Synthesizing Bark
Despite the high quality reached by today’s CG tree generators, there exists no realistic model for generating the appearance of bark: simple texture maps are generally used, showing obvious flaws if the tree is not entirely painted by an artist. Beyond modeling the appearance of bark, difficulty lies in adapting the bark features to the age of each branch, ensuring continuity between adjacent ...

متن کاملBark Resolution From
This paper discusses the relevance of non-uniform frequency resolution used by current speech analysis methods like Mel frequency analysis and perceptual linear predictive (PLP) analysis. It is shown that linear discriminant analysis of short-time Fourier spectrum of speech yields spectral basis functions which provide comparatively lower resolution to the high frequency region of spectrum. Thi...
متن کاملOak - Bark Tannins
1. The colorimetric method for estimation of acetoacetate by reaction with diazotizedp-nitroaniline has been adapted for measurements of oxaloacetate in amounts of 0 003-0 03 Htmole. 2. The steady-state level of oxaloacetate in the livers of normal and fasted rats was found to be about 4 umoles/100 g. dry wt. of tissue. The level was essentially unchanged in starvation when the level of acetoac...
متن کاملBark thickness and fire regime
1. Bark is a vital and very visible part of woody plants, yet only recently has bark characteristics started to be considered as key traits structuring communities and biomes. Bark thickness is very variable among woody plants, and I hypothesize that fire is a key factor selecting for a thick bark, and thus, at the global scale, a significant proportion of the variability in bark thickness is e...
