装饰图案出现在许多艺术形式中,通常丰富了原本简单形状的视觉方面。这种图案特别难以创建,因为它们通常表现出复杂的结构细节,同时必须精确地匹配底层几何形状的大小和形状。在计算机图形学领域中,已经提出了几种方法来从示例中自动合成沿沿着的装饰图案。这使非专业用户能够使用简单的画笔隐喻,使他们能够轻松绘制复杂的结构化装饰。我们将这一想法扩展到设计和制造的空间。主要的挑战是正确地解释所产生的模式的拓扑结构。特别是,我们的技术确保合成的图案将由一个连接的组件组成,这样一旦打印出来,它们就形成了一个单一的对象。为了实现这一目标,我们提出了一个两步合成过程,首先合成的图案的拓扑结构,然后合成其精确的几何形状。我们引入拓扑描述符,有效地捕捉到目前为止合成的模式的拓扑结构。我们提出了几个应用程序,我们的方法,从设计对象使用合成图案沿着曲线和矩形内,装饰的表面与一个专用的平滑帧插值。使用我们的技术,设计师可以绘制结构化的图案,这些图案可以制作成坚实的有形物体,从示例中创建不寻常和令人惊讶的灯具,椅子和鞋带设计。
Decorative patterns are observed in many forms of art, typically enriching the visual aspect of otherwise simple shapes. Such patterns are especially difficult to create, as they often exhibit intricate structural details and at the same time have to precisely match the size and shape of the underlying geometry. In the field of Computer Graphics, several approaches have been proposed to automatically synthesize a decorative pattern along a curve, from an example. This empowers non expert users with a simple brush metaphor, allowing them to easily paint complex structured decorations. We extend this idea to the space of design and fabrication. The major challenge is to properly account for the topology of the produced patterns. In particular, our technique ensures that synthesized patterns will be made of exactly one connected component, so that once printed they form a single object. To achieve this goal we propose a two steps synthesis process, first synthesizing the topology of the pattern and later synthesizing its exact geometry. We introduce topology descriptors that efficiently capture the topology of the pattern synthesized so far. We propose several applications of our method, from designing objects using synthesized patterns along curves and within rectangles, to the decoration of surfaces with a dedicated smooth frame interpolation. Using our technique, designers paint structured patterns that can be fabricated into solid, tangible objects, creating unusual and surprising designs of lamps, chairs and laces from examples.
