3D virtual & physical modeling

Recommended Posts

The CHI website infers that RTIs can be used for "3D."


Obvisouly the calculated surface normals and viewers do relay 3D texture information, but have you ever seen RTI/PTM data used for 3D computer or physical models?


For example converting them into a conventional 3D computer model for use in CAD, animation, or other 3D computer software?

Hi Jason,


This issue was actually covered in another topic discussion:



Bottom line is that normal data *IS* 3D data, though it isn't points in cartesian space. When you convert the normal data to a 3D surface there is an uncertainty that accumulates, so you have a warping problem. See the post for the rest of the details and links to some papers on this.
