format Unit32 count = MTH_Curve2t (MthCurveWork * work, MthXy * in_aray,
: Unit32 in_n, Unit32 out_n, MthXy * out_aray, MthXy * tan_aray)
Input work: Work area pointer
: in_aray: Input coordinate array
: in_n: Number of input coordinates
: out_n: Number of output coordinates
Output out_aray: Output coordinate array
tan_aray: Tangent vector of each output coordinate
Function value count: Number of output coordinates of 2 or more 0: Parameter error
Function work specifies the work area secured by the MTH_INIT_CURVE macro.
. in_aray specifies the input coordinate array pointer that passes the curve.
in_n specifies the number of in_arays. Specify a value of 3 or greater.
out_n specifies the number of out_arays. Specify a value of 2 or greater.
out_aray is a pointer that receives the calculation result. An array of output coordinates that pass through the curve
is returned .
In tan_aray, a tangent vector indicating the direction of travel at each output coordinate is returned. Contact
The size of line line vector is 1.0.
