Polar Elephant

Common bugs
in Havok, PhysX, Bullet, ODE, Ogre, Newton.. SOLVED!

Bug 1.) Few subSteps: "Moon gravity effects"
bUg 2.) A lot of subSteps: "Spiraling to death"
buG 3.) Interpolation VS. Temporal Distribution

Common mistakes
related to fixedTimeStepping - UNCOVERED:

4.) Design-Time Planning and Recognition of Hardware Min. Sys. Requirements
5.) "Scaling the World": Gravity, Mass, Size and Hidden Effects of fixedTimeStepping
6.) Jitter, Wobbles, Choppiness and Slowdowns: Unstable Physics & Smooth Animation

Common pitfalls
for any kind of simulation, say - MOLECULAR DYNAMICS

- x86 binaries should work on any Linux PC with or without X11
- arm binaries should be compatible with Linux mobile device

Qtopia port (source code + static Linux binary)

Completely re-written AI, there are now battles going on in universe that are independent of player, pirates attacking trader convoys, police patrols attacking pirates or even complete war outbreaks.... this "Elite remake" should be in par with ArcElite (Archimedes Elite), well at least that was my goal... but there is more, hard-coded 7 extra missions and added many other features that appeared in Elite remakes and some completely new stuff...

MISSION 1. - Bad dream
After launch you notice unusually large number of viper patrols and other space ships around the station and they soon start shooting at each other... and you. This is a good time to warm up and get some score/rating. (Go after bad guys for extra points)

MISSION 2. - Asteroid shower
In 'real life' on Lave Space Station things are not much better. Large number of Asteroids is heading for the planet. Opportunity to earn some cash here. (When reinforcement arrive be quick or they'll shoot off your money)

MISSION 3. - Zurid Pino and Cloaking Device
Nasty pirate is menacing peaceful trading region and it has Cloaking Device. Later on you are told that pirate might be infamous Zurid Pino and that you better get E.C.M. There is also a reward if he is captured alive. Once you meet him you will find out that ship can not be missile targeted and scanner has problem tracking it. (For bonus reward and cash don't destroy the ship until Pino launches Escape Pod. When he bails quickly destroy the Cougar and only then catch up and scoop Pino's capsule. After that hurry up and scoop the cargo and other debris before it drifts away. Before you scoop anything check if you have enough space in your Cargo Hold, if not jettison less valuable items and shoot them for points)

MISSION 4. - Supernova
After arriving at Razaar system your on-board computer displays a message that fuel leak is detected. That actually is the least of your troubles as soon you will find out that that Razaar's sun is going "Nova". It's complete chaos and the station is out of Hyperspace fuel but at least they will supply you with a new ship. The new ship comes with important passengers and a new mission, but first you must survive Supernova. (Clear off all the traffic running away from the planet, then once you are far away to engage Warp Jump engine be sure to have planet and sun in you REAR View because you'll need to be far, far away to survive Supernova blast... look for new planet description if mission completed successfully then scoop either of two suns for fuel)

MISSION 5. - Asteroids on Qube system
Same as 2nd mission, but this time there are other pilots around from the start and you will have to be quick to earn your money. (You may notice a new gadget in your ship, a gift from Razaar refugees to help you keep track of your missile target)

MISSION 6. - Constrictor
Her Majesty's Space Navy makes note of you and gives you the mission to catch pirates that have stolen top-secret experimental naval ship prototype. This is a classic unchanged mission from the original BBC Elite. (For bonus reward capture the crew alive. Since police chased them away of station before they re-fueled you will find them near the sun trying to scoop)

MISSION 7. - Genesis Capsules
"...We need to find some other way of releasing Ecology Seed and dispersing it in the planet's atmosphere. Simultaneous activation at low altitude is the best we can try now without proper equipment. Capsules are being loaded in your ship in special food containers. ---MESSAGE ENDS." (At low altitude jettison all the containers and activate Energy Bomb... look for new planet description if mission completed successfully)

MISSION 8. - Thargoid documents
As in original Elite - "I have obtained the defence plans for their Hive Worlds. The beetles know we've got something but not what. If I transmit the plans to our base on Birera they'll intercept the transmission. I need a ship to make the run. You're elected. The plans are unipulse coded within this transmission. You will be paid. Good luck Commander. ---MESSAGE ENDS."

MISSION 9. - The Battle For Birera (Thargoid Invasion)
"...The Hive World plans have been retrieved from your on-board computer and decoded successfully. The future of the whole Galaxy may now be in our hands. Birera Station must be defended at all cost. Die hard Commander. ---MESSAGE ENDS."

Have Fun!
