Unfortunately, reading viewhome.js did not make the question more clear for me.

May be SweetHome3DJSViewer.html even better suits for "full screening"; but all my attempts to tie canvas size to innerHeight and innerHeight, 100%, 100vh/100vw made it even smaller https://woodmouse.ru/test/view/test.html

There is a way of adaptive full screen canvas alinement - https://stackoverflow.com/questions/428 ... f-viewport

Is it possible to use this method in SweetHome3DJSViewer.html?

Yours, Daniel
