Hi, I am a beginner in BRDF/Albedo research. And I need to draw a two dimensional plot revealing the relationship between "Bi-directional reflectance" and "view zenith/azimuth angle", just like a plot in the attached picture. Would anyone please tell me how to draw it, with a little bit of detail? Thank you so much!

Hi,
why not using gnuplot ? For example :
set parametric
set isosamples 30 , 30
Rx(u,v)=cos(u)*cos(v)
Ry(u,v)=sin(u)*cos(v)
Rz(u,v)=sin(v)
brdf(u,v)= .......
Brdfx(u,v)=brdf(u,v)*Rx(u,v)
Brdfy(u,v)=brdf(u,v)*Ry(u,v)
Brdfz(u,v)=brdf(u,v)*Rz(u,v)
splot [-pi:pi][0:pi/2] Brdfx(u,v),Brdfy(u,v),Brdfz(u,v)
