Edits a circular wedge as it sits in the database.
key | - Key to a circular wedge. |
point1 | - An x-y-z triplet for the coordinates of one of three ordered on the circumference of the circle.(A simple of three elements may also be used in most languages.) Passed by reference always. |
point2 | - As above. |
point3 | - As above. |
Circular wedges are grouped with ellipses, polygons, shells and meshes for rendering purposes. The rendition of the interior of the wedge can be adjusted with changes to Face Color and Face Pattern. The circumference of a wedge can be made distinct from the interior through the use of Edge Color, Edge Pattern and Edge Weight. A chord's Visibility and Selectability are controlled by the "edge", "face", and "polygon" keywords.
The order of the specified points is important. Specifically, the wedge begins at the first point, is drawn through the second point and continues through the third point. The center of a circle defined by the 3 points is computed. Lines are drawn from the first point to the center and from the third point to the center. The wedge is defined as the area bounded by the points.
