Hi Tony
Hi Sebastian,
In my case I am trying to simulate an illumination shell dropping from a
height and lighting the scene below for a given duration so I don't have a
model. Is it just a case of creating a node at the desired position and add a
lightsource to it as per the osglightsource example? The shell is a ball of
light. Can I specify the size of the light? And how do I make it self
illuminating?
If you don't need a modelled shell you simply need a group with a
osg::Lightsource and an associated osg::Light. A light is not
represented by a geometry, so if you need this, simply use a textured
billboard with lighting disabled or a sphere/whatever with emissive
colors defined. The lightsource example can show you the light source
part. The rest is basic OpenGL knowledge and there are a lot of examples
for this. If you have further osg-centric questions feel free to ask.
Cheers
Sebastian
