javascript - Create thumbnail for three.js scene -

i building website visualize biological neurons of animals. have list of neurons names in list , draw neuron 3 js when user presses it's name. problem have several hundreds of neurons , names don't give estimation shape user has press every neuron until finds looking for. can (automatically) create thumbnails rendering of each neuron , show beside neuron name? thinking way allows me go through neurons list , render them virtually (without showing them) , create thumbnails every 1 , save these images. possible done automatically?

i have seen screen shots 3 js requires p button hit , generates screen shot , opens in new tab , doesn't save it.

thank much.
