    1. COI think you're right that I'm doing the normals / normal indices wrong. It looks like in normalVectorsToNormalArrays() I'm only adding one normal per face. What I think I should be doing (and correct me if I'm wrong), is I should be adding a normal for each vertex. I'll try to fix that tomorrow and see if I get better lighting results. Thanks for the pointer!

    2. COI'm now loading a normal for every vertex (is that right, or should it be 1 normal for each face?). But I'm loading the normals in their .obj file's index order, so this obviously still isn't working properly, because like you said, the normals and the vertices **must share the same index**... I'm having a hard time trying to visualize how to achieve this and the pseudo-code at the link you gave me isn't making a whole lot of sense to me (I've been reading it over and over), nor is google turning up anything useful. I'll keep trying things, but could you (or someone) give me more advise?

    3. COMy first advice would just be to not reinvent the wheel and go download Assimp (http://assimp.sourceforge.net/), so you can get on with more interesting things :) . I don't have time for a full blown explanation, but if you want to do it yourself it boils down to: create a new vector of structs called "vertex" that contain position, normal, texcoord, etc. Then go through the obj file and every time you find a unique pair of position/normal/texcoord, copy the data into a new vertex so that it's all together (a STL map is useful for detecting duplicates). Then use this new vector to draw from.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
