# LcLLib-for-Houdini
自定义Houdini HDA库，封装了一些自己常用的HDA节点，方便以后使用。顺便记录一下Houdini的一些知识点和Demo,方便以后查阅。
## 1. Houdini 自定义库安装教程
这里以我的自定义库 `LcLLib-for-Houdini`为例。
1. 创建一个LcL.json文件，并将其放在Houdini的库文件夹中，例如:`C:\Users\Administrator\Documents\houdini19.0\packages`
2. 在LcL.json文件中添加以下内容：
```json
{
"env": [
{
"LibPath": "F:/HoudiniProjects/libs"
}
],
"package_path" : [
"$LibPath/packages",
"$LibPath/LcLLib-for-Houdini/packages"
]
}
```
- `LibPath`为自定义库的路径。
- `package_path`为自定义库的子文件夹路径，可以有多个。
3. 在自定义库的packages文件夹中创建 `LcLLib.json`文件
并添加以下内容：
```json
{
"load_package_once": true,
"path": [
{
"value" : "$LibPath/LcLLib-for-Houdini",
"method" : "prepend",
},
],
"env": [
{
"LcLLib": "$LibPath/LcLLib-for-Houdini"
},
{
"HOUDINI_SCRIPT_PATH": {
"method": "prepend",
"value": [
"$LcLLib/scripts",
]
}
},
{
"HOUDINI_OTLSCAN_PATH": {
"method": "append",
"value": [
"$LcLLib/otls/geo",
"$LcLLib/otls/grass",
"$LcLLib/otls/road",
"$LcLLib/otls/rock",
"$LcLLib/otls/terrain",
"$LcLLib/otls/tools",
"$LcLLib/otls/track",
"$LcLLib/otls/tree",
]
}
},
{
"HOUDINI_VEX_PATH": {
"method": "append",
"value": [
"$LcLLib/vex/^",
]
}
},
{
"HOUDINI_OCL_PATH": {
"method": "append",
"value": [
"$LcLLib/ocl",
]
}
},
],
}
```
- `load_package_once`为true时，只加载一次自定义库。
- `path`为自定义库的路径。
- `env`为自定义库的环境变量，可以有多个。
## 2. LcLLib-for-Houdini 的Example文件
### [雨滴水波模拟](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/examples/water)
### [简单的烟雾模拟](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/examples/smoke)
## 3. LcLLib-for-Houdini 的HDA节点
### [LcL Water Wave Tools](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/otls/tools)
`HDA: water_wave`
用于创建无缝FFT海水，可以通过修改参数来调整海水的大小、波长、波高、波速、波向、波的数量等。
支持导出序列帧法线贴图。
合成后的法线贴图（8x8）
### [LcL Noise Creator](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/otls/tools)
`HDA: noise_creator`
用于创建噪声贴图，支持多种噪声类型，例如Perlin、Worley、Voronoi、Cellular、Simplex、Value等。
### [LcL Gpa Data Importer](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/otls/tools)
GPA截帧数据导入器，用于把GPA导出的CSV数据写入FBX中，例如uv、法线、顶点颜色等。
原本GPA导出的obj是没有uv等数据的。
csv文件格式：
写入FBX后的效果：
### [lcl_scater_non_overlapping](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/otls/particle)
不重叠撒点，在 `scatter align` 节点基础上封装，剔除了重叠的Point
### [lcl_meteorite_scatter](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/otls/particle)
陨石分布
### [lcl_import_volume_texture](https://github.com/csdjk/LcLLib-for-Houdini/tree/main/otls/volume)
导入3D Texture序列，转成Volume
