摘要： A method and system for implementing capturing and rendering geometric details for mesostructure surfaces is described herein. A mesostructure distance function is defined as a function of a given reference point and a given viewing direction. A distance from a reference point to a mesostructure surface point along a viewing direction is measured using the mesostructure distance function. This distance is used to determine the visibility of mesostructure surface for rendering silhouettes. The lighting visibility of the mesostructure surface point may also be determined and used for determining whether the mesostructure surface point is in shadow. This determination may then be used for rendering shadow silhouettes.

摘要： A “mesostructure renderer” uses pre-computed multi-dimensional “generalized displacement maps” (GDM) to provide real-time rendering of general non-height-field mesostructures on both open and closed surfaces of arbitrary geometry. In general, the GDM represents the distance to solid mesostructure along any ray cast from any point within a volumetric sample. Given the pre-computed GDM, the mesostructure renderer then computes mesostructure visibility jointly in object space and texture space, thereby enabling both control of texture distortion and efficient computation of texture coordinates and shadowing. Further, in one embodiment, the mesostructure renderer uses the GDM to render mesostructures with either local or global illumination as a per-pixel process using conventional computer graphics hardware to accelerate the real-time rendering of the mesostructures. Further acceleration of mesostructure rendering is achieved in another embodiment by automatically reducing the number of triangles in the rendering pipeline according to a user-specified threshold for acceptable texture distortion.
摘要翻译： “mesostructure渲染器”使用预先计算的多维“广义位移图”（GDM），以便在任意几何的开放和闭合表面上提供一般非高度场介观结构的实时渲染。一般来说，GDM表示沿着体积样品内的任何点的任何射线投射到固体介观结构的距离。给定预先计算的GDM，然后，介观结构渲染器在对象空间和纹理空间中联合计算介观结构可见度，从而实现纹理失真的控制和纹理坐标和阴影的有效计算。此外，在一个实施例中，使用传统计算机图形硬件的介面结构渲染器使用GDM来渲染具有局部或全局照明的介观结构作为每像素处理，以加速介观结构的实时渲染。在另一个实施例中，通过根据用户指定的可接受纹理失真的阈值自动减少渲染流水线中的三角形数量来实现进一步加速的介观结构渲染。
