[Radiance-general] Computing irradiances for glow materials

[Claus Brøndgaard Madsen]

Hi Lars,

I'm sorry. I don't understand what you mean by this. I am assuming that all materials are diffuse, but, as Thomas said, I wish to treat the image as a emitted radiance in an image-based illumination scheme, and I wish to compute the irradiance for every point in the scene under the condition that the backprojected HDR image is the only energy in the scene.

Best,
Claus

Just an idea... if you assume all materials to be lambertian, you just need the reflectance of any visible surface to be able to calculate the irradiance it receives...?

Cheers, Lars.
