this is a plain c testbed for global illumination research code, which has been used for our projects at the computer graphics group at KIT (https://cg.ivd.kit.edu).

corona-13 follows a compile-your-own build strategy. rather than allowing a lot of run-time options, most of the flexible modules are fixed at compile time.
you can edit these settings in the file config.mk:
$ cp config.mk.example config.mk $ cp arch.example arch
and pick the modules you like best. also have a look at the file arch to suit your hardware.
$ make
mpeg stream rendering:
corona features a render server interface through corona-net, built with MOD_display=network. to use this, start corona as usual on the server. corona will block and wait for a client connection. you can initiate one by typing
$ make corona-netrender -C tools/
$ tools/corona-netrender
client side. maybe you need to tunnel it through a firewall by using ssh before launching corona-netrender:
$ ssh -f hostname -L 8090:hostname:8090 -N
enjoy!
