Constructor & Destructor Documentation

CLoad3DS::CLoad3DS (    ) 
 

This file handles all of the code needed to load a .3DS file. Basically, how it works is, you load a chunk, then you check the chunk ID. Depending on the chunk ID, you load the information that is stored in that chunk. If you do not want to read that information, you read past it. You know how many bytes to read past the chunk because every chunk stores the length in bytes of that chunk.
