Public Member Functions | |
| void | addTriangle (Triangle t) |
| Adds a triangle to the model. Only works if bb hierarchy is not built yet. | |
| void | build () |
| Builds the bbox hierarchy. Recursively calls split on the root. | |
| void | cloneModel (CollisionModel *original) |
| This model will share the bbox hierarchy of the original. | |
| CollisionModel (int threadId) | |
| Creates an empty collision model with no geometry and a tree with just an empty Leaf root. | |
| void | getBoundingVolumes (int depth, std::vector< BoundingBox > *bvs) |
| const Node * | getRoot () const |
| int | getThreadId () const |
| const transf & | getTran () const |
| bool | isActive () const |
| void | reset () |
| Destroys the bb hierarchy, but does not save the triangles that it contained. | |
| void | setActive (bool act) |
| void | setTran (const transf &t) |
| ~CollisionModel () | |
| Also deletes the bb hierarchy, if this model is not a clone. | |
Private Attributes | |
| bool | mActive |
| bool | mClone |
| Tells us if this model is a clone of another model. | |
| Node * | mRoot |
| int | mThreadId |
| The id of the thread that this body was added in. | |
| transf | mTran |
The collision model contains its bb hierarchy, a transform and a flag indicating whether it is active or not. It is the only public interface with the bb hierarchy: a model is created with a number of triangles, then it is asked to build its own bb hierarchy.

| Collision::CollisionModel::CollisionModel | ( | int | threadId | ) | [inline] |
Creates an empty collision model with no geometry and a tree with just an empty Leaf root.
Definition at line 182 of file collisionModel.h.
| Collision::CollisionModel::~CollisionModel | ( | ) | [inline] |
Also deletes the bb hierarchy, if this model is not a clone.
Definition at line 189 of file collisionModel.h.
| void Collision::CollisionModel::addTriangle | ( | Triangle | t | ) |
Adds a triangle to the model. Only works if bb hierarchy is not built yet.
After all the triangles have been added, use build() to build the bb hierarchy. Use reset() to clear the bb hierarchy of an already built model.
Definition at line 467 of file collisionModel.cpp.
| void Collision::CollisionModel::build | ( | ) |
Builds the bbox hierarchy. Recursively calls split on the root.
Definition at line 499 of file collisionModel.cpp.
| void Collision::CollisionModel::cloneModel | ( | CollisionModel * | original | ) |
This model will share the bbox hierarchy of the original.
This model does not have its own bbox hierarchy, but instead uses the one of the original model. WARNING: the entire cloning system is not completely finished. If the original is changed or deleted then the clone is almost guaranteed to cause a crash!
The clone can also be created (when using the constructor) in a different, thread than the original, which is the way cloning is most usually applied.

| void Collision::CollisionModel::reset | ( | ) |
Destroys the bb hierarchy, but does not save the triangles that it contained.
In the future, this should also have a version where all the triangles that used to be in the hierarchy are centralized back in the root. Does not work for clones.

int Collision::CollisionModel::mThreadId [private] |
The id of the thread that this body was added in.
This marker helps us keep track of bodies that are specific to a given thread. See the threading functions of the CollisionInterface for details.
