Hello, I am new to Mathematica and still in the trial phase and I am having a hard time achieving something I assume would be relatively simple to do in Mathematica:

What I want to do:

• a) Import a mesh from the file system then extract the data as a List.
• b) Transform the data by applying a matrix transform to all {x,y,z} vector.
• c) render a new mesh that results from the transformed data.

I found some examples of Import and a few other examples related to this so here is what I was able to do and what I could not do: - I am able to import a 3D file - I get a display of the file BUT I cannot extract {x,y,z} data from the file as list of vector coordinates. - I am able to perform matrices computation on list data I enter manually but then I cannot display the mash data on screen.

People familiar with OpenGL will recognize the above as basic steps of working with 3D models, I turned to Mathematica because it is supposed to provide a friendlier environment for 3D algebraic computations but I find myself struggling with the syntax, I think I need a bit of help or at least some pointers from people that have already done that.
