Sketching reaction-diffusion texture

In this work, we present an interactive interface for sketching synthesized textures. Reaction-Diffusion (RD) is used as the basis for texture synthesis. RD allows an unlimited amount of non-repeating texture and offers great flexibility for mapping textures to arbitrary surfaces. However, it can be difficult to find starting values of parameters that will produce interesting patterns. We use machine learning to resolve the difficulty of determining appropriate initial values of the RD system. The system described here allows a user to sketch a pattern of spots or stripes with arbitrary orientations, and then automatically generates a pattern with the same attributes as the sketch. It also allows the user to interactively create more complex textures by adding another layer of pattern, as well as manipulate the color of the resulting texture. We also show that this procedure can be applied to realistic 3D surfaces.

在这项工作中，我们提出了一个用于绘制合成纹理的交互界面。反应 - 扩散（RD）被用作纹理合成的基础。RD允许生成无限量的非重复纹理，并为将纹理映射到任意表面提供了极大的灵活性。然而，很难找到能产生有趣图案的参数起始值。我们利用机器学习来解决确定RD系统合适初始值的困难。这里所描述的系统允许用户绘制具有任意方向的斑点或条纹图案，然后自动生成一个具有与所绘图案相同属性的图案。它还允许用户通过添加另一层图案来交互式地创建更复杂的纹理，以及操作生成的纹理的颜色。我们还表明，这个过程可以应用于真实的3D表面。
