# GPU Cloth Simulation | ||
|
||
This repository is about GPU based Mass-Spring Simuation in Unity. This project is a sub project of [ReclothSimulation-master](), some of features are removed. | ||
|
||
- Mass Spring System Cloth | ||
- ~~Inter Object Collision-Response~~ | ||
- ~~Self Collision-Response~~ | ||
- ~~Dynamic Collider Generation~~ | ||
|
||
Currently Confirmed working on following platforms: | ||
|
||
- Unity Engine version 5.6.1f2 ~ 2018.2.0b10 | ||
- Windows(OpenGL Core) | ||
- Android(OpenGL Core) | ||
|
||
## How to use | ||
|
||
Create a empty GameObject on hierarchy panel and append [ClothSimuation]("../Assets/GPUClothModule/script/ClothSimulation.cs") and [ClothRenderer]("../Assets/GPUClothModule/script/ClothRenderer.cs") scripts on it. Since this simulation calculates with its own system, you'll need special materials and dedicated shaders for rendering. There are two example materials(Face Normal Rendering, Diffuse Rendering). | ||
|
||
### Attributes | ||
|
||
#### Cloth Simulation | ||
|
||
##### Compute Shaders | ||
|
||
attributes|description | ||
:---|:--- | ||
NodeUpdateComputeShader| a compute shader which updates forces, positions, velocities, etc. | ||
TriCollisionResponseComputeShader| a compute shader which calculates collision with floor | ||
NormalComputeShader| a compute shader which calculates all face normals of the cloth model | ||
|
||
##### Attribute of Cloth | ||
|
||
attributes|description | ||
:---|:--- | ||
VertexColumn|numbers of nodes in a Column | ||
VertexRow|numbers of nodes in a Row | ||
ClothSize|Size of cloth object in Unity world scale | ||
ClothMass|Mass of cloth object | ||
Looper|amount of looping compute shaders per frame, larger number for precise, slower simulation | ||
|
||
##### Constant for Cloth | ||
|
||
attributes|description | ||
---|--- | ||
SpringK|spring force from [Hooke's Law](https://en.wikipedia.org/wiki/Hooke%27s_law) | ||
Damping|damping coefficient for cloth simulation | ||
External Force|external forces such as wind, water etc. since it is public member, you can pass from external scripts | ||
|
||
#### Cloth Renderer | ||
|
||
### recommended parameters | ||
|
||
Since the simulation is not pretty stable, certain values for the clothSimulation scripts are recommended: | ||
|
||
attributes|values | ||
---|--- | ||
vertexColumn|8 ~ 64 | ||
vertexRow|8 ~ 64 | ||
Looper|20 ~ 500 | ||
Damping|100~200 | ||
