使用Inkscape制作高级贝塞尔曲线

Inkscape  is a free program that uses SVG (Scalable Vector Graphics) for its file format, and these SVG files can be imported into blender as Bezier curves. Inkscape has some great tools for making advanced shapes that would take forever to make in Blender itself. We will use Inkscape because it is free, and it is very easy to learn.

播放段落
• Mac OS X and Windows : Go to  Inkscape.org  and click download. there will be installation files for each operating system.
  ::进入Inkscape.org并点击下载. 每个操作系统都会有安装文件.
播放段落
• Linux : Go into the terminal.
  
  ::进入终端.

For Arch Linux, type  pacman -S inkscape
For Debian based distributions, type  sudo apt-get install inkscape
For Fedora and rpm based distributions, type  yum -y install inkscape
For any other distribution, check your package manager to see if it has a package for inkscape. if not, download the source code at  Inkscape.org  and run PKGBUILD in the directory of the source.
::对于Arch Linux,输入 pacman -S inkscape对于基于Debian的发行版,输入 sudo apt-get install inkscape对于基于Fedora和rpm的发行版,输入 yum -y install inkscape对于任何其他发行版,请检查您的包管理器是否有 inkscape 的包. 如果没有,请从Inkscape.org下载源代码,并在源目录中运行PKGBUILD.

Inkscape is a pretty large program, so it will take a while to download and install.
::这是一个相当大的程序,所以下载和安装需要一段时间.

Because blender doesn't import any effects or filters from SVG files, we will only have to learn basic path modeling. This is very easy to learn, and will take no time at all. Once it's finished installing, open Inkscape. You will see a large empty page and a bunch of buttons to the left. Don't mind the empty page, we won't be needing it. We will re-size this once we are done with the tutorial. Before we get started, I will show you how to use some of the controls. You will probably be right clicking a lot because you're used to blender, but that's okay. Let's start out with a star to practice some of the controls. Click the Star/Polygon tool to the left, and click anywhere on the paper and drag.
::由于混合器不从SVG文件中导入任何效果或过器,我们只需要学习基本的路径建模.这很容易学习,而且不会花费时间.一旦安装完成,打开Inkscape.您将看到一个大空页面和左边的一堆按.不要介意空页面,我们不需要它.我们将在完成教程后重新调整尺寸.在我们开始之前,我将向您展示如何使用一些控制.您可能会经常点击右键,因为您已经习惯了混合器,但没关系.让我们从一颗星开始练习一些控制.点击左边的星/多边形工具,然后点击纸上的任何地方并拖动.

go back to "Object Mode" by clicking the cursor icon to the left. Now, let's try out some of the controls:
::现在,让我们尝试一些控制:

These are only a few of the controls, you will learn more controls later in this tutorial.
::您将在本教程中学习更多的控制.

Go back to the Star/Polygon tool so we can edit the star. You will see 2 dots appear on the star. You can drag these around, and see what happens. Another thing you can do is add more points to the star, change the spike ratio, make it rounded, and make it randomized with the "CHANGE:" Dialog right above your image. 
::现在我们可以使用"星/多边形"工具来编辑星. 星上会出现两个点. 你可以拖动它们,看看会发生什么. 还有一件事是,你可以在星上添加更多点,改变尖峰比率,使其圆形,并通过"CHANGE:"对话框在图像上方随机进行.

If you want to edit each node separately without symmetry, go back to 'Select and Transform Objects' mode  and click Path>Object to Path. Now you can just go to 'Edit Paths by Nodes' mode  and play around with the shape a bit.
::如果您想单独编辑每个节点而没有对称性,请回到'选择和转换对象'模式,然后单击路径>对象到路径. 现在您可以进入'编辑节点路径'模式,并稍微玩弄形状.

By clicking and dragging, you can move a node or curve an edge. when you make a curve, 2 nodes will show up that you can drag and edit the curve with more precision.
::通过点击和拖动,你可以移动一个节点或曲边缘. 当你做一个曲线, 2节点会显示出你可以拖动和编辑曲线更精确.

To add a node in the path, select an edge and press the plus button   to remove a node, press the minus button, and, well, the buttons pretty much explain themselves, so you can just play around and see what you get.
::按下加号按去除一个节点,按下减号按, 按几乎可以自己解释,

After you think you know how to edit paths pretty well, let's try to make a path from scratch. Click the 'Draw Bezier Curves' button   and click to add nodes for the shape you want. If you click and drag, you will make a node and curve the node while dragging the mouse. To finish the path, go around to the first node that you made and click on it. This will finish the path and make it a solid shape. When it is done, a outline, or stroke of the shape will appear. If you want it to show as a solid shape, you can click one of the colors on the bottom and it will fill the path with that color.
::现在,我们可以尝试从头开始创建路径. 点击'画贝齐尔曲线'按,然后点击添加你想要的形状的节点.如果点击和拖动,你会在拖动鼠标时创建一个节点并曲线节点. 完成路径,转到你创建的第一个节点并点击它. 这将完成路径并使其成为一个固体形状. 当它完成时,将出现一个轮或图形的图形. 如果你希望它显示为一个固体形状,你可以点击底部的颜色之一,它将以该颜色填充路径.

Now, move the star inside the path (In 'Select and Transform Objects' mode, of course), without it overlapping the borders of the path. If the star is too big, scale it down and hold ctrl to keep the same scale on the X and Y axis. Select both your path and the star, and press Path>Difference to cut a star-shaped hole inside your path.
::现在,将星移到路径内 (当然在'选择和转换对象'模式下),不要让它重叠路径边界.如果星太大,缩小它,并按住ctrl以保持X和Y轴上的相同尺度.选择你的路径和星,然后按路径>差异,在你的路径内切割一个星形孔.

Congratulations, You have made a completely pointless random shape and learned the basics of creating a shape in inkscape! Now, It's time to get this into Blender! Save your SVG image, and open up blender. Press File>Import>Paths(.svg, .ps, .eps, .ai, gimp) (Blender 2.49). Select your SVG file and the settings are fine how they are. Press OK and see your path appear in blender (You may have to delete the default cube to see it) From here, you can Extrude, bevel, and do whatever you want to you bezier path in blender.
::恭喜你,你已经做了一个完全无用的随机形状,并且学会了在Inkscape中创建形状的基础!现在,是时候把这个带到Blender了!保存你的SVG图像,然后打开Blender.按文件>导入>路径 ().svg, .ps, .eps, .ai, gimp) (Blender 2.49).选择你的SVG文件,设置是好的.按OK,然后在Blender中看到你的路径 (你可能需要删除默认的立方体才能看到它) 从这里,你可以挤出,曲,以及你想要在Blender中做任何你想要的路径.

The result may look something like this: 
::结果可能看起来像这样:
