#### Examples.

- Input:
  bezier(1,1+i,2+i,3-i,plot)
  Output:
- Input:
  bezier(point(0,0,0),point(1,1,0),point(0,1,1),plot)
  Output:

To get the parameterization of the curve, you can use the parameq command (see Section 13.13.8).

#### Examples.

- Input:
  parameq(bezier(1,1+i,2+i,3-i))
  Output:

  ⎛ ⎝ | 1−t | ⎞ ⎠ | 3+3 t | ⎛ ⎝ | 1−t | ⎞ ⎠ | 2 | ⎛ ⎝ | 1+i | ⎞ ⎠ | +3 t2 | ⎛ ⎝ | 1−t | ⎞ ⎠ | ⎛ ⎝ | 2+i | ⎞ ⎠ | +t3 | ⎛ ⎝ | 3−i | ⎞ ⎠

- Input:
  parameq(bezier(point([0,0,0]),point([1,1,0]),point([0,1,1])))
  Output:

  ⎡ ⎣ | 2 t | ⎛ ⎝ | 1−t | ⎞ ⎠ | ,2 t | ⎛ ⎝ | 1−t | ⎞ ⎠ | +t2,t2 | ⎤ ⎦
