void  njBezierSpline(float *idata, float *odata, NJS_SPLINE *attr, float frame);
float       *idata
float       *odata
NJS_SPLINE  *attr
float       frame

Arguments

idata
Input data (but idata[3*sample point number])
odata
Output data (but odata[3])
attr
Spline attribute
frame
Frame

Description

Bezier curve correction value is stored in the specified argument.
Please set the frame number to a value between 0 and 1.
For the attributes, please specify the sample point number
at the iparam member (attr->iparam[0]) of the spline attribute structure.

Usage Example

#include <NINJA.H> 
#define X1      1.f
#define Y1      0.f
#define Z1      0.f
#define X2      5.f
...........
#define  POINTS  5

float idata[3][5] = 
{
  {X1, Y1, Z1},
  {X2, Y2, Z2},
  {X3, Y3, Z3},
  {X4, Y4, Z4},
  {X5, Y5, Z5},
};
float odata[3];
NJS_SPLINE  attr;

...........
attr.iparam[0] = POINTS;
njBezierSpline((float*)idata, odata, &attr, 0.5f); 
...........
