Scaling objects

Hi,

I don't know if it is the right place for this question, but I am going to put it here because I also have a suggestion for a possible future request.
I need to obtain some projections from different PCs.
First, I have problems creating a trajectory using the tutorials, I can save viewpoints or a "trajectory.log" file. but I cannot create a trajectory that has for example 6 views (let's say from 6 faces of a cube) with my desired resolution (height and width). Are there any tutorials that show the whole pipeline for creating a trajectory either using an interface or a script?

I could create a trajectory by saving viewpoints using the tutorials and concatenating them manually. But of course, it works for the PC that I used to create viewpoints.
### So the question is :
Is it possible to scale PCs to their bounding box or the precision box (for voxelized PCs) before visualizing them? In this way, a single camera trajectory can be used for any object. If there is not such a possibility that would be great to add it.
