파라미터
| center | The center of the circle. |
| normal | The normal of the circle. |
| from | The direction of the point on the circumference, relative to the center, where the sector begins. |
| angle | The angle of the sector, in degrees. |
| radius | The radius of the circle Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles. |
설명
Draw a circular sector (pie piece) in 3D space.
Solid Arc in the Scene View.
