I posted about this below but not sure now if my subject was accurate. I am looking for an example of doing this (creating a pt light src) that can be applied to a sphere rendered by gluSphere (not sure if this matters but thought I would mention).
I’d appreciate any info anyone could give asap.
Thanks very much!
Just to see if I understand correctly, you want to make it appear that your gluSphere is emitting light?
There are a couple of things you need to do if this is the case.
- Create a light at the same location as your sphere. (Using glLight* functions to set the position, etc.)
- Draw your sphere at that location, giving it an emissive material color. (Using the glMaterial* functions)
If you just do number 2, your sphere will appear to be giving off light for itself, but it won’t actually light anything else, thus the need to put number 1 in there.
Yes, this is what I was looking for.
Yeah, right now have been given a sample with just the sun giving off light on itself only
Thanks a lot.
