take a line (an array of vertices) and return a resampled at fixed steps along the line or an axis.
The grey curve is generated with cardinal-spline-js,
the blue lines point to output of resample.steps and the green shows a resample.along line.
resample a curve at even steps perpendicular to a vector.
step should be a csg Vector3D instance.
points should be an array of Vector3D points, that define a curve you want to resample.
The curve must not have more than one intersection on any plane perpendicular to a line
through the first point in the direction of step. That is, if points is a mountain
range and step points along the foot of the mountians (along the horizon) then
the mountains can have steep cliffs but not fully vertical or caves or overhangs.
resample a curve at fixed size steps along it's own length.
