Abstract
Full-spectral color rendering capability of global illumination renderers
is still in need of improvement, particularly regarding performance,
which is a reason why many modelling programs for global illumination
are focused on three-component based color representation (e.g.
RGB). Full-spectral color representations are the basis for realistic
color appearance in realistic image synthesis. Currently, if compared
to common three-component rendering, the major disadvantage of fullspectral
rendering comes from higher computation costs because of
the greater amount of processed information. This thesis investigates
promising approaches of spectral color representation in the context
of a multi-level color rendering model called Spectral Mipmapping,
focused on the trade-off between time-efficiency and resulting image
quality in terms of perceived color difference. A test implementation
in a basic ray tracing renderer is used to evaluate results and make suggestions
concerning appropriate code design optimizations and spectral
sampling strategies. The influence of compiler optimization and
vector instruction use (based on SSE instructions) is discussed.
