include TriangleSet, TriangleFanSet, TriangleStripSet, IndexedTriangleSet, IndexedTriangleFanSet, IndexedTriangleStripSet, QuadSet and IndexedQuadSet. Special definition rules apply to each node in order to best match underlying graphics hardware requirements. Each is placed individually inside a Shape node.

The supporting Chapter 13 slideset and course videos (NPS, YouTube) for X3D for Web Authors are available online via X3dGraphics.com.
