作者: Lasse Rode / Studio xoio

The Berlin based studio xoio has been established in 2006 by Peter Stulz and Lasse Rode.     ghostxx
柏林工作室由Peter Stulz 和Lasse Rode成立于2006年。   

It is specialized in high-quality emotive architecture and product visualization.    
它是一家專業(yè)從事高質(zhì)量的建筑產(chǎn)品產(chǎn)品可視化公司。    

The team at xoio consists of people who have an architecture and design background.    
這個(gè)團(tuán)隊(duì)的成員在xoio里有建筑學(xué)和設(shè)計(jì)學(xué)的背景。    

That provides a strong understanding of creative processes and the ability to give support in questions of design.    
這提供了一個(gè)強(qiáng)大的理解能力和創(chuàng)意流程的支持在設(shè)計(jì)的問(wèn)題上。 

Introduction/介紹

Let me first point out how much we really dig this piece of software in our studio.    
讓我先指出我們真的喜歡這個(gè)軟件在我們的工作室里。    

Unlike other tools we used to grow foliage GrowFX is not too biological in its approach, but that makes it more flexible to adjust your growing objects the way YOU want them to behave.    
不像其他的工具,我們用來(lái)種植闊葉樹(shù)GrowFX不是太 生物學(xué) 的方法,但是,它能更加靈活的調(diào)整你的成長(zhǎng)對(duì)象按你所希望的方式來(lái)表現(xiàn)。    
 

Furthermore, GrowFX can handle a LOT of geometry inside of 3ds Max, which is indispensible for the creation of realistic trees.    
此外,GrowFX可以處理在3ds Max里創(chuàng)造真實(shí)的樹(shù)木所需的大量的幾何里面。    

An important thing to note is it is actively developed these days so you can expect more to come from the friendly developers which is important for any architectural visualization studio.    
要注意的重要一點(diǎn)是它最近積極發(fā)展了它的功能，你可以期望更多的來(lái)自友好的開(kāi)發(fā)人員是重要的,對(duì)于任何建筑可視化工作室來(lái)說(shuō)。

Before we get started in 3ds Max it is indispensible to do some research first, to have image references of trees you can always come back to.    
在我們開(kāi)始之前3ds Max軟件是不可或缺的,先做些研究,有樹(shù)木的圖像參考,讓您總是可以回到正確的軌道上。    

Otherwise, your trees will turn out generic and probably not very realistic.    
否則,你的樹(shù)將可能不是很真實(shí)。    

In this tutorial we want to cover the building of a tree for a specific project.    
在本教程中我們想設(shè)計(jì)一棵樹(shù)樹(shù)為一個(gè)具體的項(xiàng)目。    

We had several site photos featuring the trees needed to be part of the new building scheme.    
我們有幾個(gè)網(wǎng)站的照片展示了樹(shù)木需要成為新的建筑設(shè)計(jì)的一部分。    
 

A good tip is to look for some winter images of the same trees to get a better impression of the branching without all the leaves blocking the view.    
一個(gè)好的技巧是尋找一些冬天的圖像相同的樹(shù)種來(lái)獲得一個(gè)更好的分支結(jié)構(gòu)，因?yàn)闆](méi)有樹(shù)葉擋住視線。    
 

First  let me quickly explain the basic setup of any GrowFX Object. Any growth  object is consisted of one or more Elements. Each element has three  basic categories:

首先讓我快速解釋任何GrowFX對(duì)象的基本設(shè)置。任何生長(zhǎng)對(duì)象是由一個(gè)或多個(gè)元素組成。每個(gè)元素都有三個(gè)基本類別:
 

1. 根部 (分配器面板)

2. 路徑(修改窗口)

3. 網(wǎng)格(網(wǎng)格參數(shù)窗口)
    

1. The Root defines where the element starts and in which general direction it takes off.

   1.根定義元素開(kāi)始生長(zhǎng)的地方和生長(zhǎng)的方向。
    

2. The Path defines well the path on which the element is growing, how long it will be and how it evolve over the distance.

