Hello, so i’m a new trainee and for my company i’m studying vtk in order to replace their 3D component, and for that reason i need to display boreholes as polylines, but the fact is that they want me to color each section of a polyline by a different color, is there any method native in vtk to do this? Or am i forced to split each polyline into multiple lines to color each one separately ? Thanks for any answer or advice that could helpme! ---

Use line cells instead of polylines cell. ---
