Application for testing PBR shaders

Recommended Posts

Hello,

I'm currently implementing a PBR-based BRDF in my engine, and I'm having slight trouble/concerns about the correctness of my results. So I'd like to ask if someone knows of an application that can be used to check those kind of things - specifically, I'd like to see ie. how GGX/Microfacet-Distribution/... is supposed to look to check if I'm feeding it the right input values, so some kind of open-source code project where I can play around with the shaders would be exactly what I'm looking for. Is there any such thing? Thanks!

Thanks all for the suggestions!

I already knew Mitsuba and was planning on using it to evaluate my results. I didn't think it was useful for what I need right now, since right now I'm probably looking for some mistake in my shader code/data, so I was looking for something simpler; the two github-links look like they might work.
