Planet explosion

在3D Max中创建星球爆炸[教程] - 石像鬼 - 鬼喊鬼叫

Hi my name is Laurent Renaud, you may visit me also at my website at。

作者网站: http://laurent.renaud.free.fr  译者:邹超为

In this tutorial we will use particle flow and some max script tools to animate a planet explosion, or fragmentation.

这篇教程,我们将用到max脚本工具来实现星球爆炸动画以及碎片效果。

No max script knowledge is required and I will try to walk through most of the basic commands in Particle Flow. We will be using 3D Studio Max 2010.

没有max脚本基础也没关系。只需要一点基本的命令在粒子环节上。我将会用到max 2010。

Step 01 – Creating out planet

创建星球

First we will create the base model to work with. Create a GeoSphere. Set segments to 9. The actual size of this sphere does not matter since what we are doing is not physically based.

(看图即可,关键步骤我会翻译一下)

 

Step 03 – Get the script

下载一个脚本

We need a max script tool to fragment the model. It s free and very easy to use. Go to www.scriptspot.com and search for “fracture voronoi” or Click on the following link to download the script : - fracture voronoi maxscript -. This is a free tool done by Garp. Download the script in your 3dsmax script folder.  

到 www.scriptspot.com 网站上搜索"fracture voronoi”或者直接点击

- fracture voronoi maxscript - 下载这个脚本。

Step 04 – Back to Max

回到max

Go to the menu MAXScript/Run script and choose Fracture voronoi. A new window appear in the viewport representing the script. Click on Pick Object button and pick the Geosphere. Set the Nb Parts to 30, the iterations to 2 and check Uniform for the fragments color. Nb is the amount of fragements you can expect from the selected mesh, and we are setting the color to uniform to keep the wire color the same in the viewport.

到MAXScript/Run菜单,选择 Fracture voronoi脚本。新窗口会出现在视窗上。点Pick Object按钮选择球体。设置如图。

在3D Max中创建星球爆炸[教程] - 石像鬼 - 鬼喊鬼叫This tutorial is suggesting a fragment setting of 900, but if you have a old or slower PC adjust the Nb parts and iterations to give your computer a break. 

我建议将碎片fragment设置成900,但是你电脑很慢的话可以低一点。

Click on the Break button. Your base model has been hidden by the script. You can see the 900 fragments of the planet in the viewport. 点击Break,你的模型就被打碎了。

The script also created a new layer for you with all of your fragmented objects already added to good file management. 在3D Max中创建星球爆炸[教程][转载翻译] - 石像鬼 - 鬼喊鬼叫 

同时脚本会自动的为碎片创建一个层,方便管理。

 

Step 05 – Renaming the objects

为这些碎片命名。(用Max中的Tools/Rename命令)

Select all the fragments and go to the menu Tools/Rename objects … Set the base name to “Fragment” and hit the Numbered checkbox. This will auto-rename all of your objects with the base name followed by the incrementing number.

Click Rename, and then select all fragments and hide them. You may also go to your layer manager and hide this newly created layer. 

点击Rename,然后选择所有碎片,隐藏他们。你也可以去层管理器中将他们隐藏。

Step 6 – Lets dive into this particle flow

进入粒子环节

Hit 6 to open the Particle View. Here we will work to create the planet explosion. There is quite a bit in Particle View so it is easy to get overwhelmed, and it is just as easy to have a bit of fun with it. For the first time though please follow along, but if you are bold you can play with your own settings to see what you can come up with.

按数字键6进入粒子窗口。

Right-Click in the view and create a New/ Particle system /Standard flow.

在窗口中单击右键创建新粒子New/ Particle system /Standard flow

Delete every operators but the Display 01.

删除每一个Operators,除了Display01.

Pick a Birth Script operator in the depot and drag it in the Event 01 floater. Drag the Display 01 operator in the PF Source 01 floater and set Type to Geometry.

在Depot库中选取Birth Script Operator,将其拉到Event 01模块中。将Display01 operator拉到PF Source模块中,并将类型设置成Geometry. 

在3D Max中创建星球爆炸[教程] - 石像鬼 - 鬼喊鬼叫

 

Step 07 – Copy in the custom script

拷贝脚本

Select the Birth Script 01 operator and click on the Edit Script button. Select all existing script and delete it. Copy and paste the following one. *Note if you happen to click the green icon on the Birth Script, and it goes gray, don’t fret. This is turning on and off the event. Simple click it again and the event will then be active in the viewport.

选择 Birth Script 01 operator点击Edit Script button。选择上面已有的脚本先删除掉。拷贝我写的脚本。

on ChannelsUsed pCont do

(

pCont.useAge = true

pCont.useTM = true

pCont.useShape = true

)

on Init pCont do

(

global ChunksArray = $Fragment* as array

)

on Proceed pCont do

(

t = pCont.getTimeStart() as float

if t < 0 do

(

NumChunks = ChunksArray.count

for i = 1 to NumChunks do

(

pCont.AddParticle()

pCont.particleIndex = pCont.NumParticles()

pCont.particleAge = 0

pCont.particleTM = ChunksArray[i].transform

pCont.particleShape = ChunksArray[i].mesh

)

)

)

on Release pCont do

(

)

Close the Script window. You have now a particle system version of your fragmented planet. Your 3ds Max scene contain :

关闭Script窗口,你场景中的碎片现在已经有了一个新的粒子系统。你现在的场景中包含了以下物体:
- the base Geosphere model (hidden)

- the 900 fragments geometries (hidden on a new layer)
- the Particle Flow source replica of the fragments

 

Step 08 – Lets chuck some asteroids at it.

