3D Figure Inside a 3D Figure - is it possible?
in [Matlab]

From: Ahmed Hussain on 9 Mar 2010 02:52 Dear Steve, Can you help me knowing how to load and display a 3D model in DirectX file (.x file). I have two 3D models and I have to load and display them in MATLAB. The rotation and translation can be done using cameratoolbar. Thanks, Best Wishes, Ahmed H.

No, I can't, as I have not worked directly with DirectX files. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ |
