Abstract

Fur simulation is crucial in many graphic applications since it can greatly enhance the realistic visual effect of virtual objects, e.g. animal avatars. However, due to its high computational cost of massive fur strands processing and motion complexity, dynamic fur is regarded as a challenging task, especially on the mobile platforms with low computing power. In order to support real-time fur rendering in mobile applications, we propose a novel method called textured offset surfaces (TOS). In particular, the furry surface is represented by a set of offset surfaces, as shown in Figure 1(a). The offset surfaces are shifted outwards from the original mesh. Each offset surface is textured with scattering density (red rectangles in Figure 1(a)) to implicitly represent the fur geometry, whose value can be changed by texture warping to simulate the fur animation. In order to achieve high quality anisotropic illumination result, as shown in Figure 1(b), Kajiya/Banks lighting model is employed in the rendering phase.
在移动设备上使用纹理偏移表面的动态皮毛
皮毛模拟在许多图形应用中是至关重要的,因为它可以极大地增强虚拟对象的逼真视觉效果,例如动物化身。然而,由于大量皮毛处理的计算成本和运动复杂性,动态皮毛被认为是一项具有挑战性的任务,特别是在计算能力较低的移动平台上。为了支持移动应用中的实时渲染,我们提出了一种称为纹理偏移曲面(TOS)的新方法。其中,毛茸茸的表面由一组偏移面表示,如图1(a)所示。偏移曲面从原始网格向外移动。每个偏移表面都使用散射密度(图1(a)中的红色矩形)进行纹理处理,以隐式地表示毛皮几何形状,其值可以通过纹理翘曲来改变,以模拟毛皮动画。为了获得高质量的各向异性照明效果,如图1(b)所示,在渲染阶段采用Kajiya/Banks照明模型。
