Personally, I’d use non-sequential ray tracing.
First, I’d make the assumption that the surface / object was completely Lambertian and 100% reflective. While I’ve wanted to use BSDF (link) data, none of my clients have cared enough to get their materials measured.
I’ve always wanted to build a DIY BSDF measurement tool. Seems pretty straight forward. However, I’ve never had the time. Want to collaborate on this?
