public interface VoxelsPredicate
Modifier and Type | Method and Description |
---|---|
boolean |
anyExists()
Does at least one value satisfy the predicate - across all voxels?
|
int |
count()
Counts the number of values satisfying the predicate - across all voxels.
|
int |
countForObject(ObjectMask object)
Counts the number of values satisfying the predicate - but restricted to voxels corresponding
to on in an object-mask.
|
ObjectMask |
deriveObject(BoundingBox box)
Creates an
ObjectMask for all the voxels inside the bounding-box satisfying the
predicate. |
Optional<ObjectMask> |
deriveObjectTight()
Creates an
ObjectMask for all the voxels satisfying the predicate, minimally fitting
the bounding-box to the on voxels only. |
boolean |
higherCountExistsThan(int threshold)
Whether the count is greater than a particular threshold.
|
boolean |
lowerCountExistsThan(int threshold)
Whether the count is less than a particular threshold.
|
boolean anyExists()
The computational cost of the operation is O(n)
in the number of voxels in the
worst-case. Typically, it exits earlier.
int count()
The computational cost of the operation is O(n)
in the number of voxels.
int countForObject(ObjectMask object)
The computational cost of the operation is O(n)
in the number of voxels.
object
- the object-mask.boolean higherCountExistsThan(int threshold)
The computational cost of the operation is O(n)
in the number of voxels in the
worst-case. Typically, it exits earlier.
threshold
- the threshold.boolean lowerCountExistsThan(int threshold)
The computational cost of the operation is O(n)
in the number of voxels in the
worst-case. Typically, it exits earlier.
threshold
- the threshold.ObjectMask deriveObject(BoundingBox box)
ObjectMask
for all the voxels inside the bounding-box satisfying the
predicate.
Any voxels satisfying the predicate are set to on.
All other voxels are set to off.
Unlike deriveObjectTight()
, this operates only within a certain bounding-box, and
always uses an identical bounding-box for the created ObjectMask
as box
.
The computational cost of the operation is O(n)
in the number of voxels in box
only.
box
- bounding-box.box
.Optional<ObjectMask> deriveObjectTight()
ObjectMask
for all the voxels satisfying the predicate, minimally fitting
the bounding-box to the on voxels only.
Any voxels satisfying the predicate are set to on.
All other voxels are set to off.
Unlike deriveObject(BoundingBox)
, this operates all the voxels, and will
typically use a much smaller bounding-box (fewer voxels) to describe the on voxels.
The computational cost of the operation is O(n)
in the number of voxels in box
only.
Optional.empty()
