HTML Application to draw and modify a NURBS Curve in 3D

NURBS Curve = Non Uniform Rational B-Spline Curve

Requirements:

1. Should enable the user to modify the x, y, z and h coordinates (homogeneous coordinates) of upto 20 control points constituting a NURBS Curve. The range for coordinates of the control points should be [-1,1]. The user should be able to modify these through sliders.
2. Should display the NURBS Curve on the screen in 3D, and this curve should change dynamically as the user modifies any of the values using sliders. Perspective View.
3. Should display the bounding box of dimension 2 units, centred at the origin.
4. Should enable the user to modify the camera angle (degrees), from which viewing is done.
5. Should enable the user to modify the u values of a chosen point, and should display a moving point on the curve as the user modifies this value using the sliders.
6. Should enable the user to view the Knot Vector.
7. All user input should be via sliders.
8. Should use WebGL, in the form of three.js.
