Detailed Description

Function Documentation

void DEdit_Circular_Chord ( HC_KEY  key,
const HC_DPOINT *  point1,
const HC_DPOINT *  point2,
const HC_DPOINT *  point3 
)

Similar to Edit_Circular_Chord(), but operates on double-precision data.

Parameters
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.
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.

Parameters
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.

DETAILS

The order of the specified points is important. Specifically, the chord begins at the first point, is drawn through the second point and continues through the third point. A line connects the first and third points. The chord is defined as the area bounded by the points.

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.
