Narrow Phase: Ray Trace Narrow Phase
The RayTraceNarrowPhase component is a narrow phase component, which is used in a collision pipeline. This method traces a ray for each point in one object following the oposite of the point’s normal up to find a triangle in the other object. Both triangles are tested to evaluate if they are in a colliding state.
It must be used with a TriangleOctreeModel, as an octree is used to traverse the object.
The CollisionModel at the lowest level is saved, in this case it must be a TriangleOctreeModel. If the octree would not be constructed already, build it. Then, rays are traced against the TriangleOctreeModel. Distances computed with the ray indicates if a collision occurs between the pair of TriangleOctreeModels. Finally, the DetectionOutput vector containing elements of TriangleOctreeModels in collision is returned, as well as the contact points on the triangle of each model.
Example of Usage
This component can be used as follows in XML format:
Colliding objects must have a TriangleOctreeModel:
