[name]
Frustums are used to determine what is inside the camera's field of view. They help speed up the rendering process.
Constructor
[name]([page:Plane p0], [page:Plane p1], [page:Plane p2], [page:Plane p3], [page:Plane p4], [page:Plane p5])
p0 -- [page:Plane]
p1 -- [page:Plane]
p2 -- [page:Plane]
p3 -- [page:Plane]
p4 -- [page:Plane]
p5 -- [page:Plane]
Creates a frustum from the designated planes.
Properties
[property:Array planes]
Array of 6 [page:Plane planes].
Methods
[method:Frustum setFromMatrix]( [page:Matrix4 matrix] )
[method:Boolean intersectsObject]( [page:Object3D object] )
Checks whether the object's bounding sphere is intersecting the Frustum.
[method:Frustum clone]()
Return a copy of this Frustum
[method:Boolean set]( [page:Plane p0], [page:Plane p1], [page:Plane p2], [page:Plane p3], [page:Plane p4], [page:Plane p5] )
p0 -- [page:Plane]
p1 -- [page:Plane]
p2 -- [page:Plane]
p3 -- [page:Plane]
p4 -- [page:Plane]
p5 -- [page:Plane]
Sets the current frustum from the passed planes. No plane order is implicitely implied.
[method:Frustum copy]( [page:Frustum frustum] ) [page:Frustum this]
frustum -- The frustum to copy
Copies the values of the passed frustum.
[method:Boolean containsPoint]( [page:Vector3 point] )
point -- [page:Vector3] to test
Checks to see if the frustum contains the point.
[method:Boolean intersectsBox]( [page:Box3 box] )
box -- [page:Box3]
Check to see if the box intersects with the frustum.
[method:Boolean intersectsSphere]( [page:Sphere sphere] )
sphere -- [page:Sphere]
Check to see if the sphere intersects with the frustum.
