CS348b Project Proposal
Andreas Edlund and Tim Chao
In our project, we intend to explore techniques in
realistically rendering surfaces with fine geometric structures
such as grass and fur.
To motivate this, we will try to render a realistic scene of a
teddy bear sitting in short grass in an outdoor scene.
We will use as reference Kajiya and Kay's paper, "Rendering fur with
three dimensional textures" in which texels are used to simulate the
reflection of light through fur. We hope to apply similar volumetric
techniques to our rendering of the grass, but the coarse nature of
grass may offer a different challenge. Reeves and Blau's "Approximate
and Probabilistic Algorithms for Shading and Rendering Structured
Particles" presents another method that might be explored in rendering
- Rendering with Three-Dimensional Textures: we will explore using
Kajiya and Kay's techniques of texel shading in lrt. This can be
applied towards our rendering of fur.
- Generating appropriate textures to simulate grass and fur.
- Realistic wind effects, applied to fur and grass.
- Use subsurface scattering to accurately render leaves in the grass.
- Try using actual geometry to model blades of grass.
