class BoundingVolumeBase
package away3d.bounds
extended by AxisAlignedBoundingBox, BoundingSphere, NullBounds
Available on all platforms
An abstract base class for all bounding volume classes. It should not be instantiated directly.
Constructor
Variables
Methods
clone():BoundingVolumeBase
Clones the current BoundingVolume object
Returns:
An exact duplicate of this object
containsPoint(position:Vector3D):Bool
Method for calculating whether the given position is contained within the bounding volume.
Parameters:
position | The position in local coordinates to be checked. |
|---|
Returns:
A Boolean value representing the detection of a contained position.
disposeRenderable():Void
Disposes of the bounds renderable object. Used to clear memory after a bounds rendeable is no longer required.
fromExtremes(minX:Float, minY:Float, minZ:Float, maxX:Float, maxY:Float, maxZ:Float):Void
Sets the bounds to the given extrema.
Parameters:
minX | The minimum x value of the bounds |
|---|---|
minY | The minimum y value of the bounds |
minZ | The minimum z value of the bounds |
maxX | The maximum x value of the bounds |
maxY | The maximum y value of the bounds |
maxZ | The maximum z value of the bounds |
fromGeometry(geometry:Geometry):Void
Updates the bounds to fit a Geometry object.
Parameters:
geometry | The Geometry object to be bounded. |
|---|
fromSphere(center:Vector3D, radius:Float):Void
Sets the bound to fit a given sphere.
Parameters:
center | The center of the sphere to be bounded |
|---|---|
radius | The radius of the sphere to be bounded |
fromVertices(vertices:Vector<Float>):Void
Updates the bounds to fit a list of vertices
Parameters:
vertices | A Vector.<Number> of vertex data to be bounded. |
|---|
isInFrustum(planes:Vector<Plane3D>, numPlanes:Int):Bool
Tests if the bounds are in the camera frustum.
Parameters:
mvpMatrix | The model view projection matrix for the object to which this bounding box belongs. |
|---|
Returns:
True if the bounding box is at least partially inside the frustum
overlaps(bounds:BoundingVolumeBase):Bool
Tests if the bounds overlap other bounds, treating both bounds as AABBs.
rayIntersection(position:Vector3D, direction:Vector3D, targetNormal:Vector3D):Float
Method for calculating whether an intersection of the given ray occurs with the bounding volume.
Parameters:
position | The starting position of the casting ray in local coordinates. |
|---|---|
direction | A unit vector representing the direction of the casting ray in local coordinates. |
targetNormal | The vector to store the bounds' normal at the point of collision |
Returns:
A Boolean value representing the detection of an intersection.
