PSurfacePosition

When used in combination with a PBorn node, this node provides an easy way to emit particles from an object’s surface. It calculates randomly selected positions on the points, edges or polygons of a polygon object. The polygon object may be deformed if you wish; the positions will still be calculated correctly.

当与 PBorn 节点结合使用时，该节点提供了从物体表面发射粒子的简单方法。它随机计算多边形对象的点、边或多边形上的选定位置。如果您愿意，多边形对象可能会变形; 位置仍然可以正确计算。
