我们为艺术家提供基于外观的用户界面，以有效地设计定制的基于图像的照明环境。 1 我们的方法通过提供一组直观的用户界面来直接指定场景中模型所需的外观，从而避免了参数编辑、渲染和确认的典型迭代。然后系统通过解决逆阴影问题自动创建光照环境。为了获得逼真的图像，使用全频率照明和球面径向基函数 (SRBF) 表示。使用预计算辐射传输 (PRT) 执行渲染以实现响应速度。用户实验证明了所提出的系统与以前的方法相比的有效性。
We present an appearance-based user interface for artists to efficiently design customized image-based lighting environments. 1 Our approach avoids typical iterations of parameter editing, rendering, and confirmation by providing a set of intuitive user interfaces for directly specifying the desired appearance of the model in the scene. Then the system automatically creates the lighting environment by solving the inverse shading problem. To obtain a realistic image, all-frequency lighting is used with a spherical radial basis function (SRBF) representation. Rendering is performed using precomputed radiance transfer (PRT) to achieve a responsive speed. User experiments demonstrated the effectiveness of the proposed system compared to a previous approach.
