That’s the cheating way.

Bounce the energy orb over the glass in the no-portal orb-maker/collector room

Put the portal on the ceiling next to the glass to bounce the orb off the slant and into the collector in the main room

I’m not sure if this is the way you’re SUPPOSED to do it, but in the two-door room I climbed over my companion sphere and then bounced it off the floor onto the other button before shooting the portal for the orb, it took like 50 tries though
