Recall that a barycentric coordinate system is given with respect to a -dimensional simplex, where is no larger than the dimensional space. Given a set of scattered points, it’s possible to create a tessellation of the space by forming simplices from the points, such that any input point that lies within the convex hull of the scattered set can be expressed in terms of the enclosing simplex and its corresponding barycentric coordinates2. This can be understood as a kind of triangulated irregular network (TIN).

在深邃的海底世界，章鱼是当之无愧的“伪装大师”。当它游过珊瑚礁时，皮肤几乎在瞬间就能从米色变得灰褐，质感也从光滑变得粗糙，与周围岩石的纹理和色彩“完美融合”。人工材料能否像章鱼一样，拥有魔术般的“变装”能力？近日，《自然》杂志发表了美国斯坦福大学研究团队的一项新成果，受章鱼、乌贼等头足类动物启发，团队开发出一种新型聚合物材料，首次实现在单一器件上对表面视觉纹理和结构色彩的独立、动态调控。这项技术有望为动态伪装、自适应显示、智能建筑以及互动艺术等领域，提供全新的解决方案。
