This lighting is driving me crazy, could someone help me?
I want to use a light to light a scene. I have a ground plane which get''s lit well. And I have an object which I load from a .3ds file. I calculate the vertex normals by using the cross product and then aplying this to all vertices of a face. So basically I should get a flat shaded object.
But the object doesn''t look right. Some faces get lit others don''t. There''s no transition. Either fully lighted face or no lighting at all (totally black).
So when I make the light move around the object it looks really weird, like the faces turning on and off.
could someone please tell me what I have to do to correct this? I''ve tried everything I could think of
That''s because you are using a per vertex lighting algo. To avoid that, take the object further from the light source, or do a per pixel lighting (to time consuming for real-time rendering, not even the newest cards do it), or use lightmaps.
Sorry for not going into details, it''s saturday''s night, and i''m going out
