本文介绍了为3D角色穿上衣服并对其进行操作的交互技术（以及底层实现）。用户在衣服上绘制自由形状的标记，并在3D角色上绘制相应的标记；然后，系统把衣服围在身上，使相应的标记匹配。在内部，该系统在身体表面围绕标记生长衣服，同时通过简单的放松步骤保持基本的布料约束。整个计算只需要几秒钟。之后，用户可以通过增强的拖拽操作来调整衣服的位置。与用户在3D空间中沿单一方向移动一组顶点的标准拖动不同，我们的拖动操作将布料沿着身体表面移动，从而实现更灵活的操作。用户可以在拖动过程中使用图钉固定某些布点。这些技术是在应用更复杂的布料模拟之前指定初始布料配置的理想方法。
This paper presents interaction techniques (and the underlying implementations) for putting clothes on a 3D character and manipulating them. The user paints freeform marks on the clothes and corresponding marks on the 3D character; the system then puts the clothes around the body so that corresponding marks match. Internally, the system grows the clothes on the body surface around the marks while maintaining basic cloth constraints via simple relaxation steps. The entire computation takes a few seconds. After that, the user can adjust the placement of the clothes by an enhanced dragging operation. Unlike standard dragging where the user moves a set of vertices in a single direction in 3D space, our dragging operation moves the cloth along the body surface to make possible more flexible operations. The user can apply pushpins to fix certain cloth points during dragging. The techniques are ideal for specifying an initial cloth configuration before applying a more sophisticated cloth simulation.
