Can someone p

Answer 1

I know it's an old question but I've been trying to solve similar problem so here is my solution for truncated cone:

public class Cone extends Group{

int rounds = 360;
int r1 = 100;
int r2 = 50;
int h = 100;

public Cone() {
    Group cone = new Group();
    PhongMaterial material = new PhongMaterial(Color.BLUE);

    float[] points = new float[rounds *12];
    float[] textCoords = {
            0.5f, 0,
            0, 1,
            1, 1
    };
    int[] faces = new int[rounds *12];

    for(int i= 0; i

Hope this helps someone in the future!
