oriendationExtractor.

返回一个功能的方向。基于输入几何类型,这将具有不同的可能返回值。请注意,方向将始终是下面未列出的任何几何形状的no_orientation。

区域

如果输入是适合右手或左侧规则的区域几何,则该属性将分别设置为right_hand_rule或left_hand_rule。该属性不会对退化区域具有有意义的值,例如具有图8边界的区域,或实际上是线或点的区域。

The right-hand rule requires that, on a walk of the area's coordinates, the area is on the right-hand side. Thus, outer boundaries must be clockwise and inner boundaries must be counterclockwise. The opposite is true for the left-hand rule.

表面

如果输入是曲面几何形状,那么曲面的所有部分都是一致的导向,该属性将被设置为Value_surface_orientation。如果部件是不知值或不一致的,则该属性将设置为Value No_orientation。

坚硬的

如果输入是一个立体几何,所有的地方normals point away from the interior of the solid, the attribute will be set to the value valid_solid_orientation. If all of the normals point towards the interior of the solid, the attribute will be set to the value reversed_solid_orientation. In all other cases, the attribute will be set to the value no_orientation.

观点

If the input is an oriented point geometry, the point’s orientation is extracted as a 3x3 matrix representation, and the attribute set as a list of the matrix values, in row-major order. Aggregates and multipoints only have point orientation extracted if they contain a single oriented point.

参数

编辑变压器参数

使用一组菜单选项,可以通过引用工作区中的其他元素来分配变压器参数。一些变压器也可提供更高级的功能,例如高级编辑器和算术编辑器。要访问这些选项的菜单,请单击除适用的参数旁边。有关更多信息,请参阅变压器参数菜单选项
