Get the 3D stack at timepoint index t.

Specified by:

getSource in interface Source<T extends net.imglib2.type.Type<T>>

Parameters:

Description copied from interface: Source

Get the 3D stack at timepoint index t, extended to infinity and interpolated.

Specified by:

getInterpolatedSource in interface Source<T extends net.imglib2.type.Type<T>>

Parameters:

t - timepoint index

level - mipmap level

method - interpolation method to use

Returns:

the extended and interpolated stack.

getMaskedSource

public net.imglib2.RandomAccessibleInterval<? extends net.imglib2.type.mask.Masked<T>> getMaskedSource(int t,
                                                                                                       int level)

Description copied from interface: Source

Get a Masked version of the 3D stack at timepoint index t.

By default, this is just Source.getSource(int, int) augmented with a constant mask 1.0.

Specified by:

getMaskedSource in interface Source<T extends net.imglib2.type.Type<T>>

Parameters:

t - timepoint index

level - mipmap level

Returns:

the masked stack

getInterpolatedMaskedSource

public net.imglib2.RealRandomAccessible<? extends net.imglib2.type.mask.Masked<T>> getInterpolatedMaskedSource(int t,
                                                                                                               int level,

Description copied from interface: Source

Get a Masked version of the 3D stack at timepoint index t, extended to infinity and interpolated.

By default, this is just Source.getInterpolatedSource(int, int, bdv.viewer.Interpolation) augmented with a constant mask 1.0.

However, most sources should override this to extend Source.getMaskedSource(int, int) to infinity (with a 0 mask) and interpolate.

Specified by:

getInterpolatedMaskedSource in interface Source<T extends net.imglib2.type.Type<T>>

Parameters:

t - timepoint index

level - mipmap level

method - interpolation method to use

Returns:

the extended and interpolated stack.

Description copied from interface: Source

Get the transform from the source at the given timepoint index and mipmap level into the global coordinate system.

Specified by:

getSourceTransform in interface Source<T extends net.imglib2.type.Type<T>>

Parameters:

t - timepoint index

transform - is set to the source-to-global transform, that transforms source coordinates into the global coordinates

getType

Description copied from interface: Source

Get the name of the source.

Specified by:

getName in interface Source<T extends net.imglib2.type.Type<T>>

Returns:

the name of the source.

getVoxelDimensions

public mpicbg.spim.data.sequence.VoxelDimensions getVoxelDimensions()

Description copied from interface: Source

Get voxel size and unit for this source. May return null.

Specified by:

getVoxelDimensions in interface Source<T extends net.imglib2.type.Type<T>>

Returns:

voxel size and unit or null.

getNumMipmapLevels

public int getNumMipmapLevels()

Specified by:

getNumMipmapLevels in interface Source<T extends net.imglib2.type.Type<T>>

doBoundingBoxCulling

public boolean doBoundingBoxCulling()

Description copied from interface: Source

Whether this source participates in bounding box culling.

If true, then this source will only be rendered if its bounding box, i.e., the interval of Source.getSource(int, int), intersects the current screen area (when transformed to viewer coordinates).

If false, then this source will be always rendered (if it is set to be visible.)

Specified by:

doBoundingBoxCulling in interface Source<T extends net.imglib2.type.Type<T>>

Returns:

true, if this source participates in bounding box culling.