   2.定義好路徑 路徑?jīng)Q定元素如何生長(zhǎng),長(zhǎng)度以及它如何成長(zhǎng)的距離。
    

3. The  Mesh defines the visible representation the real render-able geometry.  Usually this will be a branch but it can also be other things like  leaves, fruits, or any other thing you can think about (don't limit  yourself to just the usual organic lifelike foliage).

   3.網(wǎng)格定義可見(jiàn)的模型 真正的渲染出來(lái)的幾何體。通常這將是指一些枝干,但它也可以是其他的東西,如樹(shù)葉、水果、或其他任何東西你可以想到的(不是你通常認(rèn)為的的有機(jī)的闊葉樹(shù))。
   
   

That is the order in which you should work your way up as you build your GrowFX object.

這是你的建立你的GrowFX對(duì)象的正常流程。
 

Each  one of these categories, I mentioned above, has a separate window you  can open, which makes it quite easy to treat them separately.

這些每一個(gè)類別中,我前面所提到的,您可以打開(kāi)一個(gè)單獨(dú)的窗口,這使得很容易把他們分開(kāi)。
 

1. Generate your GrowFX object/創(chuàng)建你的GrowFX物體。

Let's start with the trunk.    
讓我們先從樹(shù)干開(kāi)始。    

Before you generate anything it is a good advice to check your units.    
在您生成任何物體之前建議你先檢查你的單位設(shè)置。    

Otherwise you will spend hours tweaking your plants with the wrong scale and re-scaling is always prone to errors.    
否則你會(huì)花上幾個(gè)小時(shí)調(diào)整你的植物與錯(cuò)誤因?yàn)殄e(cuò)誤的單位導(dǎo)致這些問(wèn)題。   

We generate the GrowFX object, preferably in a separate scene.    
我們生成GrowFX對(duì)象,最好是在一個(gè)單獨(dú)的場(chǎng)景。    

The calculation load can get quite extreme as you progress so I woldn't recommend editing the GrowFX object inside the main scene file.    
計(jì)算負(fù)載可能會(huì)變得非常極端隨著你的進(jìn)展,所以我不推薦編輯GrowFX對(duì)象在你的主要場(chǎng)景文件。    

It is also best to start it at the scene origin 0,0,0.    
最好的開(kāi)始它在場(chǎng)景坐標(biāo)0,0,0上。

2. Generate the first element The Path/創(chuàng)建第一個(gè)元素-路徑

Next thing we create is our first path (1).    
下一件事我們創(chuàng)造是我們的第一個(gè)路徑(1)。    

It is a good idea to rename our first element to Trunk (2).    
這是一個(gè)好主意,我們的第一個(gè)元素重命名為 樹(shù)干(2)。    

It is important to get organized quickly, since we will jump back and forth a lot. Then we open the Root window (called distributor path) (3).    
組織迅速很重要,因?yàn)槲覀儗?lái)回跳轉(zhuǎn)很多次。然后我們打開(kāi)根窗口(稱為路徑分配器)（distributors）(3)。    

There are no distributors yet defined, so we create one (4).    
還沒(méi)有定義分配器（distributors）,所以我們創(chuàng)建一個(gè)(4)。    

Here is one great thing about GrowFX You have no limitations on how many distributors you define, which gives you great flexibility on how you can place things (5).    
這是GrowFX一個(gè)偉大的功能 你沒(méi)有被限制你定義多少個(gè)分配器（distributors）,它能給你帶來(lái)巨大的靈活性來(lái)放置你的物體(5)。    

Finally, we take a simple Distributor which lets our trunk start straight in the icon center.    
最后,我們以一個(gè)簡(jiǎn)單的分配器（distributors）可以讓我們的樹(shù)干開(kāi)始筆直得沿著圖標(biāo)中心生長(zhǎng)。    
 

3. Generate modifiers/創(chuàng)建修改器

To influence our paths we open the modify window (1).    
為了影響我們的路徑我們打開(kāi)修改窗口(1)。    

In the next step you would adjust the total length of the path (2).    
在下一步你會(huì)調(diào)整路徑的總長(zhǎng)度(2)。    

In this case the length of the trunk.    
在這種情況下樹(shù)干的長(zhǎng)度。    

Now we should see an unmodified straight path in the viewport.    
現(xiàn)在我們應(yīng)該會(huì)看到一個(gè)未修改的直線路徑在視窗中。    

