Thread Subject: Read a 3D model in Matlab

Hi,

 How can I read a 3D model in Matlab? 2D images can be read using imread command and can work. But how can I can read a 3D model?

Regards,
Bandara

In what format is the 3D model ? If is a vrml file yuo can use Virtual Reality Toolbox or Simulink 3D Animation.

You can find some STL import functions in the File Exchange.
Good luck, Jan

To read a 3D model use
[Tri,Pts]=PLYREAD(FILENAME,'TRI') % just for polygon type models

and using trisurf u can plot the model.

trisurf(Tri,Pts(:,1),Pts(:,2),Pts(:,3));
 

hope this helps you can use trimesh also..
