Types

type Space

type Space interface {
	Get(node g3.Node) bool
	N() int
}

type Space16

type Space16 interface {
	Space
	Set16(node g3.Node, v uint16)
	Get16(node g3.Node) uint16
	SetAllFilled(threshold, val uint16)
	MapBoundary(f func(node g3.Node))
	Volume() int64
}

type SparseVolume

type SparseVolume struct {
	LK     int
	Cubes  [][]uint16
	Colors []uint16
	// contains filtered or unexported fields
}

SparseVolume represents a voxel cube.

func NewSparseVolume

func NewSparseVolume(n int) (v *SparseVolume)

NewSparseVolume create a voxel cube with side n.

func (*SparseVolume) Get

func (v *SparseVolume) Get(node g3.Node) bool

Get returns true, if the voxel is filled (color != 0).

func (*SparseVolume) Get16

func (vol *SparseVolume) Get16(node g3.Node) uint16

Get16 returns the color of the voxel (empty voxel has color == 0).

func (*SparseVolume) MapBoundary

func (v *SparseVolume) MapBoundary(f func(node g3.Node))

MapBoundary invokes a provided function on every border voxel.

func (*SparseVolume) N

func (vol *SparseVolume) N() int

func (*SparseVolume) Set16

func (vol *SparseVolume) Set16(node g3.Node, val uint16)

Set sets the color of the voxel.

func (*SparseVolume) SetAllFilled

func (v *SparseVolume) SetAllFilled(threshold, val uint16)

SetAllFilled sets the specified color to all voxels with color >= threshold.

func (*SparseVolume) Volume

func (v *SparseVolume) Volume() (res int64)
