viktor.external.dynamo

DynamoFile

class viktor.external.dynamo.DynamoFile(file)

Dynamo file instantiated from an existing input .dyn file. This class allows for easy transformation of input nodes by means of the update() method.

Parameters:

file (File) – Dynamo input file (.dyn).

generate()

Generate the (updated) Dynamo input file.

Return type:

File

get_node_id(name)

Retrieve the unique node id by name.

Parameters:

name (str) – Name of the node.

Return type:

str

update(name, value)

Update the value of an input node with specified name.

Parameters:

• name (str) – Name of the input node.

• value (Any) – New input value.

Return type:

None

convert_geometry_to_glb

viktor.external.dynamo.convert_geometry_to_glb(file, filter=None)

Convert a Dynamo geometry file (.json) to a GLB file, which can directly be used in a GeometryResult.

Filter specific geometric objects by id, obtained by calling get_node_id():

input_file = DynamoFile(file)
sphere_id = input_file.get_node_id("Sphere")  # geometry node called "Sphere"
...
geometry_file = dynamo_analysis.get_output_file(filename='geometry.json', as_file=True)  # viktor.external.generic.GenericAnalysis
glb_file = convert_geometry_to_glb(geometry_file, filter=[sphere_id])

Parameters:

• file (File) – Dynamo geometry file (.json).

• filter (List[str]) – Filter geometric objects by id (default: include all).

Return type:

File

get_dynamo_result

viktor.external.dynamo.get_dynamo_result(file, id_)

Extract results from a Dynamo output file (.xml) by means of a node ‘id’, which can be obtained by calling get_node_id().

Example using BytesIO:

input_file = DynamoFile(file)
output_id = input_file.get_node_id("Area")  # output node called "Area"
...
output_file = dynamo_analysis.get_output_file(filename='output.xml')  # viktor.external.generic.GenericAnalysis
result = get_dynamo_result(output_file, id_=output_id)

Example using File:

input_file = DynamoFile(file)
output_id = input_file.get_node_id("Area")  # output node called "Area"
...
output_file = dynamo_analysis.get_output_file(filename='output.xml', as_file=True)  # viktor.external.generic.GenericAnalysis
with output_file.open_binary() as f:
    result = get_dynamo_result(f, id_=output_id)

Parameters:

• file (BinaryIO) – Dynamo output file (.xml).

• id – Unique identifier of the output result node.

Return type:

str