To influence our path we create our first modifier (3).    
影響我們的路徑,我們創(chuàng)建我們的第一個(gè)修改器(3)。    

Choose a modifier you would like to use (4).    
選擇一個(gè)您希望使用修改器(4)。    

Here we get to a point where you can make great use of the help documentation that ships with GrowFX.    
這里我們打開(kāi)讓你可以造就好效果的GrowFX使用幫助文檔。    

The graphical symbols are pretty explanatory and the descriptions give you a good idea what each of the modifiers are doing.    
圖形符號(hào)是很漂亮的，它們解釋和描述給你每個(gè)修飾符是做什么的。    
 

The choice of modifiers seems overwhelming at first glance, but in fact it is well-chosen and gives you great control.    
修改器的選擇似乎很亂在乍看之下,但實(shí)際上它都是經(jīng)過(guò)精心挑選的,能給你帶來(lái)巨大的控制力。    

There is actually no way around testing each one of them by yourself and seeing what they do.    
事實(shí)上沒(méi)有辦法測(cè)試每一個(gè)修改器,你們自己可以測(cè)試看它們是做什么的。    

One great thing about GrowFX is that you can stack modifiers easily and a turn them on and off (by hitting the light bulb), so you can test them separately.    
GrowFX的妙處之一就是你可以輕松堆疊修改器打開(kāi)和關(guān)閉它們(通過(guò)點(diǎn)擊燈泡),所以你可以單獨(dú)測(cè)試它們。    
 

You really need to test the settings yourself and get familiar with each one of them to fine-tune the object growth.    
你真的需要測(cè)試設(shè)置來(lái)熟悉每一個(gè)能夠調(diào)整增長(zhǎng)的對(duì)象。    

The three most important modifiers are random, noise and vector.    
三個(gè)最重要的修改器是隨機(jī),噪波和向量。    
 

1. Random Changes the path direction according to a fractal pattern

   1.隨機(jī)改變路徑方向根據(jù)分形圖案 .  
    

2. Noise keeps the general direction but varies the path underneath

   2.噪波修改器保持總的方向但是讓路徑產(chǎn)生隨機(jī)性.   
    

3. Vector bends your path according to a given direction. This is used mostly for gravitational influences.

   3.矢量修改器彎曲你的路徑向量根據(jù)給定的方向。這主要用于引力影響。
    

For the trunk I used a simple setup consisting of one random modifier and one Noise modifier.    
對(duì)于樹(shù)干我使用一個(gè)簡(jiǎn)單的設(shè)置由一個(gè)隨機(jī)修改器和一個(gè)噪波修改器。    

You probably need to adjust some scale and strength values to get some reasonable results.    
你可能需要調(diào)整一些縮放和強(qiáng)度值來(lái)得到一些合理的結(jié)果。    
 

One  downside about the user interface at this point is, that you can change  values of modifiers that are switched off. You will find yourself  fiddling around with some values, seeing no changes and probably messing  up a modifier that is switched off. Keep that in mind.

關(guān)于用戶界面的一個(gè)缺點(diǎn)是,您可以更改已經(jīng)關(guān)掉的修改器的參數(shù)。你會(huì)發(fā)現(xiàn)自己擺弄著一些值,看到?jīng)]有變化,這可能攪亂一個(gè)修改器的參數(shù)。記住這一點(diǎn)。

4. Creating first meshes/創(chuàng)建第一個(gè)mesh

Now we get to create a render-able representation for our path (1).    
現(xiàn)在讓我們來(lái)創(chuàng)建一個(gè)可以表示為我們的路徑的可渲染網(wǎng)格(1)。    

Open the mesh editor (2).    
打開(kāi)網(wǎng)格編輯器(2)。    

Turn line display off so you can see what you are doing (3).    
把線顯示關(guān)了,這樣你就可以看到你正在做的事情(3)。    

Create a mesh (4).    
創(chuàng)建一個(gè)網(wǎng)格(4)。    

Choose the mesh type.    
選擇網(wǎng)格類型。    

For all kinds of branch structures it is advisable to start with a simple cylindrical mesh.    
對(duì)于所有種類的分支結(jié)構(gòu)建議開(kāi)始用一個(gè)簡(jiǎn)單的圓柱形網(wǎng)格類型。    

