数字媒体时代下交互式动画设计方法

动画格式与类型的不同,增加了交互式动画设计的难度,导致交互式动画设计效果不佳。本文提出数字媒体时代下交互式动画设计方法,根据模型的特点对三维空间的场景进行仿真建模,收集动画形态特征,以场景作为一个静态空间,利用坐标来描述节点。在此基础上,基于交互动画节点的变化性与移动性特征建立光滑函数,描述每个节点在虚拟空间的连接变化,实现数字媒体时代下交互式动画设计。实验结果表明,运用本文方法的人体动画与实际的人体动画位置基本保持一致,提高了交互式动画设计的效率以及交互的准确性,提升了交互动画的应用效果。

Characteristics of seasonal movement of hazel grouse(Bonasa bonasia) in a temperate forest

TThhiiss ssttuuddyy were carried out in the Experimental Forest (37 48?10?N, 127 48?50?E) of Gangwon Forest Development Institute, Gamjeong-ri, Chuncheon, Gangwon-do Province, Korea from Dec. 1999 to Jul. 2002. Eight individuals (three males and five females) of hazel grouse were captured and they were marked with a 14-g necklace-type transmitter. The surveying results showed that females were more active than males throughout the year, but males were more mobile than females in spring. The degree of movement for females and males was similar from summer to winter. The overlap degree of habitat was very large from spring to autumn. Hazel grouse had greater shifts in area use in winter. They used similar area from spring to autumn, made a shift in their habitat use in winter, and then shifted back to the previous habitat.
