cperplines

Creates perpendicular lines to a set of points

The cperplines MATLAB function generates perpendicular lines to a set of 3D points. For each point in the input matrix main_points, it calculates a direction vector based on neighboring points, finds a perpendicular vector, optionally rotates it using a provided rotation matrix rot_mat, and creates two sub-points at a specified distance sub_point_distance from the main point along the perpendicular vector. The function returns a matrix perpendicular_points containing the endpoints of these perpendicular lines, useful for geometric modeling and visualization.
