Tree crown shadow area and movement #13

Open shawking opened 5 years ago

shawking commented 5 years ago

Does the shadow that the crown make vary in area size, and does it move every hour? From looking at the source code it would seem to be no on both accounts. Is that correct?

Shadow of the tree is calculated in lightModule that is called not every day to same computing time. It is called more often in 2 cases 1) Tree growing season when leafArea increase more than a threshold 2) Sun declination is faster than a threshold The shadows is integrated for the all day but i think it takes into account the differents hours .... you should ask Christian to get more information on this point.
