螺旋修改器

The Screw Modifier is similar to the Screw tool in the Tool Shelf in that it takes a profile object, a Mesh or a Curve, to create a helix-like shape.

Properly aligning the profile object is important.

外形应该恰当地对齐到物体的基向而不是螺旋轴。

选项

Screw Modifier.

轴向

沿其将建立螺旋轴。

螺旋
一次螺旋迭代器的高度。
Axis Object

用来定义轴向的物体的名字

物体螺旋
Use the distance from the Axis Object to define the height of one helix iteration.
角度
单个螺旋旋转的角度。
步进
Number of steps used for a single revolution displayed in the 3D View. Beware of setting this higher than Render Steps, which is the value used for rendering.
渲染步骤
跟上面一样,但是会在渲染期间使用。增加该值可以提升渲染质量。
平滑着色
采用光滑着色而不是平坦着色来输出面。输入几何形体的光滑、平坦着色不被保留。
Calculation Order
计算边的顺序,可以避免法线和着色的问题。仅网面需要计算,曲线不需要。
翻转
翻转法线方向。
迭代
迭代次数。
伸展UV
Stretch the UV coordinates from (0.0 to 1.0) when UVs are present.
Merge Vertices
Merge vertices that lie on the axis of rotation. Use this to close off end points with a triangle fan.
Merge Distance
Vertices under this distance to the axis are merged.
