HC_KEY Insert_Circular_Chord | ( | const HC_POINT * | point1, | |
const HC_POINT * | point2, | |||
const HC_POINT * | point3 | |||
) |
Generates a polygon describing a portion of a circle.
point1 | - An x-y-z triplet for the coordinates of one of three ordered points on the circumference of the circle. A simple array of three elements may also be used for each parameter. 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.
You must make sure that the supplied points are not colinear. The system will issue an error message if all three points lie on a line, or if two points are coincident.

) |
Similar to Insert_Circular_Chord(), but accepts parameters of type double for increased precision.
point1 | - An x-y-z triplet for the coordinates of one of three ordered points on the circumference of the circle. A simple array of three elements may also be used for each parameter. Passed by reference always. | |
point2 | - As above. | |
point3 | - As above. |
