NoiseBall3：一个Unity示例，显示如何使用DrawProcedural的新实现

NoiseBall3 ----------  This is an updated version of [NoiseBall2] that shows how to use `Graphics.DrawProcedural` to draw procedurally generated objects without giving any mesh data to the render pipeline. [NoiseBall2]: https://github.com/keijiro/NoiseBall2 Note that the `DrawProcedural` method was refurbished in Unity 2019.1 -- it's replaced with a new implementation, and the previous implementation was moved to a newly introduced method named `DrawProceduralNow`. So, now the following methods are available for procedural approaches. - `DrawProceduralNow` - Immediately executed without help of the render pipeline (i.e. no lighting/shadowing). - `DrawProcedural` - Executed via an intermediate renderer that supports the standard lighting/shadowing features. It can be said that `DrawProcedural` is the handiest way to draw procedural objects with enabling the standard lighting model and the post processing effects.
