Maya Tutorial- Deformers (Part 01)

文/圖 莊澤光

 

本篇教程在說明如何使用Maya 一系列的Deformer。尤於數量眾多，會將本篇分為兩章來討論。而之後也會慢慢的再繼律更新其內容。原本Maya Deformer應屬於較基礎的應用，但一來Maya Deformer在Maya 2016中有些功能有大幅改變，二來其在建模、設置參數化互動模型上有著直接的幫助，若搭配Rigging的話便能產生十分直觀的參數化互動模型，非常實用:故放在Maya Adv. Tutorial之中。

 

Deformer01- BlendShape

 

此功能原用在動畫的臉部表情變型之上-舉例來講便是建模者建造一基本頭部模型，複製一個後將此模型調整到他想要的表情，之後再用BlendShape便能產生中間連續性的變化。而對設計人而言則可作為過程模型的生成。必須注意的是此功能僅能對應面數相同的多邊型；若不同會產生意料之外的結果。

Maya Tutorial- Real-time tension mapping

Small trick for Maya Lovers (who’s suffering with rhino & grasshopper)

Real-time compression/tension(stretch) and curvature mapping for early form finding and optimization.

This node from SOuP probably has been used for character modeling with rigged mesh, which are Skeleton or SkinCluster, you can find a lot of tutorial online. But, here we will use nonlinear deform and nCloth as examples easier applied to architecture design and fake some structural optimization.

1^st. Install SOuP for Maya

Download line is here http://www.soup-dev.com/tools.htm

Please follow official readme.txt to install, super easy steps. If you cannot find some folders in windows 8, mine is @ C:\Users\damon\Documents\maya\2015-x64\prefs

2^nd. Basic Principle

This node works with rest shape and modified shape, which means by comparing the original shape and the shape after deform, this node outputs color mapping result to the geometry. (Any kinds of changing, like nCloth physics, nonlinear deform, rigged, or blendshapes… so on n so 4)

Here we setup a bending mesh using nonlinear deform as first simple example.

Here, in the shading group, you only have to focus on only those highlighted, no need to care other complex connections (which are preset already by software itself)

Maya Tutorial- Maya Particle 粒子模擬

本篇教程在說明如何使用Maya N Particle，以及將這些不可抓摸的粒子轉為幾何體，以進階利用於建築幾何體之上。本文以Maya2016為基礎，有些部份會與舊版不同，但原理一樣。與Fluid系統類似，但最大的差別是前者須限制一界限範圍，而後者則否。以動畫應用面來講，如果是大體積的流體模擬，使用Fluid會較合適；若是如水柱、噴泉、水花等小體積的流體，則用Particle較合適。此次的教學放在如合利用Particle去取代幾何型體，並利用另一Particle去產生碰撞、融蝕。
