Method Detail

gradient

public VJGradient gradient(OF3DFlow f,
                           VJVoxelLoc vl)

Compute an interpolated gradient from a flow vector volume. Normally in 3-D flow (scintillating streaks), the gradient at vl is the direction of the flow vector at vl. But if you need to render the static volume, you need to compute the gradient.

Parameters:

f - the flow volume.

vl - the VJVoxelLoc where to interpolate the gradient.

Returns:

a VJGradient with the interpolated gradient at vl.
