I want to use their .wrl files (listed as 1HHO-ribbon-bychain.zip) because it has color unlike the .stl.
When I try to open the file in Meshlab it takes a very very long time to load, and then crashes at the point when my machine runs out of memory (I can watch Meshlab in task manager rise up to about 10GB). The problem is that there are millions of unreferenced vertices in this file. I know this because other similar molecule models from the site that I have opened have had like 12mil vertices and then when I remove unreferenced ones it goes down to less than 50k.
My question is whether there is some clever way to remove these unreferenced vertices as the file is being opened, or open the file in smaller parts.
Thanks in advance for your help.
