We present a system for designing indoor scenes with convertible furniture layouts. Such layouts are useful for scenarios where an indoor scene has multiple purposes and requires layout conversion, such as merging multiple small furniture objects into a larger one or changing the locus of the furniture. We aim at planning the motion for the convertible layouts of a scene with the most efficient conversion process. To achieve this, our system first establishes object-level correspondences between the layout of a given source and that of a reference to compute a target layout, where the objects are re-arranged in the source layout with respect to the reference layout. After that, our system initializes the movement paths of objects between the source and target layouts based on various mechanical constraints. A joint space-time optimization is then performed to program a control stream of object translations, rotations, and stops, under which the movements of all objects are efficient and the potential object collisions are avoided. We demonstrate the effectiveness of our system through various design examples of multi-purpose, indoor scenes with convertible layouts.

可转换室内场景布局设计的运动规划。

我们提出了一个用于设计具有可转换家具布局的室内场景的系统。这种布局对于室内场景具有多种用途且需要布局转换的场景很有用，例如将多个小家具对象合并为一个较大的对象或改变家具的轨迹。我们旨在以最有效的转换过程为场景的可转换布局规划运动。为了实现这一点，我们的系统首先在给定源布局和参考布局之间建立对象级对应关系以计算目标布局，其中对象在源布局中相对于参考布局重新排列。之后，我们的系统根据各种机械约束初始化源布局和目标布局之间对象的移动路径。然后执行联合时空优化以对对象平移、旋转和停止的控制流进行编程，在此情况下，所有对象的运动都是有效的，并且避免了潜在的对象碰撞。我们通过具有可转换布局的多用途室内场景的各种设计示例来证明我们系统的有效性。
