In your XNA project, you re ready to store the position of your four wheels. It depends on the structure of your Model and which ModelMesh corresponds to which wheel. You can use the code of recipe 4-8 to visualize the structure of your Model. For each wheel, you should know the ID of the corresponding ModelMesh. Once you know the ID, you can access the lowest position of each wheel and store it in a variable. Although you can make the following code four times as compact as shown here using a simple for loop, I ll always use four separate variables with a somewhat intuitive name for each of the wheels. The front-left one is abbreviated to fl, the back-right one to br, and so on. int int int int flID frID blID brID = = = = 5; 1; 4; 0;

Remember, you need to use the correct IDs for your specific Model, which you can find using recipe 4-8. The positions you have stored in the Tag properties of the ModelMeshes are relative to the origin of the ModelMesh. You want to know them in the same space as your terrain, which is in absolute 3D space. A first step toward this goal would be to find the position of your lowest vertices relative to the origin of the Model, which can be done by transforming them with the absolute transformation matrix of the ModelMesh (see recipe 4-9). Next, because you will probably also use a World matrix to render the Model at a certain position in the 3D world, you should combine the Bone matrix of each ModelMesh with the Model s World matrix. myModel.CopyAbsoluteBoneTransformsTo(modelTransforms); Matrix frontLeftMatrix = modelTransforms[myModel.Meshes[flID].ParentBone.Index]; Matrix frontRightMatrix = modelTransforms[myModel.Meshes[frID].ParentBone.Index]; Matrix backLeftMatrix = modelTransforms[myModel.Meshes[blID].ParentBone.Index]; Matrix backRightMatrix = modelTransforms[myModel.Meshes[brID].ParentBone.Index]; Vector3 frontLeft = Vector3.Transform(frontLeftOrig, frontLeftMatrix * modelWorld); Vector3 frontRight = Vector3.Transform(frontRightOrig, frontRightMatrix * modelWorld); Vector3 backLeft = Vector3.Transform(backLeftOrig, backLeftMatrix * modelWorld); Vector3 backRight = Vector3.Transform(backRightOrig, backRightMatrix * modelWorld); First, you calculate the absolute transformation matrix for all Bones of the Model (see recipe 4-9). Next, for each wheel, you find the absolute transformation matrix stored in the Bone corresponding to the ModelMesh of the wheel. Once you know the absolute transformation matrix for each wheel, you combine this matrix with the World matrix of the Model and use the resulting matrix to transform your vertices. The resulting Vector3s contain the absolute world 3D coordinates of the lowest vectors of your Model s wheels.

Note As explained in detail in recipe 4-2, the order of matrix multiplication is important. Because these vertices are part of the Model, first you re taking the offset between the (0,0,0) absolute 3D origin stored in the World matrix into account, and afterward you re transforming your vertices so they become relative to the Model s origin. Doing things this way, your World matrix has an impact on the Bones of your Model, which is what you want. If you did this the other way around, any rotations contained in the Bones would have an impact on the World matrix. See recipe 4-2 for more information on the order of matrix multiplication.

Retrieving the Height of the Terrain Underneath the Model
Now that you ve found the absolute 3D positions of the four wheels, you re almost ready to find the required rotation angles. As a start, you want to find how much you should rotate the Model around its Side vector so the front of the car is lowered or raised. Instead of working with all four points, you re going to base your calculations on two points only. The first point, front, is positioned between the front wheels, while the second point, back, is between the two back wheels, as illustrated in Figure 4-23. You want to find the rotation so the dotted line frontToBack (that connects both points) is aligned with the terrain underneath.
Figure 4-23. Points of interest when tilting a car You can find the position of both points easily by taking the average of their neighboring wheels. You can find the vector between them, backToFront, by subtracting them from each other: Vector3 front = (frontLeft + frontRight) / 2.0f; Vector3 back = (backLeft + backRight) / 2.0f; Vector3 backToFront = front - back; Remember, you want to find how much you should rotate your car around its Side vector, so its front point is moved upward or downward. Ideally, you want your frontToBack vector to have the same inclination as the terrain slope, as shown in Figure 4-24. The angle you want to calculate is denoted fbAngle in Figure 4-24. You first need to find the height difference of the terrain at both points. Use the GetExactHeightAt method constructed in recipe 5-9: float frontTerHeight = terrain.GetExactHeightAt(front.X, -front.Z); float backTerHeight = terrain.GetExactHeightAt(back.X, -back.Z); float fbTerHeightDiff = frontTerHeight - backTerHeight;
