public class IndexedLineArray
extends IndexedVertexGeometry

An OpenGL LineArray.

Lines cannot be picked in the traditional manner using geometry-based picking. The only way to pick them is based on their bounds.

Setting geometry

Part of the optimisation we make is to only copy into the underlying structures the exact number of coordinates, normals etc that are needed. To know this number, we need to know how many coordinates exist before attempting to set anything else. When constructing, or updating, geometry, you should always make sure that you first set the vertex list, then the sizing information for the strip or fan counts, and then set normals as needed.
