Fieldwork Model Evaluation Step

MAP Client plug-in for evaluating a fieldwork model at a regular discretisation.

Requires

None

Inputs

• ju#fieldworkmodel [GIAS3 Fieldwork Geometric Field instance] - a fieldwork model to be evaluated.

Outputs

• pointcloud [nx3 NumPy Array] - An array of point coordinates evaluated at a regular discretisation on the fieldwork model.

Configuration

• identifier : Unique name for the step.
• discretisation [list of ints]: The number of regularly-spaced points to sample in each element coordinate direction in each element of the fieldwork model. Should be of the format [d_1, d_2, ..., d_n] where d_i is the number of points to be sampled in element coordinate direction i. For example, to sample 10 by 10 points in each element in a 2-D surface mesh: [10,10].
• node coordinates [True|False] - Whether to return the model node coordinates instead of discretised points.
• elements - In which elements to evaluate the fieldwork model. Can be either
  • 'all' to evaluate all elements
  • A series of comma-separated integers and ranges defining the elements to evaluate, e.g. 1,2,5-10.

Usage

This step is used to discretise a fieldwork mesh model into a pointcloud by sampling elements at regular intervals in each element's local coordinate system.

To discrete a fieldwork model for triangulation, use Fieldwork Model Triangulation Step.
