角色動畫往往是動畫影片中吸引觀眾目光的焦點。而隨著3D電腦動畫的日益普及,角色動畫的應用也日益廣泛。然而角色動畫中的虛擬人物動作模擬長久以來一直是電腦動畫裡最棘手的一個問題。看似基本的虛擬演員行進動控制,相關發表文獻便不下數十篇。本文的研究即在虛擬演員的步行動作控制,透過行進路徑的限制與虛擬演員的屬性規範,計算出“最佳化”的步行足跡,藉以驅動虛擬演員的行進動作。 足跡的運算主要依據有二:一為人類的步行研究,尤其是在遭遇障礙物時常用的策略;另一則是行進時最省力的能量消耗假設,也就是藉由量化的能量消耗評估公式來擇最佳化的足跡擺設。因兩者的研究並不侷限於平坦無障礙物的地面,加上以適應性的細節切割(Adaptive subdivision)來加最佳化行進軌跡的搜尋。因此不同於其他的步行研究,本研究更適於強調即時互動複雜場景裏虛擬演員的行進動作模擬。
Character animation is always one of the most attractive features in animation. Applications of character animation has grown rapidly. However, motion control of virtual character, up to date, still is a challenging task. This paper presents a motion control system dedicated to the animation of human figure locomotion in virtual environments. Optimized footprints planning, using locomotion attributes as the constraints, is used to control the virtual character’s locomotion. Footprints planning mainly based on the study of human walking, especially on uneven terrains, and minimal energy consuming during walk. Capability of walking on uneven terrains, and “adaptive subdivision” to accelerate the computation of motion trajectory. The system is well suited for character’s locomotion control in relatively complex virtual environment.