让我们弄些小侵略者

We will now create some 3 deflectors to hit the planet. Go to Create tab/Space Warps/Deflectors/SDeflector. Click and drag in the viewport to create 3 spherical deflectors.

我们现在将创建3个Deflector撞击星球。到创建面板选择 Space Warps/Deflectors/SDeflector。拉出3个球型Deflector到场景中。

Step 09 – Animating the Deflectors  为Deflector

加入动画

Animate the deflectors so they hit the planet one by one. Make the last one bigger to break the whole planet. You will be able to adjust the deflectors animation later. Below I have turned on Trajectory by right-clicking the deflectors and checking the trajectory box. 

为Deflector加入动画,让他们一个个的撞击。让最后一个大的撞碎整个星球。

在3D Max中创建星球爆炸[教程] - 石像鬼 - 鬼喊鬼叫

To animate these the quick and easy way is to drag your frame slider over to frame 100, turn on auto-key. Then make sure you have the move tool selected and move the deflectors to their desired location. Then to offset their timing on hitting the planet, you can drag the deflector 2 keyframe to start on frame 20, and then the third deflector to start on frame 40, etc.. This part of the tutorial is not meant to be followed exactly, so have some freedom here. 如图,这个步骤不是最关键的就不翻译了。

Step 10 – Lets make objects know they are there to hit each other.

让物体互相有碰撞

Hit 6 to show the Particle View. Pick a Collision operator in the depot and drag it in the Event 01 floater.

Select the Collision operator and click on the By list button to add the 3 deflectors.

Now, if you play the animation, the fragments are pushed forward when hit by the deflectors. The particles animation is directed by the deflectors settings. The particles bounce on it. We will correct this weird effect by using a new Event in the Particle View.

按6打开粒子面板。在depot库中选择一个Collision operator拉到Event 01模块上。选择Collision operator,点击By list按钮加入三个Deflector.

现在如果你播放动画,碎片已经会被Deflector所影响。现在要做的是让Deflector的影响看起来更真实。这就需要一个新的Event。

Step 11 – Adding speed and variation to the fragments

为碎片加入一些速度和其他变量

Pick a Speed operator in the depot and drag it beside the Event 01 floater.

 在Depot库中选择Speed operator。拉到Event 01 模块旁边。

A new Event 02 floater is created. delete the Event 02 Display operator and add a Spin operator from the depot.

To connect the 2 Events, Drag from the event output on the Collision operator  in Event 01 to the Event 02 input, and then release the mouse button.

新的Event02 模块创建好了,删除event 01中的Display operator,添加一个Spin Operator。连接两个Events,拉Collision operator的Event output到Event 02上,然后松开鼠标。

Set the Speed settings to Speed=20; Variation=19,Direction=Icon Center Out; Divergence=90., and the Spin settings to Spin rate=80;Variation=75.

设置属性如上。

Now, the deflectors settings don’t affect the particle animation. They just enable a new event with its own animation operators. You can adjust the Deflectors animation and watch the result in real time.

现在,Deflector设置并没有对粒子动画产生影响。只是开启了一个新的Event以及他们自己的动画设置。你可以播放看看。

Step 12 – Tweaking the animation and adding secondary fragments. 

调整动画,加入次级碎片

The animation is fine now. But we can do better by adding more details. We will spawn little particles from the existing ones.

动画看起来不错了,但是我们最好加入更多的细节。我们将在现有的基础上加入更多的小粒子。

Pick a Spawn operator in the depot and drag it at the top of the Event 02 operators.

在库中选择Spawn operator,拉到Event 02 operator上方。

Pick a Shape Instance operator in the depot and drag it beside the Event 02 floater.

再选择一个Shape Instance operator,拉到Event 02模块旁边。

A new Event 03 floater is created.

新的事件Event 03被创建好了。

Delete the Event 03 Display operator and add a Spin operator  and a Speed operator from the depot. Unhide a fragment geometry.

删除Even 03的Display operator,加入一个Spin operator和一个Speed operator。把所有碎片显示出来。

Select the Shape Instance operator in the Event 03, Click on the Particle Geometry Object and hit H to pick the fragment.

在Event03中选择Shape Instance operator,点击Particle Geometry Object,按H键选择碎片。

In the Shape Instance operator, set the Scale settings to Sale=25;Variation=100.

在Shape Instance operator中,设置Sale=25;Variation=100。

 在3D Max中创建星球爆炸[教程] - 石像鬼 - 鬼喊鬼叫

Set the Speed operator settings to Speed=35; Variation=30,Direction=Icon Center Out; Divergence=90., and the Spin settings to Spin rate=120;Variation=100.

设置Speed operator 为Speed=35; Variation=30,Direction=Icon Center Out; Divergence=90;Spin设置为Spin rate=120;Variation=100。

在3D Max中创建星球爆炸[教程] - 石像鬼 - 鬼喊鬼叫

Connect the Spawn operator to the Event 03. Adjust the Spawn 01 operator offspring setting to 10. Beware to adjust the setting depending on your PC power range.

连接Spawn operator到Event 03.调整Spawn 01 operator offspring设置为10,注意根据你电脑的承受能力来调整。

The animation is much better now. You can play with your own settings, add more deflectors etc. Feel free to post your planet destruction links below and see if you could blow up a planet, "How would you have it happen?"

I hope you have find this tutorial helpful.

现在看起来好多了,你可以根据自己需要多调整一下参数。

希望这个教程对你们有帮助。记得给我的Blog多带来些人气。