The meta mesh, does basically the same, but welds branch structures when they intersect.    
meta網(wǎng)格,基本上是相同的,但是當(dāng)他們交叉縫分支結(jié)構(gòu)是圓滑焊接的。    

That is quite revolutionary in our opinion, but also takes a lot of time to build, so we normally save this step for last.    
那是相當(dāng)?shù)母锩谖覀兛磥?lái),但是還需要花大量的時(shí)間去構(gòu)建,所以我們通常保存這個(gè)步驟最后。    

The other meshes are,m well other meshes, all things other than branches.    
其他的網(wǎng)格都不同于分支結(jié)構(gòu)。    
 

5. Adjusting Meshes/調(diào)節(jié)網(wǎng)格

Now you should see a simple cylindrical shell, which is probably highly tessellated.    
現(xiàn)在您應(yīng)該看到一個(gè)簡(jiǎn)單的圓柱體,這可能是高度程序化的。    

To adjust the density to a reasonable level you can adjust the shape sub steps in the direction window (1).    
調(diào)整密度到合理水平,你可以調(diào)整形狀在方向面板(1)。    

And the circular density in the minimum faces spinner in the mesh window (2).    
最低密度在網(wǎng)格面板(2)。    

To influence the radius in a more natural way we open a curve window by clicking the little curve icon besides the radius spinner (3).    
影響半徑更為自然的方式，我們打開(kāi)一個(gè)曲線窗口點(diǎn)擊小曲線圖標(biāo)(3)。    

GrowFX uses a lot the internal curve editors, always adjusting Value over Distance.    
GrowFX使用大量?jī)?nèi)部曲線編輯,可以超越直接調(diào)節(jié)數(shù)值。    

In this case Radius over Growth Length of the Trunk (4).    
在這種情況下半徑優(yōu)先于樹(shù)干的生長(zhǎng)的長(zhǎng)度(4)。

6. Adjusting UVW Maps/調(diào)節(jié)UVW貼圖

GrowFX has a very functional but efficient way of texture mapping.   
GrowFX有一個(gè)非常有效的功能關(guān)于紋理映射。   

Scroll down on the mesh editor and hit the broad UVW Mapping button (1).   
向下滾動(dòng)網(wǎng)格編輯器和擊點(diǎn)擊UVW映射按鈕(1)。   

This should open up a new submenu.   
這應(yīng)該會(huì)打開(kāi)一個(gè)新的子菜單。   

I created a quick checker map material, assigned it and tested some absolute values (2).   
我創(chuàng)建了一個(gè)快速檢查程序貼圖材質(zhì),指定它,測(cè)試了一些絕對(duì)的參數(shù)(2)。   

Later you should replace the map with some bark of your choice.   
以后你應(yīng)該取代貼圖用您選擇的一些樹(shù)皮貼圖。   

It is generally a good idea to have a slightly larger structure on the main trunk gradually getting smaller moving up.

通常是一個(gè)好主意：要稍微更大的結(jié)構(gòu)在主干向上逐漸變小。   
 

For later use with a multi map you can quickly assign the material ID above (3).

供以后使用多種貼圖你可以迅速分配材質(zhì)ID(3)。   
 

7. Adding elements/增加元素物體

Based on our trunk we now start adding additional elements.    
基于我們的樹(shù)干我們現(xiàn)在開(kāi)始添加額外的元素。    

We create a new path (1).    
我們創(chuàng)建一個(gè)新的路徑(1)。    

Rename it to Branches (2).    
將其重命名為 分支(2)。    

We create a new distributor (3).    
我們創(chuàng)建一個(gè)新的分配器(3)。    

And choose a path distributor.    
選擇路徑分配器。    

This modifier lets us root our branches on other paths.    
這個(gè)修改器讓我們我們?cè)谄渌窂缴喜迦霕?shù)枝。    

