float bezier(const float * t, const float * v, float time)

Calculates the value of a cubic Bezier function for t = time.

A cubic Bezier curve is represented by 4 points. Po is the start point, P1 and P2 are control points 1 and 2 and P3 is the end point. The start and end point denote the beginning and end points of the path and the control points determine how the path moves from the start to the finish. As can be seen from the image, the only variable changing is t which determines how far the path has progressed from P0 to P3. Cubic Bezier curves are used as timing functions particularly for keyframe interpolation.

Arguments

  • const float * t - Coordinates of the four points of the curve along the horizontal T (times) axis in the range [0.0f, 1.0f].
  • const float * v - Coordinates of the four points of the curve along the vertical V (values) axis in the range [0.0f, 1.0f].
  • float time - Time in the range [0, 1], for which the value of the Bezier function is to be calculated.

Return value

Value of the Bezier function.
