实体纹理特别适合许多建筑材料，因为它们本质上是3D的，如大理石和石头。直接将2D纹理应用于这样的材料会导致明显的伪影，因为合成实体材料或图案的问题通常非常困难。我们提出了简单而有效的固体合成，有效地利用程序纹理和基于范例的合成无缝地在一个系统。我们的方法产生扭曲的粒子，并将它们存储在基于细胞纹理的几个点上。体视学技术和弹簧系统用于自动引导合成过程。利用自适应k均值聚类，可以恢复具有高保真度的颜色样本。我们开发了矢量表示的结果，以避免模糊，和基于GPU的渲染实时合成一个共同的图形卡。实验结果表明，该方法可以在几秒钟内以低内存占用和高效的聚合材料合成生成真实的固体材料纹理。
Solid texturing is particularly well suited for many architectural materials as they are intrinsically 3D such as marbles and stones. Directly applying 2D texture to such material results in evident artifact because of the issue of synthesizing solid material or patterns usually very difficult. We propose the simple and effective solid synthesis that efficiently utilizes the procedural texture and exemplar-based synthesis seamlessly in one system. Our method generates warping particles and stores them with a few points based on cellular texture. Stereological technique and spring system are used to automatically guide the synthesis procedure. Using adaptive k-means clustering, we can recover color exemplar with high fidelity. We develop vector-represented results to avoid blurring, and GPU-based rendering for real-time synthesis on a common graphics card. Our experiments showed that the proposed approach can generate realistic texturing of solid material with low memory footprint and efficient aggregate-material synthesis in seconds.
