Hello everyone,

I am trying to write an object loader in c++. Currently, I have a file that is made up of many sub objects and I am having a little difficulty figuring out how to process the data.

First of all, here is an example of part of the file

o shape_brow_Plane.030
v 3.719171 7.430269 -0.000989
v 3.719171 7.366541 -0.000989

later on it also uses the usual vt and vn and f as well.
First of all, I am wondering what the extra numbers after the vertex co-ordinates are. Are they sub-faces for the object?
Second, I am wondering if vertex co-ordinates are globally maintained, or are they separate for each object.

I current have a loop that iterates through all of the v, vt, vn. However, I have a feeling I will need to change how the loop works in general. Any help is appreciated.

Thank you for your time and help.
