[Bf-vfx] HDRI (paper on capture techniques and more)

[eibriel inv]

If someone is interested on IBL on Blender, maybe must take a look to MedianCutQT ( http://nccastaff.bournemouth.ac.uk/jmacey/Pipeline/lighting.html ).
This software helps to convert a image on a Light probe. Using blender internal this is a really good solution. I've no tested it on Cycles yet.


You can see some tests I've made here:

about using HDRI, I would believe that SH would be very fast with the new compositor tile or as shader in Cycle.

Hi there,

>I ran into this paper which gives a very complete overview of different techniques for environmental lighting capturing, comparisons, ... for example it compares to use of mirror balls, fisheye stitched images or professional all-in-one equipments.
