I have recently started to plan a project in Unity that will be for Android. I have a database that consists of over 150,000 stars (may trim this down if I/O cripples the overhead). The game will hopefully consist of a free-to-explore universe creating the illusion that the user is flying in a realistic representation of the stars.
My biggest concern at the moment is how do I create a realistic environment with these starts, while keeping the resource impact on the phone to a minimum? Some people mentioned using octrees, would this be wise?
This is my first game that I am looking to create so any help would be much appreciated to this novice!
