A compound shape, sub shapes can be rotated and translated. Sub shapes cannot be modified once the shape is constructed. Shifts all child objects so that they're centered around the center of mass.

|
overridevirtual |
Cast a ray against this shape. Allows returning multiple hits through ioCollector. Note that this version is more flexible but also slightly slower than the CastRay function that returns only a single hit. If you want the surface normal of the hit use GetSurfaceNormal(collected sub shape ID, inRay.GetPointOnRay(collected faction)).
Implements Shape.
|
overridevirtual |
Cast a ray against this shape, returns true if it finds a hit closer than ioHit.mFraction and updates that fraction. Otherwise ioHit is left untouched and the function returns false. Note that the ray should be relative to the center of mass of this shape (i.e. subtract Shape::GetCenterOfMass() from RayCast::mOrigin if you want to cast against the shape in the space it was created). Convex objects will be treated as solid (meaning if the ray starts inside, you'll get a hit fraction of 0) and back face hits against triangles are returned. If you want the surface normal of the hit use GetSurfaceNormal(ioHit.mSubShapeID2, inRay.GetPointOnRay(ioHit.mFraction)).
Implements Shape.

overridevirtual |
Collect the leaf transformed shapes of all leaf shapes of this shape. inBox is the world space axis aligned box which leaf shapes should collide with. inPositionCOM/inRotation/inScale describes the transform of this shape. inSubShapeIDCeator represents the current sub shape ID of this shape.
Reimplemented from Shape.
|
overridevirtual |
Check if inPoint is inside this shape. For this tests all shapes are treated as if they were solid. Note that inPoint should be relative to the center of mass of this shape (i.e. subtract Shape::GetCenterOfMass() from inPoint if you want to test against the shape in the space it was created). For a mesh shape, this test will only provide sensible information if the mesh is a closed manifold. For each shape that collides, ioCollector will receive a hit.
Implements Shape.

overridevirtual |
Get which sub shape's bounding boxes overlap with an axis aligned box
| inBox | The axis aligned box to test against (relative to the center of mass of this shape) |
| outSubShapeIndices | Buffer where to place the indices of the sub shapes that intersect |
| inMaxSubShapeIndices | How many indices will fit in the buffer (normally you'd provide a buffer of GetNumSubShapes() indices) |
Implements CompoundShape.
