Abstract:
This thesis proposes several new perceptually-motivated techniques to
synthesize, edit and enhance depiction of three-dimensional virtual scenes.
Finding algorithms that fit the perceptually economic middle ground between
artistic depiction and full physical simulation is the challenge taken in this
work.
First, we will present three interactive global illumination rendering
approaches that are inspired by perception to efficiently depict important
light transport.
Those methods have in common to compute global illumination in large and fully
dynamic scenes allowing for light, geometry, and material changes at
interactive or real-time rates.
Further, this thesis proposes a tool to edit reflections, that allows to bend
physical laws to match artistic goals by exploiting perception.
Finally, this work contributes a post-processing operator that depicts high
contrast scenes in the same way as artists do, by simulating it ``seen''
through a dynamic virtual human eye in real-time.
