How to create TRIANGLE_FAN?

Hello,

- Use P3D
- First vertex is (0, 0, 0)
- Other vertices are about the circumference of a circle with a Z-offset.
- it was easier to work with origin at center of canvas:

`translate(width/2, height/2);`

You can orient the shape however you wish and change the co-ordinates.

beginShape(POINTS):

beginShape(TRIANGLE_FAN):

```
beginShape(POINTS);
vertex(0, 0, 0);
for(int i = 0; i<=420; i++)
{
//generate x and y about the circumference of a circle
vertex(x, y, 100);
}
endShape();
```
