I have just point cloud data... [ X Y Z ] . and want to convert into triangle mesh. for example i have point cloud *ply file and want it to convert into mesh *ply.

-104.935527 -79.480870 -4.162239

-102.857596 -79.480870 -4.162239

there much b faces information... at the end..

1. is there any 3D library that can convert point cloud to mesh.
2. or any software ?

thanks

Look up delaunay triangulation.

I have a couple of sample Direct3D programs implementing it with source code in my samples folder but I am unable to figure out where I got them from.

You should take a look at Hugh Hoppe's research[url="http://research.microsoft.com/en-us/um/people/hoppe/"]http://research.microsoft.com/en-us/um/people/hoppe/[/url]
His thesis is about reconstructing 3d surfaces from points.

If you're looking for an existing implementation then you can try [url="http://meshlab.sourceforge.net/"]meshlab[/url]. It has several surface reconstruction filters you can choose from and it supports the .ply format (among many others).
