Workflows properties - geosolutions-it/digital-twin-toolbox GitHub Wiki

This application provides different workflows based on the input data: vector or point cloud. Each workflow exposes configurable properties for the supported processes.

Below are listed available properties divided by type of workflow.

Vector polygons workflow properties

The vector polygon workflow initializes when a shapefile asset with point polygon is associated with a pipeline, the interactive form lists the following properties:

Name	Description
Lower limit height	lower limit in meters of generated extruded geometry. It can use expression
Upper limit height	upper limit in meters of generated extruded geometry. It can use expression
Translate z	translate all the geometry along the z axis for the given distance in meters. It can use expression
Maximum features per tile	number of maximum features per tile
Maximum geometric error	maximum geometric error, used to define when the tileset will be visible based on the distance from the camera
Geometric error factor	factor applied to the geometric error of the tileset (pg2b3dm --geometricerrorfactor)
Remove bottom surface	shading option for the generated mesh files inside the tileset
Add outline	add outlines to the generated mesh files inside the tileset (pg2b3dm --add_outlines)
Double sided	shading option for the generated mesh files inside the tileset
Max simplify tolerance (LOD) (experimental)	maximum simplify tolerance used when generating levels of detail. Only enabled when Add level of details is checked
Add level of details (experimental)	enable the generation of levels of detail (LOD) for the tileset

Vector point workflow properties

The vector point workflow initializes when a shapefile asset with point geometry is associated with a pipeline, the interactive form lists the following properties:

Name	Description
Model filename	the name of a .glb model available in the uploaded assets. It can use expression
Model rotation	the rotation of the model in degrees. It can use expression
Model scale	the scale of the model in meters. It can use expression
Translate z	translate all the geometry along the z axis for the given distance in meters. It can use expression
Maximum features per tile	number of maximum features per tile
Maximum geometric error	maximum geometric error, used to define when the tileset will be visible based on the distance from the camera

Point cloud workflow properties

The point cloud workflow initializes when a .las file s associated with a pipeline, the interactive form lists the following properties:

Name	Description
Sample radius	reduce the point cloud based on a radius in meters
Image for colorization	the name of a raster image available in the uploaded assets that could be used to colorize the point cloud
Convert to ellipsoidal height	try to convert the point height to ellipsoidal values
Ground classification	apply the ground classification
Geometric error scale factor	a factor to adjust the default geometric error generated by the process. This value is applied to all the geometricError in the tileset.json with by multiplication

[!NOTE] The point cloud form also exposes a Point size input under a Preview section. This only affects the local 3D preview rendering and is not part of the conversion pipeline.
