Pytheas is a galactic exploration, vehicle based, construction game. It has been in development since December 2010. A fleet from Earth's Exploratory Force has gone missing; you are sent to find it. After finding the aptly named ship, Pytheas, you could return to earth, report the find, and let a collection of search and rescue efforts do the rest. However, realizing that is boring, you decide to scour the nearby star systems with your brand new, eerily empty inter-stellar mammoth. Pytheas gives players the tools to execute thier ideas without the limitations of a game engine designed with a different purpose in mind. Barriers that limit how you can play are removed to allow for more freedom.
When I started the project, I tried several physics engines but none of them had everything needed to make the game/engine possible. Luckily I'm a scientist, so I started building my own physics library. I've adapted the v2 physics engine (which works best with the v2 terrain) to work fairly smoothly on the very pointy v1 terrain.
You'll likely notice some frame rate issues when craters are being formed. This is caused by some of the calls used in the v1 engine directly rebuilding the model. When the craters are formed the models are being rebuilt rapidly and many time per frame. Once I integrate the algorithm that caps the number of rebuilds per second the frame rates will be smoothed out and your eyes won't notice the difference.
