Yup, thanks a lot! one more thing.
I tried to figure where the weave function is called. This brought me to 2
files - bundle.c and shoot.c. The documentation states that rt_shootray()
is the primary shot coordinator. I guessed that rt_shootray_bundle() (in
bundle.c) does the same, but for several rays (the per ray parallelization
you mentioned). Is this correct?
Best,
Param

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
