Several command line options are available to tune
Tachyon performance, display built-in help text, and
set output verbosity.
- -nobounding: disable automatic generation of hierarchical
grid-based acceleration data structures
- -boundthresh object_count: override default threshold for
subdividing grid cells with a new grid
- -numthreads thread_count: command line override for the number of
threads to spawn during the ray tracing process. When this
options is not specified, Tachyon determines the number of threads
to spawn based on the number of CPUs available on a given node.
- +V: enable verbose status messages, including reporting of
overall node and processor count.
- -nosave: disable saving of output images to disk files. This
feature is normally only used when benchmarking, or when using one of
the OpenGL-enabled Tachyon configurations which provide runtime display
of rendered images.
- -camfile filename: run a fly-through animation from
the named camera file.
