How to define zoom, perpective, material... before to export HTML archive?

Hello, I would like to share my 3D with clients but I don’t want to enable UI. How to define view parameters before exporting model ?
I understood, point of vue is 0,0,0 but vue is in orthographic mode and zoom is too close of my model… Is it a way to export model with the same parameters as in the perpective view ?
I’m using Rhino 6 on Mac.
Thanks,
Henri
