I calculated the normals with:

Mat pcNormals;
Vec3d viewpoint_1(0, 0, 0);
computeNormalsPC3d(pc, pcNormals, 6, false, viewpoint_1);

Now the PLYs look like:

ply
format ascii 1.0
element vertex 38304
property float x
property float y
property float z
property float nx
property float ny
property float nz
end_header
0.000681958 -0.00157701 0.00381835 0.985197 0.0119866 -0.171006
....

And I tried the sample that you have refer. But I don't unerstand the outputs... I have PointClouds of an object with different views. for example one cloud shows the object from the front and the next pointcloud from 10° different angle an so on (every pointcloud sees only one side of the object). After all i want a 3D pointcloud of the whole object from the single point clouds.
Now I add two pointclouds to the sample, than I use the result and add another pointcloud to the sample. but nothing happens.

sorry for the amateur questions - opencv is new for me.

In my opinion, the dinosaur from the second image has to fit in to the scene, but this don't happen
