Curved leaves #35

Adding a curvature of the leaves to improve realism

Jeroome commented 6 years ago

Question on this enhancement:

pradal commented 6 years ago

It depends on how the leaves are represented today. However, we have developped mesh simplification algorithms for leaves and studied the best compromise between accuracy and computation time:

With the curved leaves, modifications will have to be made to the calculation of the GAI

Emblanc commented 5 years ago

In the walter_leaf_mesh function, the argument "compensate" allows to compensate for area error. There are significant differences between the results of a simulation done with compensate = False and the same simulation done with compensate = True.

Here are the same graphs as previously but all with the same x-axis (in days) and from simulations that were made after the fix of issue #82 on negative surfaces.
