void Edit_Circular_Chord | ( | HC_KEY | key, | |
const HC_POINT * | point1, | |||
const HC_POINT * | point2, | |||
const HC_POINT * | point3 | |||
) |
Edits a circular chord as it sits in the database.
key | - key to a circle object. | |
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 chords are grouped with ellipses, polygons, shells and meshes for rendering purposes. The rendition of the interior of the chord can be adjusted with changes to Face Color and Face Pattern. The circumference of a chord 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.
