# 曲线

## **概述**

曲线滤镜允许使用基于样条曲线的方式对地形高度进行精确定制。该滤镜将地形高度映射到一条曲线上，从而实现细致的调整。

## **参数**

<table><thead><tr><th width="179.699951171875">属性</th><th>描述</th></tr></thead><tbody><tr><td><strong>曲线</strong></td><td>构建一条将应用于地形的曲线。使用左键双击以添加新的控制点，右键单击某点以删除它。</td></tr><tr><td><strong>源范围</strong></td><td>设置从地形获取的最小和最大高度值。最小值对应图表上的0点，最大值对应图表上的1点。<br>通常，您会希望地形的最小值和最大值（显示在左侧高度计下方）落在您的源范围内。</td></tr><tr><td><strong>目标范围</strong></td><td>设置图表上0点和1点的输出高度。</td></tr></tbody></table>
