[name]
A geometric sphere defined by a center position and radius.
Constructor
[name]([page:Vector3 center], [page:Float radius])
center -- [page:Vector3]
radius -- [page:Float]
Properties
[property:Vector3 center]
[property:Float radius]
Methods
.set([page:Vector3 center], [page:Float radius]) [page:this:Sphere]
center -- [page:Vector3]
radius -- [page:Float]
Sets the center and radius.
[method:Sphere applyMatrix4]([page:Matrix4 matrix]) [page:Sphere this]
matrix -- [page:Matrix4]
Transforms this sphere with the provided [page:Matrix4].
[method:Vector3 clampPoint]([page:Vector3 point], [page:Vector3 optionalTarget])
point -- [page:Vector3] The point to clamp
optionalTarget -- [page:Vector3] The optional target point to return
Clamps a point within the sphere. If the point is is outside the sphere, it will clamp it to the closets point on the edge of the sphere.
[method:Sphere translate]([page:Vector3 offset]) [page:Sphere this]
offset -- [page:Vector3]
Translate the sphere's center by the provided offset vector.
[method:Sphere clone]()
Provides a new copy of the sphere.
[method:Boolean equals]([page:Sphere sphere])
sphere -- [page:Sphere]
Checks to see if the two spheres' centers and radii are equal.
[method:Sphere setFromPoints]([page:Array points], [page:Vector3 optionalCenter]) [page:Sphere this]
points -- [page:Array] of [page:Vector3] positions.
optionalCenter -- Optional [page:Vector3] position for the sphere's center.
Computes the minimum bounding sphere for *points*. If *optionalCenter* is given, it is used as the sphere's center. Otherwise, the center of the axis-aligned bounding box encompassing *points* is calculated.
[method:Float distanceToPoint]([page:Vector3 point])
point -- [page:Vector3]
Returns the closest distance from the boundary of the sphere to the point. If the sphere contains the point, the distance will be negative.
[method:Box getBoundingBox]([page:Box optionalTarget])
optionalTarget -- [page:Box]
Returns a bounding box for the sphere, optionally setting a provided box target.
[method:Boolean containsPoint]([page:Vector3 point])
point -- [page:Vector3]
Checks to see if the sphere contains the provided point inclusive of the edge of the sphere.
[method:Sphere copy]([page:Sphere sphere])
sphere -- [page:Sphere] to copy
Copies the values of the passed sphere to this sphere.
[method:Boolean intersectsSphere]([page:Sphere sphere])
sphere -- [page:Sphere]
Checks to see if two spheres intersect.
[method:Boolean empty]()
Checks to see if the sphere is empty (the radius set to 0).
