| | 13 | * Run "scons" |
| | 14 | |
| | 15 | == General Controls == |
| | 16 | * ![1] Fly the plane. <-- Use one of these if you crash. |
| | 17 | * ![2] Drive the car. |
| | 18 | * ![3] Drive the boat. |
| | 19 | * ![4] Go for a walk. |
| | 20 | * [m] Toggle between first-person and third-person view. |
| | 21 | * [g] Toggles full-screen mode. |
| | 22 | * [i] Resets the scene to its initial configuration. |
| | 23 | * [q] Exit. |
| | 24 | |
| | 25 | == The Plane == |
| | 26 | * [f] Moves the plane forward and pauses motion of the plane. |
| | 27 | * [w] Makes the plane accelerate, unpausing it if it is paused. |
| | 28 | * [s] Makes the plane slow down, unpausing it if it is paused. |
| | 29 | * [a/d] Roll the plane (rotate about its Z axis). |
| | 30 | * [left/right arrows] Yaw the plane (rotate about its Y axis). |

| | 50 | == Environment Information == |
| | 51 | This flight simulator takes plane around Cory Island, a C-shaped piece of |
| | 52 | land named after its creator and containing everything he could fit on it in |
| | 53 | a reasonable amount of time. |
| | 54 | |
| | 55 | The island is formed by combining several mathematical functions with the |
| | 56 | midpoint subdivision algorithm to create its very specific shape while |
| | 57 | containing randomly-generated mountains on a single heightmap. First, the |
| | 58 | midpoint subdivision algorithm is performed on the left (looking at it as a |
| | 59 | C) half of it. This is then tapered linearly down to the right half so that |
| | 60 | there are no cliffs immediately adjacent to the flat part. The distance to a |
| | 61 | circle of the desired size of the C is calculated at each point in the |
| | 62 | heightmap, and it is raised up if it is determined to be on the C or clamped |
| | 63 | to zero if it is not. It is slightly tapered if it is near the edge. |
| | 64 | Finally, a small opening is cut out to make the "O" into a "C," again, |
| | 65 | tapering it to make a smooth beach. This is the final form of the C. |
| | 66 | |
| | 67 | Surface normals are then estimated for each grid square on the height map, |
| | 68 | and then these are averaged for each vertex, producing a smooth set of |
| | 69 | normals to be used for lighting calculations. |
| | 70 | |
| | 71 | == Extensions == |
| | 72 | * The addition of the car and boat as well as Mr. Egghead from project 2 are |
| | 73 | extensions. |
| | 74 | * If the plane crashes into the ground, water, or a building, it explodes. If |
| | 75 | the car collides with a building or dives into water, it explodes. If the |
| | 76 | boat hits land, it explodes. Mr. Egghead is invulnerable. |
| | 77 | * When you crash, the camera goes into a special "explosion-vision" mode. Use |
| | 78 | the 1-4 keys to go back to a normal mode. |
| | 79 | * The car uses very simple physics to allow it to drive on sloped surfaces. |
| | 80 | * The boat uses even simpler controls. |
| | 81 | * Mr. Egghead is a simplified version of what I used for project 2. |
| | 82 | * The trees are simple fractals. There are simple clouds in the sky. |
| | 83 | * The water is animated. |
| | 84 | * The plane has slightly more advanced (but still oversimplified) physics than |
| | 85 | was required. It climbs less (or falls) when not oriented normally, for |
| | 86 | instance. |
| | 87 | |
| | 88 | == Known Bugs == |
| | 89 | * Lots of collisions aren't handled, and most that are should be handled |
| | 90 | better. |
| | 91 | * In extreme circumstances, the car noticably clips through the ground. |
| | 92 | * Mr. Egghead moves faster when going uphill. |
| | 93 | * The trees should be randomly generated. |
| | 94 | * The boat should have a proper model. The airplane and car models are also |
| | 95 | very bad. The textures are bad. |
| | 96 | * The camera should be prevented from going inside of the ground and buildings. |
| | 97 | * The car can drive in the air. |
| | 98 | * You can see the seams in the sky box. |
