tesselate_building
Console tool for creating a LOD1.2 triangulated polyhedralsurface from (building) footprint and height value. Colors per triangle are written to the 'colors' column. Buildings can have multiple storeys.
This tool is designed to create the correct input information for creating 3D tiles with pg2b3dm (https://github.com/Geodan/pg2b3dm)

Building Styling
For building styling a json column is used. Please note the the json keys are case sensitive.
Simple content (without storeys):
{
"walls": "#00ff00",
"roof": " #ff0000",
"floor": "#D3D3D3",
}
Style content with storeys:
{
"walls": "#00ff00",
"roof": " #ff0000",
"floor": "#D3D3D3",
"storeys": [
{
"from": 0,
"to": 0.5,
"color": "#D3D3D3"
},
{
"from": 0.5,
"to": 1,
"color": "#D3SS3D3"
},
{
"from": 1,
"to": 1.5,
"color": "#D354S3D3"
}
]
}
