Create a CONE/FRUSTRUM in MATLAB || TUTORIAL

[@megancampbell3699]

Hi, I was wondering if you know how to make a cone which the peak is offset from the centroid with a similar method to which you have explained?

It is possible but making a video of with right now is impossible for me, so I will try to explain it here following what is done in the video for a normal cone: The cone is divided into a number of cross-sectional planes which are basically all circles of different radii, and they are arranged equally along the axis. Let's assume the axis is the X direction, and the circular cross sections lie on the Y and Z directions. And let's assume that the origin is at the base of the cone. This means that the offset will be in the Z or Y direction (or both!), and the process to achieve this is by translating each circular cross-section by a specific amount. In other words, adding a value to the Y or Z values for every cross section. So what you have to do, is create a vector of length [1, nCS] and each having the distance of this displacement for every cross section and then add it to Z or Y arrays.

Thanks, thats helpful! @@prot0form775

How to create a inclined cone upto x-y plane ? It generates ellipse on x-y plane. How to create function for that??

you can rotate anything using r-thet-phi coordinates
