# arrow head

Posted on 2007-04-01

Hi,

I've asked this question a few times but still can't understand the answers. I need a really dumbed down answer.

I have two points in 3D space:

Point1: (x,y,z)

Point2: (x,y,z)

I want to draw an arrow from point1 to point2. At point2 I'd like to draw a pyramid cap to mimic an arrow head. So I need to know how to generate an additional 4 points that are equally distributed around point 2 - if I connect them all to point 2 it will look like a pyramid whose tip is point2.

Can someone please tell me how to fill this in then (the four generated base points of the pyramid arrow head):

base_pt_0 = (x,y,z);

base_pt_1 = (x,y,z);

base_pt_2 = (x,y,z);

base_pt_3 = (x,y,z);

If it is any easier - I could also draw a cone shape for the arrow head - i guess just like 16 points or so evenely distributed around point 2.

Thanks
