From an online tutorial I learned how to add some simple lights to my program. Now in the tutorial he uses normals to generate the lighting on his model. I was lazy and trying to be experimental and I tried lighting without Normals.
Now the lighting doesn’t seem right, but yet it still seems to work overall. My model has a gradient of lighting from one side to the other but I can’t make out individuals faces.
I’m wondering why is this, and what will adding normals do to my model? Will it make faces easier to see?
FYI: I have a generated terrain of faces so adding normals is not a minor job, although I know the math and will implement soon) I just wanted to understand lighting a bit more.
