subdivideCubic back to summary

subdivideCubic	back to summary
pack-priv static void subdivideCubic(final double[] src, final double[] left, final double[] right) Subdivides the cubic curve specified by the coordinates stored in the `src` array at indices `srcoff` through (`srcoff` + 7) and stores the resulting two subdivided curves into the two result arrays at the corresponding indices. Either or both of the `left` and `right` arrays may be `null` or a reference to the same array as the `src` array. Note that the last point in the first subdivided curve is the same as the first point in the second subdivided curve. Thus, it is possible to pass the same array for `left` and `right` and to use offsets, such as `rightoff` equals (`leftoff` + 6), in order to avoid allocating extra storage for this common point. Parameters src:double[] the array holding the coordinates for the source curve left:double[] the array for storing the coordinates for the first half of the subdivided curve right:double[] the array for storing the coordinates for the second half of the subdivided curve Since 1.7

pack-priv static void subdivideCubic(final double[] src, final double[] left, final double[] right)

Subdivides the cubic curve specified by the coordinates stored in the src array at indices srcoff through (srcoff + 7) and stores the resulting two subdivided curves into the two result arrays at the corresponding indices. Either or both of the left and right arrays may be null or a reference to the same array as the src array. Note that the last point in the first subdivided curve is the same as the first point in the second subdivided curve. Thus, it is possible to pass the same array for left and right and to use offsets, such as rightoff equals (leftoff + 6), in order to avoid allocating extra storage for this common point.

Parameters

src:double[]: the array holding the coordinates for the source curve
left:double[]: the array for storing the coordinates for the first half of the subdivided curve
right:double[]: the array for storing the coordinates for the second half of the subdivided curve
