gen matrix surface-surface
gen matrix surface-surface [-h] [-v] <sender_surface> <receiver_surface> \
<model files...> [options]
gen matrix surface-surface generate a matrix between two arbiturary surface[s].
This command can be used, for example, to generate a matrix describes the
flux transport behavior of a tublar daylighting device.
Options
-b/--basis- Sender and receiver sampling basis (default: (kf, kf))
-f/--offset- Offset the sender and receiver surface in their normal directions (default: (0, 0))
All rtrace options are recognized as well.
Example
Generate a surface to surface matrix (e.g., for a tubular daylighting device)
