Visual Simulation of Wood Weathering
نویسندگان
چکیده
The aging process of material is an unavoidable natural phenomenon. Thus, several CG techniques for representing aging phenomena, such as metal corrosion and stone weathering, have been studied. In this paper, we propose a visual simulation method of wood weathering. First, we present the wood model in consideration of branching. Then, we give the algorithm for representing the weathering of the color and shape of wood. Several simulation examples show the availability of the proposed method. Finally, we conclude this paper and mention the future work. キーワード: 木材,経年変化,侵食,ビジュアルシミュレーション, モデリング,ソリッドテクスチャ

Effect of Weathering on Wood Treated with Tall Oil Combined with Some Additives
Growing interest on bio-based material has led to focus on environmentally benign wood treatment systems because of the environmental concerns. Tall oil is a by-product from pulp and paper industry, contains resin and fatty acids, and is biodegradable. Tall oil treated wood can provide some reduction in water uptake and increase in decay resistance. In this research crude tall oil was dissolved...
متن کاملVisual Simulation of Weathering By γ-ton Tracing
Weathering modeling introduces blemishes such as dirt, rust, cracks and scratches to virtual scenery. In this paper we present a visual simulation technique that works well for a wide variety of weathering phenomena. Our technique, called γ-ton tracing, is based on a type of aging-inducing particles called γ-tons. Modeling a weathering effect with γ-ton tracing involves tracing a large number o...
متن کاملMonitoring Wood Degradation during Weathering by Cellulose Crystallinity
The degree of crystallinity of cellulose was used for assessing the degradation level of coated and uncoated samples of pine wood after weathering. X-ray diffraction (XRD) and Fourier Transform Infrared (FT-IR) spectroscopy measured the changes in the surface crystallinity of cellulose resulting from weathering, both natural and artificial. Both techniques revealed an increase in the crystallin...

متن کاملPerformance Characterization of Coatings on Treated-wood
Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...
