Tread Marks is an Off-Road Battle Tank Racing and Combat game. Unlike most off-road racing games, in Tread Marks you can actually put holes and scorch marks in the terrain, which last for as long as the race does and don't hurt performance. With a suitably powerful weapon, you can even dig yourself a new canyon, or level a significant chunk of the map. The terrain engine is a binary-triangle tree based dynamic view dependant Level of Detail height field renderer, taking complete advantage of fast 3D hardware accelerators, and allowing total run-time modification of the landscape. The desired level of detail can be adjusted on the fly to suit the performance of the system running the game, and the desired frame rate of the player.