We add a root path and choose our trunk (4).    
我們添加一個(gè)根路徑并選擇我們的樹(shù)干(4)。    

If you switch to line display (5),    
如果您切換到顯示線上(5),    

you should now see the newly generated paths.    
您現(xiàn)在應(yīng)該看到新生成的路徑。    
 

8. Using Affectors/使用影響器

An important feature in GrowFX are Affectors.    
GrowFX的一個(gè)重要的功能是產(chǎn)生的影響因素。    

These basically represent one value affecting another value in the same hierarchy or deeper.    
這代表一個(gè)值能影響另一個(gè)值在同一層次結(jié)構(gòu)或更深層次。    

In this case we want, the relational position of the branches to influence the length of itself.    
在本例中,我們想要展示分支的相關(guān)的位置影響自己的長(zhǎng)度。    

In other words, the further up the branches are, the shorter they get.    
換句話說(shuō),進(jìn)一步的分支,使得它們更短。    
 

Make sure your branch element is selected.    
確保你的分支元素被選中。    

Open the Affector control (1),    
打開(kāi)Affector控制(1),    

based on the branch position.Add a new Affector (2), 
基于分支位置，添加一個(gè)新的Affector(2),   

and pick the branch length you want to control.    
選擇分支長(zhǎng)度你想控制的。    

Add a curve representation (3),    
添加一個(gè)曲線控制器(3),    

and edit the curve to your liking (4).    
編輯曲線按照你的喜好(4)。    

See the first results in the viewport representation.    
看到第一個(gè)結(jié)果在視窗中顯示。  

9. Move on by yourself/自己繼續(xù)前進(jìn)

From here on you know all the parameters needed to generate tree structures.    
到這里你知道所有的參數(shù)關(guān)于需要生成樹(shù)結(jié)構(gòu)。    

Honestly, it would take 50 extra pages to get all the fine-tuning detailed here, so I will not go any deeper into the process.    
老實(shí)說(shuō),這將花費(fèi)50額外頁(yè)數(shù)獲得所有的微調(diào)詳細(xì)參數(shù),所以我不會(huì)去演示任何更深的過(guò)程。    

Furthermore you really must try this solo to understand it fully and in a way you can repeat it and elaborate on it.    
而且你真的必須試著去理解它,在某種程度上你可以重復(fù)和詳細(xì)測(cè)試它。    

Be sure to double-check your references a lot, to make sure you stay on track.    
一定要仔細(xì)檢查你的參考圖片,以確保你保持正確的前進(jìn)方向。    

Sometimes it is better to switch back to your root elements and turn all other elements off again.    
有時(shí)最好切換回你的根元素,并關(guān)閉所有其他元素。    

The nice thing about GrowFX is, you can easily test settings and compare them by turning things on and off.    
GrowFX的好處是,您可以輕松地測(cè)試設(shè)置并比較他們，只要開(kāi)關(guān)一些按鈕就行了。    
 

Here you see the full branching, consisting of 4 elements.    
這里你看到完整的分支,由4個(gè)元素組成。    

To the very right you can see, that we tested various configurations and kept some turned off.    
你可以看到,我們測(cè)試了各種配置并關(guān)掉了一些修改器。    

You have lots of control how your branching works.    
你有很多分支是由你控制的。    

We kept the start value in general relatively high, to get a tree that is light in the inside and has fluffy balls of leaves towards the edges.    
我們保留了啟動(dòng)值一般來(lái)說(shuō)相對(duì)較高,得到一個(gè)樹(shù),樹(shù)冠內(nèi)部比較空，越往外樹(shù)葉越密。  

10. Custom Leaves/自定義樹(shù)葉

GrowFX offers various leave meshes which are ok.    
GrowFX提供了各種樹(shù)葉的網(wǎng)格。    

But since we want loads of leaves they will definitely make the biggest part of the mesh load generated.    
但是由于我們要加載的葉子，他們肯定會(huì)是網(wǎng)格負(fù)載的主體。    

So we rather generate our own optimized mesh, which uses the least amount of polygons to get the result we are after.    
所以我們自己制作我們的優(yōu)化網(wǎng)格,它使用最少的多邊形來(lái)獲取我們想要的最好的結(jié)果。    
 

