-- Relative Units for Offset and Length
|
|
-- This example shows an arrow pointing from one scene graph node in the direction of
|
|
-- another, but where the size is specified using relative values (based on the bounding
|
|
-- sphere of the start node). Here it points from Earth to the Moon.
|
|
--
|
|
-- Note that the arrows are generated as objects in 3D space and need to have a size
|
|
-- that is suitable for the scene graph nodes they refer to. Here it is set based on
|
|
-- the size of the start node, i.e. Earth.
