very slow if display view again if view has surface

[hainm]

# 1st cell
import nglview as nv

view = nv.show_file('../ngl/data/1crn_apbs_pot.dx.gz')
view

# 2nd cell
view

The current implementation is to store a series of commands in view, if display 2nd times, those commands (e.g: loadFile) will be executed again for 2nd view.

@arose any idea solution? Clearly that I don't understand much about MVC model.

In the view in the second cell, all ngl related things are executed again. In principal you could just do the rendering on a new canvas but that is not implemented in ngl.

[hainm]

is that something you would do in the future?

[arose]

no specific plans, will keep in mind when creating a separate renderer module

thanks, close now.
