I have thousands points that I took from kinect for 3D scanner. I can see the 3D shape in meshlab or blender but I want to convert all points according to .obj file format.
here is an example of .obj file ;

# Simple object file . This is comment
v -0.500000 0.000000 0.400000
v -0.500000 0.000000 -0.800000
v -0.500000 1.000000 -0.800000
v -0.500000 1.000000 0.400000
f -4 -3 -2 -1

I just have v points but dont know how to convert them to f (face). If there is no f(face) I cannot see the real shape in interface.
Thanks in advance. If question is not clear enough please comment.

Why in obj format?

my interface expects obj file. I dont have any tools to show those thousands points that I took from kinect in interface.

inside of .obj file is defferent from the file that I keep points from kinect. I just have vertices but I need to convert them to face also. Here is detailed explanation of face and vertice. http://www.mathsisfun.com/geometry/vertices-faces-edges.html

Obj files is not quite a legitimate format for data exchange. And the mere fact that the data could be hard-coded in the object file is just an indication of the abuse of technology.

Yes you are right Mr. Sergey. I agree. But we write the points to file.obj . I though we could obey the obj file format while writing the points in file with some calculation or something else. :)

Is it possible just to link this .obj file and get data? Anyway, I would review such a weird architecture. I is not guaranteed to survive for long anyway, is completely unportable...

Have you checked the documentation for this file format? In general a .obj file is the object code output from a compiler. The sample you have shown is just ordinary text.

Yes I checked it very well. all points that I took from kinect are just v points. There must be f(face) also. I need a code to take points and arange them according to obj file. But I cant find it. Thanks for caring

I an not sure you checked it. Please see my comment above.
