    <p>I'm trying a packing problem using Python and OBJ files. I'm a novice in python and not sure how to manipulate the OBJ file vertices to find the optimal bounding box. Any sample python code to get me started? Here's a simple box OBJ file to start with which I'll need to fit into a larger container. In short, can object X fit into object Y. Then ultimately how many x can fit into Y with the most optimal solution, but that's for way later.</p> <p>Here's the .OBJ files for the small and bigger boxes Small:</p> <pre><code># Rhino </code></pre> <p>v -5 -5 0 v -5 -5 5 v 0 -5 0 v 0 -5 5 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 -1 0 vn 0 -1 0 vn 0 -1 0 vn 0 -1 0 f 4/4/4 2/2/2 1/1/1 3/3/3 v 0 -5 0 v 0 -5 5 v 0 0 0 v 0 0 5 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 1 0 0 vn 1 0 0 vn 1 0 0 vn 1 0 0 f 8/8/8 6/6/6 5/5/5 7/7/7 v 0 0 0 v 0 0 5 v -5 0 0 v -5 0 5 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 1 0 vn 0 1 0 vn 0 1 0 vn 0 1 0 f 12/12/12 10/10/10 9/9/9 11/11/11 v -5 0 0 v -5 0 5 v -5 -5 0 v -5 -5 5 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn -1 0 0 vn -1 0 0 vn -1 0 0 vn -1 0 0 f 16/16/16 14/14/14 13/13/13 15/15/15 v -5 -5 0 v 0 -5 0 v -5 0 0 v 0 0 0 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 0 -1 vn 0 0 -1 vn 0 0 -1 vn 0 0 -1 f 20/20/20 18/18/18 17/17/17 19/19/19 v -5 -5 5 v -5 0 5 v 0 -5 5 v 0 0 5 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 0 1 vn 0 0 1 vn 0 0 1 vn 0 0 1 f 24/24/24 22/22/22 21/21/21 23/23/23</p> <p>Bigger box:</p> <pre><code># Rhino </code></pre> <p>v 0 0 0 v 0 0 20 v 0 20 0 v 0 20 20 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn -1 -0 -0 vn -1 -0 -0 vn -1 -0 -0 vn -1 -0 -0 f 4/4/4 3/3/3 1/1/1 2/2/2 v 0 20 0 v 0 20 20 v 20 20 0 v 20 20 20 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 1 0 vn 0 1 0 vn 0 1 0 vn 0 1 0 f 8/8/8 7/7/7 5/5/5 6/6/6 v 20 20 0 v 20 20 20 v 20 0 0 v 20 0 20 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 1 0 0 vn 1 0 0 vn 1 0 0 vn 1 0 0 f 12/12/12 11/11/11 9/9/9 10/10/10 v 20 0 0 v 20 0 20 v 0 0 0 v 0 0 20 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 -1 0 vn 0 -1 0 vn 0 -1 0 vn 0 -1 0 f 16/16/16 15/15/15 13/13/13 14/14/14 v 0 0 0 v 0 20 0 v 20 0 0 v 20 20 0 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn -0 -0 -1 vn -0 -0 -1 vn -0 -0 -1 vn -0 -0 -1 f 20/20/20 19/19/19 17/17/17 18/18/18 v 0 0 20 v 20 0 20 v 0 20 20 v 20 20 20 vt 0 0 vt 0 1 vt 1 0 vt 1 1 vn 0 0 1 vn 0 0 1 vn 0 0 1 vn 0 0 1 f 24/24/24 23/23/23 21/21/21 22/22/22</p> <pre><code>enter code here </code></pre>

    1. COyour question isn't clear at all. If you want to compute a bounding box of an object just take the min and max x, y, z value of each vertex. What does that have to do with fitting different models?

    2. COdon't i need to find the bounding box first to see if one fits into another?

    3. COFit in what sense? That one bounding box is larger than another? Or that one object could be completely 'within' the mesh of the other (very hard problem to solve)? Or do you mean something else by 'fitting' ?

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.
