Teapot GLSprite - How do I convert data to this format

[zacware]

I was trying to use GLSprite code to start learning some opengl stuff. looking at glsprite i see the arrays of vertices and normals, which makes sense, but I don't understand the purpose of the indices table (drawing order i assume?) but if I wanted to use a 3d program like blender to import some 3d graphics for use in an iphone program, how to do convert data to the teapot.h format with arrays for vertices, normals and indices.

I have a similar question. Can anyone give an explanation of the "normals" data as implemented in the GLGravity sample?

How would I calculate the normals for a given array of vertices and indices in order to render properly (effectively changing the teapot.h model data into a simple cube)??

I guess whats really throwing me off is the RunLengthEncoded Array: short new_teapot_indicies[]

Can anyone clarify how the data is being used?
