## README

将ECEF坐标的廓线数据Geojson，转为管子（pipe）的多边形数据，保存为json格式。

--------------

## 2026/6/16
v1.1 每个vertex增加颜色属性，颜色来源为廓线的属性值与预定义的ColorBar。
调用方式：

无颜色模式：
yy_prf_pipe.exe radius segcnt /dir/in/ecef.geojson /out/put/pipe.json 


有颜色模式：
yy_prf_pipe.exe radius segcnt pptyIndex color.json /dir/in/ecef.geojson /out/put/pipe.json


### 输入
json数据文件中，每个Feature的coordinates 字段中每个点前三个值表示xyz坐标，后面都是属性值。 样例如下
属性编号从0开始（x），依次类推，那么第一个属性对应 属性索引值为3。

### 配色文件
使用json格式，采用OEE的样式：

~~~
{"type":"linear",
"bands":[0],
"nodatacolor":{"val":0,"r":0,"g":0,"b":0,"a":0,"lbl":"NoData"},
"vranges":[{"minval":0,"maxval":1000}],
"belowMinTransparent":true,
"aboveMaxTransparent":true,
"colors":[
 {"val":0,"r":255,"g":255,"b":255,"a":0,"lbl":"   0"}
,{"val":100,"r":1,"g":160,"b":246,"a":255,"lbl":"  10"}
,{"val":150,"r":0,"g":236,"b":236,"a":255,"lbl":"  15"}
,{"val":200,"r":0,"g":216,"b":0,"a":255,"lbl":"  20"}
,{"val":250,"r":1,"g":144,"b":0,"a":255,"lbl":"  25"}

### 输出结果
json格式如下，顶点颜色采用三个Byte整形数字表示。


~~~
{
"nver":1000,
"nind":3000,
"ntri":1000,
"verts":[ [492.0 , 250.0 , 329.5 ] , ... ...],
"indis":[ 0,1,2, 0,2,3, ... ... ],
"colrs":[ [255,0,0] , ... ... ]  //数量与verts一致
}
