Function Documentation

void Insert_Circular_Chord ( const HC_POINT *  point1,
const HC_POINT *  point2,
const HC_POINT *  point3 
)

Generates a polygon describing a portion of a circle.

Parameters:
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

A portion of a circle is added to the current segment. 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.

NOTES

If you only work in two dimensions, specify all the z coordinates as zero. The system will automatically take note.

You must make sure that the points are not colinear. The system checks and issues an error message if all three points lie on a line, or if two points are coincident.

If there is an error the KInsert routine will return a-1.

HC_KEY KInsert_Circular_Chord ( const HC_POINT *  point1,
const HC_POINT *  point2,
const HC_POINT *  point3 
)

Similar to Insert_Circular_Chord(), but returns an HC_KEY to the object.

Parameters:
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.
Returns:
key

void QInsert_Circular_Chord ( const char *  segment,
const HC_POINT *  point1,
const HC_POINT *  point2,
const HC_POINT *  point3 
)

Similar to Insert_Circular_Chord(), but operates on a given segment rather than the currently open one.

Parameters:
segment - Segment(s) to be inserted into, if other than the currently- open segment.
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.

HC_KEY QKInsert_Circular_Chord ( const char *  segment,
const HC_POINT *  point1,
const HC_POINT *  point2,
const HC_POINT *  point3 
)

Similar to Insert_Circular_Chord(), but operates on a given segment and returns an HC_KEY to the object.

Parameters:
segment - Segment(s) to be inserted into, if other than the currently- open segment.
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.
Returns:
key

void DInsert_Circular_Chord ( const HCD_POINT *  point1,
const HCD_POINT *  point2,
const HCD_POINT *  point3 
)

Similar to Insert_Circular_Chord() but accepts and/or returns double-precision values. This command can only be used when the application source includes the HOOPS double-precision header, hcd.h.

Parameters:
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

No additional details. See Insert_Circular_Chord().

HC_KEY DKInsert_Circular_Chord ( const HCD_POINT *  point1,
const HCD_POINT *  point2,
const HCD_POINT *  point3 
)

Similar to DInsert_Circular_Chord(), but returns an HC_KEY to the object.

Parameters:
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.
Returns:
key

const HCD_POINT *  point1,
const HCD_POINT *  point2,
const HCD_POINT *  point3 
)

point2 - As above.
point3 - As above.
