I have 3d models made in Blender. I need to load them for further rendering using OpenGL ES.
I also want to implement picking, so I need to know object dimensions. So far I did not find option like “export dimensions” while exportiong to wavefront obj in Blender. I decided to calculate them manually.
So, I have vertex and face data. How do I calculate object dimensions? It may be done roughly, whatever. Or maybe I’m on the wrong tracK?
Isn’t it just the minimum and maximum coordinate value found for each vertex for each of the X, Y and Z axes?
