The high energy diets that are typically fed to dairy cows can put the cow at risk of experiencing ruminal acidosis. High energy diets are low in neutral detergent fiber (NDF) and high in starch. The starch sources are often processed in a manner to optimize starch availability in the rumen and the fiber sources are often highly digestible and short in particle length. As a result, these types ...

We describe our recent work in applying physically-based global illumination to fiber tractography. The geometry of the fiber tracts is derived from diffusion tensor magnetic resonance imaging (DT-MRI) datasets acquired from the white matter in the human brain. Most visualization systems display such fiber tracts using local illumination, a rendering technology provided by the video card on a t...
