     3 .SH NAME

     4 dayfact - compute illuminance and daylight factor on workplane

     5 .SH SYNOPSIS

     6 .B dayfact

     7 [

     8 falsecolor options

    10 .SH DESCRIPTION

    11 .I Dayfact

    12 is an interactive script for computing workplane illuminance,

    13 and daylight factors and potential daylight savings using

    14 .I rtrace(1).

    15 The script

    16 .I falsecolor(1)

    17 is then used to draw contour lines on the resulting Radiance
