#	Line 20 | Line 20 | genklemsamp - generate ray samples over surfaces using
20		generates ray origins and directions to sample planar surfaces
21		needed to determine incident radiances or daylight coefficients.
22		This command is typically used in conjunction with
23	<	.I rtcontrib(1)
23	>	.I rcontrib(1)
24		to analyze exterior daylight coefficients
25		for an annual simulation.
26		.PP
#	Line 55 | Line 55 | The
55		option specifies that output rays should be generated as 32-bit IEEE binary
56		float values.
57		This may be more efficient if passed directly to
58	<	.I rtcontrib
58	>	.I rcontrib
59		or
60		.I rtrace(1)
61		with the same option.
#	Line 68 | Line 68 | produces ASCII floating point values.

69		To generate 500 samples per direction over a set of south-facing windows and
