Bi-Scale Radiance Transfer real-time rendering of
global transport effects at both meso- and macro-
scales

RTT (Radiance Transfer Texture) mapped to a squared two different views (rows) 5 different lights (columns). At each texture point, the RTT produces exit radiance given an incident lighting vector and a view direction, to capture meso-scale effects.

(a) No PRT (b) PRT (c) Masking off (d) Masking on
Bi-Scale Rendering Effects. The rows are
different models in different lighting
environments. Columns (a) and (b) compare results
with/without macro-scale transport (PRT).
Columns (c) and (d) compare results using a
zoomed in view with/without view-dependence
(masking) in the RTT. Notice the pasted-on
look without masking.
