I have got an obj file of a year. I want to transfer it to mesh.The file has two variables v and f. I don't know how to use commands like delaunay,trisurf,meshgrid to make it into mesh. Help?Has nayone done something sililiar before?

mesh is for 3-D data. If you only have v and f, I am not sure how do you want to present it in 3-D. However, if you have x, y and z data in a vector, this post might help you.

Perhaps v and f represent vertex and face information? If that is the case you can use the patch command. patch objects have the properties Vertices and Faces. Read the documentation to ensure you set these values using the right format; you may not be able to apply the variables v and f directly without some preprocessing.

I just need to know what is f which is a 125731*3 matrix and number in each row is the same. I need to find someway to create faces thus I can use patch command.Thanks.
