论文摘要
我们介绍了每半污染纹理（HTEX），一种对无明确参数化的任意多边形纹理的GPU友好方法。 HTEX建立在一个洞察力的基础上，即半身对多边形网格编码固有的三角剖分，每个半身边缘都跨越了一个独特的三角形，并具有直接的邻接信息。 HTEX并没有像以前的无参数纹理方法那样存储输入网格的单独纹理，而是为每个半edge及其双胞胎存储一个正方形纹理。我们表明，从脸部到半edge的这种简单变化诱导了高性能无参数化纹理的两个重要属性。首先，HTEX本地支持任意多边形，而不需要专用代码，例如非Quad Faces。其次，HTEX导致了一个直接有效的GPU实现，每半程仅使用三个纹理，以在整个网格中产生连续的纹理。我们通过实时渲染生产资产来证明HTEX的有效性。
We introduce per-halfedge texturing (Htex) a GPU-friendly method for texturing arbitrary polygon-meshes without an explicit parameterization. Htex builds upon the insight that halfedges encode an intrinsic triangulation for polygon meshes, where each halfedge spans a unique triangle with direct adjacency information. Rather than storing a separate texture per face of the input mesh as is done by previous parameterization-free texturing methods, Htex stores a square texture for each halfedge and its twin. We show that this simple change from face to halfedge induces two important properties for high performance parameterization-free texturing. First, Htex natively supports arbitrary polygons without requiring dedicated code for, e.g, non-quad faces. Second, Htex leads to a straightforward and efficient GPU implementation that uses only three texture-fetches per halfedge to produce continuous texturing across the entire mesh. We demonstrate the effectiveness of Htex by rendering production assets in real time.
