Point3D

The Point3D Connector Type allows for Python Scripts to accept inputs of three-dimensional coordinates and to write three-dimensional coordinates to output connectors. The following script uses the Point3D Connector Type to accept a coordinate that is used as the centroid for the cube that it creates.

from mapteksdk.project import Project
from mapteksdk.data import Surface
from mapteksdk.workflows import (WorkflowArgumentParser, WorkflowSelection,
                                 Point3DConnectorType, DoubleConnectorType,
                                 StringConnectorType)

parser = WorkflowArgumentParser()
parser.declare_input_connector("path", StringConnectorType, default="/scrapbook/my_object")
parser.declare_input_connector("centroid", Point3DConnectorType, default=[0,0,0])
parser.declare_input_connector("size", DoubleConnectorType, default=10)

parser.declare_output_connector("selection", WorkflowSelection)

parser.parse_arguments()

points = numpy.array([[-0.5, -0.5, -0.5], [-0.5, -0.5, 0.5], [-0.5, 0.5, -0.5],
                   [-0.5, 0.5, 0.5], [0.5, -0.5, -0.5], [0.5, -0.5, 0.5],
                   [0.5, 0.5, -0.5], [0.5, 0.5, 0.5],])

points *= parser["size"]
points += parser["centroid"]

project = Project()

facets = [[0, 2, 1], [1, 2, 3],
          [4, 5, 6], [5, 7, 6],
          [0, 1, 5], [5, 4, 0],
          [1, 3, 5], [5, 3, 7],
          [2, 7, 3], [7, 2, 6],
          [0, 6, 2], [4, 6, 0]]

with project.new(parser["path"], Surface) as surface:
  surface.points = points
  surface.facets = facets

parser.set_output("selection", surface)

To run the above script, drag and drop the script onto an empty workflow. The workflow should look like this:

When you run the workflow, you should create an object in Maptek PointStudio that looks like this:
