Clipping geometries

To use a clipping geometry in combination with a Remeshing- or Aggregation pipeline two selection sets needs to be created. The first set is the "ProcessSelectionSet" which includes all meshes in the scene that should be processed, the second set is the "ClippingSelectionSet" which includes meshes that should be used as clipping geometries.

For Aggregation: Triangles that are on the negative normal side of the clipping geometry will be removed.

For Remeshing: Triangles that are on the negative normal side of the clipping geometry will be removed. Triangles that intersects with the clipping geometry will be clipped and removed if on the negative normal side of the clipping geometry.

Selection sets:

-- load a remeshing pipeline
remeshingPipeline = sgsdk_LoadPipeline "D:/Pipelines/remeshingPipelineWithBaking.json"

-- set the process selection set
bResult = sgsdk_SetSetting remeshingPipeline "RemeshingProcessor/RemeshingSettings/ProcessSelectionSetName" "ProcessSelectionSet"

-- set the clipping selection set
bResult = sgsdk_SetSetting remeshingPipeline "RemeshingProcessor/RemeshingSettings/ClippingGeometrySelectionSetName" "ClippingSelectionSet"

-- pass the settings object to the Simplygon function
bResult = sgsdk_RunPipelineOnSelection remeshingPipeline

-- clear all pipelines
sgsdk_ClearPipelines()

from pymxs import runtime as rt

# load a remeshing pipeline
remeshingPipeline = rt.sgsdk_LoadPipeline('D:/Pipelines/remeshingPipelineWithBaking.json')

# set the process selection set
bResult = rt.sgsdk_SetSetting(remeshingPipeline, 'RemeshingProcessor/RemeshingSettings/ProcessSelectionSetName', 'ProcessSelectionSet')

# set the clipping selection set
bResult = rt.sgsdk_SetSetting(remeshingPipeline, 'RemeshingProcessor/RemeshingSettings/ClippingGeometrySelectionSetName', 'ClippingSelectionSet')

# pass the settings object to the Simplygon function
bResult = rt.sgsdk_RunPipelineOnSelection(remeshingPipeline)

# clear all pipelines
rt.sgsdk_ClearPipelines()
