Hi, i am new to paraview. I would like to visualise a zylinder in paraview. I already got the cartesian coordinates for the datapoints. Some cylinder differ in thickness and I like to plot a colorbar for the deviation of thickness for two different cylinders. What is the best datatype to import such cartesian coordinates? Which filters should I use? what else do I need, when i want to visualise the differenence in radius? Thanks for your help 🙂