Since xoio studio mostly relies on V-Ray, and occasionally on Mental Ray, alpha maps are an issue.    
因?yàn)閤oio工作室主要依賴于vray渲染,偶爾使用Mental Ray,alpha貼圖是一個(gè)問(wèn)題（意思是ALPHA貼圖在這兩種渲染器里發(fā)揮的不好，效率不高）。    

We always try to keep render times as low as possible and alpha maps can be a killer in both engines.    
我們總是試圖保持渲染時(shí)間盡可能低，阿爾法貼圖在兩個(gè)引擎中是一個(gè)殺手。    

Therefore we build the depicted custom leave which includes the stem and forms a nice round leave-shape with 7 triangles / 3.5 quads.    
因此我們構(gòu)建葉片模型包括葉子的桿子和一個(gè)有7個(gè)三角面的不錯(cuò)的圓形物體。    

It is slightly bent to give nice reflections.    
稍微一些彎曲獲得漂亮的反射。    
 

One important modifier for the use with leaves is the vector orient modifier which guarantees that your leaves all face upwards.    
一個(gè)重要的修改器是在樹(shù)葉上使用vector orient修改器,可以保證你的葉子都面臨向上。    

May be you need to turn your base instance mesh on a sub-object level, if they all look sideways instead.    
可能你需要翻轉(zhuǎn)你的基礎(chǔ)實(shí)例網(wǎng)格在對(duì)象級(jí)別,如果它們都看起來(lái)翻轉(zhuǎn)了。    
 

11. General Workflow Tips/工作流程小貼士

Meta Meshes/meta網(wǎng)格

In the upper image you can see the metamesh (trunk) versus the standard cylinder (bough).    
在上面的圖片中你可以看到metamesh(主干)與標(biāo)準(zhǔn)的圓柱體的區(qū)別(枝干)。    

While the metamesh nicely connects the elements, the cylindrical elements stick into each other.    
metamesh連接元素很平滑,圓柱元素是直接插入對(duì)方的。    

Since metamesh construction can take a lot of time, we keep always two mesh constructors in the stack, one cylindrical and one meta constructor.    
因?yàn)閙etamesh創(chuàng)建,需要花費(fèi)大量的時(shí)間,所以我們保持兩個(gè)網(wǎng)格構(gòu)造函數(shù)的堆棧,一個(gè)圓柱和一個(gè)meta 函數(shù)。    

This way, you can easily switch between both for speed purposes.    
這種方式,你可以很容易的切換兩種構(gòu)建方式。    

For the smaller branches metameshes are generally not necessary or even visible.    
對(duì)于小的樹(shù)枝metameshes通常沒(méi)有必要甚至是不必要可見(jiàn)的。

Test Branches/測(cè)試效果

It can become quite tiresome if you need to judge the branching in a later stage and rebuilding starts to take ages.    
如果你需要判斷分支在后面的階段并重建會(huì)變得非常煩人和花費(fèi)時(shí)間。    

So to speed up the workflow, we inserted a new distributor, which generates only one branch.    
因此加快工作流,我們插入一個(gè)新的分配器,它只有一個(gè)分支。    

Turning the other branches off, rebuilding gets way faster.    
將其他分支都關(guān)掉,重建得到更快的方式。    

So you can judge all your branching settings quickly and always switch back to get the full tree.    
所以你可以判斷你所有的分支設(shè)置通過(guò)迅速切換回得到完整的樹(shù)。    

Mesh Load/載入網(wǎng)格物體

Do not be afraid of a LOT of geometry.    
不要害怕大量的幾何面數(shù)。    

Of course things tend to get really slow in the end, but if you really want some realistic tree, you will end up with several hundred thousand triangles.    
當(dāng)然,事情往往會(huì)變得很慢到最后,但如果你真的想要一些真實(shí)的樹(shù),你最終會(huì)達(dá)到數(shù)十萬(wàn)上百萬(wàn)三角面。    

The tree above has 1.3 Million polygons.    
圖中的樹(shù)有130萬(wàn)個(gè)多邊形。    

You can always get less geometry by using alpha maps for the trees.    
你總是可以得到更少的幾何面數(shù)通過(guò)使用alpha貼圖的樹(shù)木。    

But from our experience with alpha maps, that incur long render times, it is better to use higher poly-count and it will render faster.
