CS497 Advanced Graphics Rendering and Appearance Modeling
Instructor: Yizhou Yu
Spring 2003, TuTh 11:00am-12:15pm, 3211 DCL(TuTh), 57 Everitt
This course covers appearance modeling, photorealistic rendering,
nonphotorealistic rendering and image-based rendering.
These topics have been fascinating research directions in graphics.
Appearance modeling includes texture generation and synthesis, surface
reflectance and subsurface scattering modeling,
surface detail modeling such as bump/displacement maps,
bidirectional texture functions, effects due to erosion and weathering.
Graphics rendering techniques try to model the interaction between light
and object models to create synthetic images.
Object models include both geometry and appearance models.
Photorealistic rendering tries to simulate the lighting process
in the real world and generate synthetic images comparable to real photographs,
while nonphotorealistic (artistic) rendering tries to simulate various
artistic painting styles as well as provides visualization techniques to
convey the details in shape and surface attributes.
rendering algorithms include ray-tracing and radiosity. This course gives an
overview of these algorithms, but focuses on recent development on
Monte Carlo ray tracing, photon mapping, and natural scene rendering.
The part of the course on nonphotorealistic rendering covers recent techniques
on silhouette rendering, pen-and-ink illustration, painterly rendering,
watercolor simulation etc.
Image-based rendering covers panoramic masaicing, light field rendering etc.
Grading is based on MPs and class presentations. The specific allocation is
as follows: presentation 10%, MP1 40%, MP2 50%.
MP1 (due March 20, 2003): choose one of the following options:
i) implement reaction-diffusion textures;
ii) implement one of the 2D texture synthesis algorithms or design a new one;
iii) implement one of the algorithms for texture synthesis
on arbitrary 3D mesh objects or design your own algorithm;
iv) simulate wavelength dependent reflectance functions
considering amplitude splitting interference;
v) simulate reflectance functions considering subsurface scattering
in multiple layers.
If you choose either i) or ii), you should produce at least one example where
the synthesized textures are mapped onto a 3D polygonal or curved object.
This object could be a sphere. Note that it is not trivial to map a
rectangular texture onto a sphere.
If you choose either iv) or v), you should implement a simulator generating
reflectance functions, and also render at least one
curved object (more complicated than a sphere), illuminated with some
light sources, using your simulated reflectance functions.
You should be able to show demos of your program in class on March 20.
Also turn in a short report describing your implementation and design details
along with a small number of examples including related images produced
by your program.
Final Project (due May 6, 2003):
implement a system or perform preliminary research on a proposed topic in
i) appearance modeling; or
ii) photorealistic rendering; or
iii) nonphotorealistic rendering; or
iv) image-based rendering.
For system implementation, grading is based on the completeness and reliability
of the system and the quality of the generated images.
For research topics, grading is based on the novelty of the proposed technique
and the quality of the experimental results. Turn in a short report describing
your implementation and/or experimental details along with some examples.
Be prepared for a demo in class on May 6.
