Parameters

light_data	A struct containing information about the light that is creating the shadows.
accumulated_fwd	The accumulated forward matrix.
render_caps	determines if one should draw end caps to the volume or if it is ok to leave it open.
coord	contains the coords.

Implements H3D::H3DShadowObjectNode.

virtual

Override to do implement shadows using a geometry shader.

Parameters

light_data	A struct containing information about the light that is creating the shadows.
