[font=黑体][size=3]Introduction:
(简介）
--------------------------------------------------------------------------------
Before you do this tutorial you will need to know a couple of things. First of all you must have a good knowledge of the 3dsmax interface and tools. Second you have to be familiar the the standard animation and modelling tools in 3dsmax.
（在你学习这个教程之前，需要了解一些东西。首先，你要对3dsmax的界面和工具非常熟悉。其次，你需要了解3dsmax中标准的动画和建模工具。）
Also you have to have the bicycle model (downloadable on [/size][/font][url=http://www.lavitaz.com/][font=黑体][size=3][color=#2f5fa1]www.lavitaz.com[/color][/size][/font][/url][font=黑体][size=3]) and a 3D people model is nice to have but not nessesary.
（然后你需要有一个自行车的模型（可以在[/size][/font][url=http://www.lavitaz.com/][font=黑体][size=3][color=#2f5fa1]www.lavitaz.com[/color][/size][/font][/url][font=黑体][size=3]下载，已经一个3d人物模型，但这不是必须的。）[/size][/font]
[font=黑体][size=3]This tutorials has two parts. The first part is preparing the bicyle model. and the second one is adding a biped to the bicycle. [/size][/font]
[font=黑体][size=3]（这个教程包含两部分。第一部分是准备自行车的模型，第二部分是给自行车添加骨骼。）[/size][/font]
[font=黑体][size=3]Step 01 Preparing the bicycle model: [/size][/font]
[font=黑体][size=3]（步骤01 自行车模型的准备工作）
[/size][/font]
[font=黑体][size=3]--------------------------------------------------------------------------------
Start 3dsmax and load the bicycle.max file. As you can see this is a very basic bicycle but it will do. Begin by creating three circle spline’s. These splines will act as helper objects. &
（打开3dsmax并载入自行车的max文件。如你所见，这是一个非常基础的自行车模型。首先创建一个圆形的样条曲线。这下曲线作为帮助物体而使用。
Circle 01 and 02 have a radius of about 1.5 and are positioned at the center of the feet-pedestal.the third Circle have a radius of about 15 and is positioned at the center of the pedestal
（圆形01和圆形02半径为1.5，并被放置于脚踏板的地方。第3个圆形半径为15并被放置于基座的中心。）
For easy viewing I have converted Circle03 (the big red one) to a editable spline and removed one segment and made it renderable in the 3dsmax viewport.
（为了更容易分辨，我将圆形03（最大的红色的那个）转化为样条曲线，并移出了其中一段，并让它在视窗中可渲染。）

[font=黑体][size=3]Next what we are going to is to link server objects to each other. Look at the images below to see what object you need to link to what.
（接着我们要把相关的物体彼此链接起来。下图指示了我们需要链接的东西。）
Red arrow : black foot pedestals to the middle bar
（红色箭头：把黑色的脚踏板链接到中间的轴上。）[/size][/font]
[font=黑体][size=3]Blue arrow : middle bar to the helper object
（蓝色箭头：把中间的轴链接到圆形帮助物体上。）
[img]http://bbs.ew3d.cn/attachment/Fid_9/9_11_8b514a4d3038042.jpg[/img][/size][/font]
[font=黑体][size=3]Next link the helper object to the large circular helper object. Also link the main pedestal object to the large circle. Of course you have to repeat this to the other side of the bicycle ,[/size][/font]
[font=黑体][size=3]（接着把帮助物体链接到大的圆形帮助物体上。最后把基座链接到大的圆形帮助物体上。当然你需要对自行车另一侧进行相同的设置。）
Now all objects have been linked try rotation the large red circle. If you did all correct you will see the pedestals also are rotating. But as you can see the foot-pedestals are rotating also instead of being horizontal as they should be.
（现在所有的物体被链接到尝试旋转的大的红色圆形上。如果你正确处理了，你会看到基座也开始旋转了。但是你发现脚踏板也跟着旋转了，而不是保持应有水平状态。）
This can be fixed by selecting the green or small helper circle. Then goto the Utility panel > more > Link inheritance.
（这可以通过设置绿色的小帮助圆形来修正。进入工具面板》more》链接继承。）[/size][/font]
[font=黑体][size=3]Switch of the rotation x,y,z as you can see in the image
（如图，取消旋转x，y，z3个轴向的勾。）
[img]http://bbs.ew3d.cn/attachment/Fid_9/9_11_60d0d114bca828a.jpg[/img]
Now try rotating the red circle helper again. You will see the pedestals rotating correct. So that’s all the linking we need to do for now.[/size][/font]
[font=黑体][size=3]（现在再次旋转红色的圆形帮助物体，你将看到基座正确的发生了旋转。所有的链接现在设置完毕了。）[/size][/font]
[font=黑体][size=3]Step 02: Biped and finishing:
（步骤2：骨骼）
[/size][/font]
[font=黑体][size=3]--------------------------------------------------------------------------------
So now that we have the pedestals rotating the correct way two things remain to do, the biped and the wheels.
（现在基座的旋转已经正常，还剩下两个东西需要处理，骨骼和轮子。）
We are working on a script to automate the animation of the bicycle. But for now we are going to this the “easy” way. Select the tire of the wheels and link this to the spoke’s. so both get rotated.
（一般我们通过脚本来自动处理自行车的动画。但是这里我们使用更简单的方法。选择轮子的轮箍，把它链接到把手上，这样他们会一起旋转。）
Now select the spokes and go to the Motion tab> assign controller. Expand the Y rotation and press the button to change its controller type.
（现在选择把手，进入运动面板》指定控制器。展开到Y轴旋转控制上，改变它的控制器类型。）

[font=黑体][size=3]Select a waveform controller with the following settings:
（选择波形控制器，设置如下。）
[img]http://bbs.ew3d.cn/attachment/Fid_9/9_11_749a08ec6f245e1.jpg[/img]
Repeat this for both wheels. Check the direction of the rotation and if needed reverse the waveform by checking “Inverted”
（给另一个轮子进行相同的设置，检察旋转的方向，如果必要勾选“Inverted”进行反转。）[/size][/font]
[font=黑体][size=3]Create a biped, with a height of about 1.75cm. Position the biped in figure mode as seen on the image.[/size][/font]
[font=黑体][size=3]（创建一副骨架，高度为1.75cm。如下图所示放置骨骼。）
