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.
