A few quick questions:
I understand a plane normal and what it means. I don’t quite understand how a single point can have a normal though. Right now I’m just making each polygon’s vertex normal equal to the polygon normal, but it results in flat shading (obviously). How do I generate a normal for a point… is it an average of all the polygons’ normals that share that one vertex?
How can I find the name of the video card under Windows (for bug reporting purposes)?
How can I find how much V(ideo)RAM is left?
I’m using NeHe’s tutorials and am having the problems with ATIs and Voodoo cards (like it appears everyone else is). I’ve done some searching but haven’t found a clear answer to it yet. Any pointers?
