【】因为是广告卡通角色

*注 ：arnold（阿诺德）渲染器是渲染渲染在maya和XSI平台下的最新超级渲染器，其最大的广告特点就是物理算法，

2 – We then look up on the internet for a real life reference of what the hairdo could look like. This is only as a reference to capture certain real life details. Since we are going for a Cartoonish look, we are not aiming at reproducing the reference exactly. Of course a picture of a duckface girl is always a plus.
2 -然后我们在互联网上查找现实生活中的参考。以最后的渲染渲染美丽图片以接近2小时每帧的速度渲染,如果因为头发穿插而重新渲染就太糟糕了，我们现在有大约90 000股引导和它能上升到200000 
。广告当然女孩首先是制作要苗条。
1我们总是渲染渲染先从角色设计作为参考。因为是广告卡通角色 ，整个过程中外观是制作调整在一个快速的渲染场景。

6 – Once happy with the results, we copy the point clouds and emitters to the “render model” where the point clouds will be awaiting an Icecache for the corresponding shot. We use Alembic to transfer animation from rig to render model and the Ice emitters .
6 -一旦结果满意,我们复制点云和发射器的“渲染模式”,点云会等待一个Icec缓存。眉毛和胡子如果必要) 。广告都有3-16个角色。制作所有这些CG演员都需要发型的渲染渲染计算。然后从Nurbs获得模型物体。广告再使用syflex布模拟头发动力学 。制作所以也不能完全照搬 ，明亮的颜色有帮助看到发生了什么
。我们用Alembic传输动画到ice发射器。下面就是测试渲染。这些节点一般包括随机化和阻尼效果。添加一些位置的调整和ice节点来体现发型效果。计算速度快 ，

7 – Back to the Hair model we convert the guides strands to mesh geometries. We apply syflex cloth simulation operators to these geometries to get ready for shot simulation. We link the guide strands to the syflex mesh so they inherit the simulation.
7 -我们把头发引导转化成模型。就开始渲染一个单帧来看最终效果 。头发的PointClouds结算缓存会自动连接到缓存上 ，

10 – Once we are happy with the look of the hair, the movement of the simulation AND most of all once we’ve resolved all the problems, we give the signal to the rendering department. The hair PointClouds are always automatically linked to the appropriate simulation cache for the current shot so all they have to do is “unhide” the corresponding object in their scene and voila !
10 -一旦我们满意 ，

9 – Before we pass down the simulation caches to the rendering department, we need to do a test render to be sure every frame works and there is no glitch/pop. With final beauty renderings taking sometimes close to 2 hours per frame, it is not a good thing to have to re-render a shot because a hair strand is out of place ! The scene we use renders quickly with no complex shaders and only direct lighting.
9 -在缓存结算渲染之前，文章展示了这个短片的头发制作和渲染。设置简单 。目前被广泛的适用于电影渲染中，

5 – Then we repeat the process with the eyelashes and the eyebrows. During the whole process the look is tweaked in a fast rendering scene.

5 -然后我们重复这个过程
，这个想法是为了得到发型的形状和长度  。睫毛
、这就是Oceane Rabais和Bella Marinada的发型教程 。

4 – Next, we clone theses strands, add an offset to their position and apply a few Ice nodes to further the styling. These nodes generally include randomizing and clumping amongst others. We now have around 90 000 strands and it can go up to 200 000.
4,接下来,我们克隆这些引导，引导的精度很低从200 到400 ),所以很容易计算。最后即渲染啦不拉不拉 。得到睫毛和眉毛。
