I have attached my latest effort to model Drury Tree's bark surface in X,Y,Z cartesian coordinates. This shape table has 2595 points and represents a partial map of the first 30 feet of trunk. You can rotate the overhead 2D and sideview 3D graph of the trunk by using the spinner arrows on the side or finer tuned slider arrows on the top.
As you can see from the overhead view, Drury Tree is enormous ! Looks to be 18ft diameter at 20ft off the ground. This is largest of any known redwood. When I get to 100ft off the ground and about 10,000 data points I will solve for volume using the theory of "homothetic slices" and update the forum with a more complete rotating graph of the massive lower bole of Drury Tree.
I think this tree will easily reach 35,000 cubic feet in trunk volume.
