[Radiance-general] 答复: findglare problems

[Clarence Wang]

Hi Greg,

For #1, the command was conducted well when replacing a new hdr image (after "getinfo") which was revised according to your kind suggestion, but the following results (including the headers) did not get any information about the glare source. How could this be?

#?RADIANCE
findglare -r 800 -vf fisheye.vf -p fisheye1.hdr a.oct
VIEW= -vth -vp -2 -1 1.2 -vd 0 -1 0 -vu 0 0 1 -vh 180 -vv 180 -vo 0 -va 0 -vs 0 -vl 0
FORMAT=ascii

BEGIN glare source
END glare source
BEGIN indirect illuminance
0 2201.149026
END indirect illuminance

For #2, I will send you an attachment about the output of findglare.

Thanks,

Clarence

Hi lists,

I tried to use "findglare" and "glarendx" to obtain DGI value from a Radiance hdr image and was confused about the results.


  1.  When I conducted a command " findglare -r 800 -p fisheye.hdr -vf fisheye.vf a.oct > a.glr ", the terminal showed " cannot get view from picture "fisheye.hdr";
  2.  Though the other command " findglare -vf fisheye.vf -ga 10-180:10 -av .1 .1 .1 a.oct > a.glr " could result in desired values, such as the glare source and the indirect illuminance, the DGI values were "nan" when using the command " glarendx -t dgi a.glr".

Any suggestions to solve the problems like "cannot get view from picture" and the "nan" results?

The hdr image of 800*800 pixels was rendered by "rcontrib" , "pcomb" (containing skyglow and groundglow) and "falsecolor" .

Thanks,

Clarence
