We have placed an update to the MegaScene1 distribution on myDIRSIG. The major aspect of this release is that it comes with a set of DIRSIG4 .scene files. This release also includes updates to material properties including the conversion of the tree leaf optical properties from extinction to transmission. We have found that changing this optical property provided speed ups because a large number of calls to the exponent function (to compute the transmission from the extinction) are eliminated.
Both updated scene files can be downloaded by registered users from the myDIRSIG website.
