I'm trying to understand what it means to normalize a model. In working with databases, I normalize a database by making sure there is only one copy of any data in the database. My math skills are weak and I'm trying to understand what it means to normalize a model. If it means what I think it does (scale the model so that all points are between 0 and 1), then it might help me fix my problem of centering any model my app loads and keeping the camera in one direction ... or at least, it would make doing all this much easier. Then I wouldn't have to get the min and max x, y, and z values and figure out the centrioid because I would always know it. Does this make sense? If so, how is this done? Can anyone elaborate on this? Tell

Off the top of my head...
Find the centroid, C.
for every point, v, do v=v-C (center the object)
then find the longest v in the object, call that length max_length.
for every v, do v=v/(max_length).
