public class VirtualIndexBuffer extends IndexBuffer
Mesh.Mode.
The generated indices are as if the mesh is in the given mode
but contains no index buffer, thus this implementation will
return the indices if the index buffer was there and contained sequential
triangles.
Example:
Mesh.Mode.Triangles: 0, 1, 2 | 3, 4, 5 | 6, 7, 8 | ...Mesh.Mode.TriangleStrip: 0, 1, 2 | 2, 1, 3 | 2, 3, 4 | ...Mesh.Mode.TriangleFan: 0, 1, 2 | 0, 2, 3 | 0, 3, 4 | ...| Modifier and Type | Field and Description |

IndexBufferPuts the vertex index at the index buffer's index.
Implementations may throw an UnsupportedOperationException
if modifying the IndexBuffer is not supported (e.g. virtual index
buffers).

Implementations may return null if there's no underlying

IndexBufferPuts the vertex index at the current position, then increments the
position. Implementations may throw an
UnsupportedOperationException if modifying the IndexBuffer is not
supported (e.g. virtual index buffers).

IndexBufferThis method can be used to set an IndexBuffer to a
Mesh:
mesh.setBuffer(Type.Index, 3,
indexBuffer.getFormat(), indexBuffer);
