This adds mathematical lines to a scene. Their intersection with the current bounding box will be drawn.
abclines3d(x, y = NULL, z = NULL, a, b = NULL, c = NULL, ...)
Coordinates of points through which each line passes.
Coordinates of the direction vectors for the lines.
Draws the segment of a line that intersects the current bounding box of the scene using the parametrization (x, y, z) + (a, b, c) * s where s is a real number.
Any reasonable way of defining the
x, y, z and
a, b, c is acceptable.
See the function
A shape ID of the object is returned invisibly.
rgl.planes for mathematical planes.
segments3d draws sections of lines that
do not adapt to the bounding box.
