Gama usage question

Hi List (Ales)

I have a usage question for Gama. I don't think it is the right tool 
but I hope it is. Perhaps my point-cloud can be thought of as a 
large geodetic network...

I have a large point-cloud. I would like to convert coordinate 
systems, a 7-DOF rotate, translate, and scale.

For example, I know point #42 is at position (1,2,3). And I know 
point #42424 is at (41,42,43). I have 10,000 other points as part of 
this point cloud. I know 'real world' coordinates of the two example 
points, for example, I want point #42 at latitude, longitude, and 
altidude (lat0,lon0,alt0), and the other point should be at 
(lat1,lon1,alt1). All other 10k points should transform accordingly.

Is gama the right tool for this?

Could it be with some pre-processing of the data? For example, would 
I need to convert all other points to be (altitude, azimuth, range) 
in reference to one of the known points?

My point cloud is currently PLY file with X,Y,Z, R,G,B, and normals. 
Can Gama handle this? If not, is the output order the same as the 
input, in which case I can re-combine RGB with the adjusted XYZ?

Thanks for any tips on whether or not this is the right tool. I hope 
so, I know of no other command-line tools that can do georeferencing 
and transformation of point clouds.

Thanks,
