I’m trying to render a surface using `QuadraticBezierCurve3`

which right now able to render a shape which lie on **same z coordinates** but when I try to change the position of z axis the curve won’t shift to that particular z axis.

Here, I’m rendering a surface using length of 3 array points which are alike

- 0: (4) [Array(3), Array(3), Array(3), Array(3)]
- 1: (4) [Array(3), Array(3), Array(3), Array(3)]
- 2: (4) [Array(3), Array(3), Array(3), Array(3)]
- 3: (4) [Array(3), Array(3), Array(3), Array(3)]

where I using 3 array of every array as [start, control , NUN, end]

the z index is not working,

Please provide the solution for that…
