I am trying to use lighting on point data (using GL_POINTS) but it doesn’t seem to have any affect. I am using the same GL commands that I use on facet data and it works with that.
Is there anything special I have to do to enable lighting for point data? Or can I even do lighting on point data, for that matter? Also, do I need to define the normal for the point data? I’ve tried both ways and that doesn’t seem to help either.
