Star Citizen developer Cloud Imperium Games has released a new trailer for the PC space game--and it does not disappoint. The video serves as an introduction to Star Citizen's procedurally generated planet system. The video is called "From Pupil to Planet," and when you watch the video, you'll know why.

Everything you see in the video is "100 percent in-engine footage, rendered in real-time," Cloud Imperium says. The video explains that, since planets are so large they could never fit in memory, planet surfaces and procedurally generated on-demand at different levels of detail.

Cloud Imperium points out that what you see in the video is a work in progress, but it looks pretty darn impressive all the same.

In other Star Citizen news, the game's major Alpha 2.0 update has been released, and, after three years of crowdfunding, the project has now raised an astonishing $100 million. It's the most successful crowdfunding campaign of any kind in history.
