### Generative Design "Defination"
#### There is no single solution; instead, there are potentially thousands of great solutions. You choose the design that best fits your needs
Generative design is a form finding process that can mimic nature's evolutionary approach to design. It can start with design goals and then explore innumerable possible permutations of a solution to find the best option. By using cloud computing, generative design can cycle through thousands or even millions of design choices, test configurations and learn from each iteration what works and what doesn't. The process can enable designers to generate brand new options, beyond what a human alone could create, to arrive at a most effective design.

### Use Cases
#### 1. Form Finding in Art, Architecture and Product
- <b><u>infinite Design Options:</u> </b>
<br>
In the time you can create one idea, a computer can generate thousands, along with the data to prove which designs perform best.
- <b><u>create complexity:</u></b>
<br>
Generative design lets you create optimized complex shapes and internal lattices. Some of these forms are impossible to make with traditional manufacturing methods. Instead, they're built using new additive manufacturing methods.
- <b><u>optimization:</u> </b>
<br>
for materials, manufacturing methods, and cost. Set goals and parameters, and the software will create high-performing design options based on those constraints. The software resolves conflicting design constraints so you can focus on innovating.

#### 2. Procedural Geometry Effect in Animation, Gaming and AR/VR.
- create <b><u>[complexity](http://pcgbook.com/)</u></b> and <b><u>[special effects](https://github.com/keijiro/Skinner)</u></b> that aren't exist in nature
<br>
