npmcad-resample

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.steps (points, step)

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.along (points, size)

resample a curve at fixed size steps along it's own length.
