gen glaze

gen glaze [-h] [-v] <command> [options]
gen glaze command can be used to generate a Radiance material definition from either a IGSDB JSON file or an LBNL Optics file. glaze can be used to generate a single or a double-pane glazing system.

Options

-x/--optics
LBNL Optics file path[s]. Either optics files or IGSDB files (see below) is required.
-d/--igsdb
IGSDB JSON file path[s]. Either optics files (see above) or IGSDB files are required.
-c/--cspace:

Color space (color primaries) (default: radiance)

-s/--observer:

CIE Observer 2° or 10° (default: 2)

Example

Generate a single-pane system using a IGSDB JSON file: 

gen glaze -d igsdb_product_23000.json
    void BRTDfunc VNE-63_on_Pure_Mid_Iron
    10
        sr_clear_r sr_clear_g sr_clear_b 
        st_clear_r st_clear_g st_clear_b

To generate a double-pane glazing system using two JSON files downloaded from IGSDB, using the default color primaries and CIE observer, 
gen glaze -d 82378.json 43203.json
    void BRTDfunc VNE-63_on_Pure_Mid_Iron+VE-2M_on_Pure_Mid_Iron

        if(Rdot,cr(fr(0.035),ft(0.662),fr(0.043)),cr(fr(0.070),ft(0.593),fr(0.041)))
