POPULUS NIGRA LEAF:

Object name = PONIleaf0


NOTE: this leaf is larger than an actual leaf of the POPULUS NIGRA
species. To obtain a leaf with actual dimensions divide each x,y,z 
coordinate of a given triangle below by 13.1621. If you are using a
3D RT model capable of ingesting this leaf definition file (as well 
as the other tree and scene definition files provided on the RAMI 
short rotation forest description webpage) then proceed without 
changing anything. The scaling of the PONI leaf down to the correct 
leaf dimensions will be accounted for in the tree definition files 
PONI*foliage.dat later on.

The structural properties of the PONI leaf defined in this file is:

Total leaf surface (9 triangles) = 0.74159 m2
Maximum leaf length (inclusive twig) = 0.9 m
Maximum leaf width from vertical axis = 0.4854 m

Leaf lies in the ZY plane, X=0 for all vertices, bottom of twig lies at origin

Synthax for the various geometric primitives (sphere, cylinder and triangle):

sphere radius Xcenter Ycenter Zcenter
cylinder radius Xbottom Ybottom Zbottom Xtop Ytop Ztop
triangle Xvertex1 Yvertex1 Zvertex1 Xvertex2 Yvertex2 Zvertex2 Xvertex3 Yvertex3 Zvertex3

All x,y,z coordinates have units of meter [m]
