虽然测量的双向纹理函数（BTF）可以在材质外观上实现令人印象深刻的真实感，但它们提供的控制很少，这限制了它们在内容创建中的使用。在这项工作中，我们交互式地操纵BTF，并从平面纹理创建新的BTF。我们提出了一种核心外的方法来管理BTF的大小，并引入了新的编辑操作，修改材质的外观。这些工具实现其全部潜力时，通过使用新的选择算子选择性地应用于子集的BTF。我们进一步分析了使用我们的编辑操作符修改重要的视觉特性，如高光，粗糙度和模糊度。结果比较有利的直接改变的微观几何形状和反射率的合成参考数据。
While measured Bidirectional Texture Functions (BTF) enable impressive realism in material appearance, they offer little control, which limits their use for content creation. In this work, we interactively manipulate BTFs and create new BTFs from flat textures. We present an out-of-core approach to manage the size of BTFs and introduce new editing operations that modify the appearance of a material. These tools achieve their full potential when selectively applied to subsets of the BTF through the use of new selection operators. We further analyze the use of our editing operators for the modification of important visual characteristics such as highlights, roughness, and fuzziness. Results compare favorably to the direct alteration of micro-geometry and reflectances of synthetic reference data.
