ImageDev

OrientedLinesImage3d

Creates a three-dimensional binary image containing a series of parallel oriented lines.

Access to parameter description

OrientedLinesImage3d creates a binary image with a set of parallel lines with a given orientation and separated by a given offset.
This module creates a binary image with oriented 3D lines. The orientation of these lines is defined by two angles: the polar angle $\phi$ (inclination from Z axis) and the azimuthal angle $\theta$ (orientation from X axis on the XY orthogonal projection).

Considering a plane that is orthogonal to this orientation, each line crosses this plane into a single point defining a rectangular grid regularly spaced and oriented by a third angle $\alpha$, as shown in Figure 2.
