mesh:decimate mesh

Version: 0.0.0

Description

Decimate a meshed region

Inputs

This table lists the input pins for this operator. Input pins define the data that the operator requires to perform its operation. Some inputs are required, while others are optional and provide additional configuration. Each parameter is detailed in the sections that follow the table.

mesh (Pin 0)

• Required: Yes
• Expected type(s): abstract_meshed_region

Mesh to decimate

preservation_ratio (Pin 1)

• Required: No
• Expected type(s): double

Target ratio of elements to preserve, the actual number of elements preserved might differ. Default value is 0.5.

aggressiveness (Pin 2)

• Required: No
• Expected type(s): int32

Quality measure for the resulting decimated mesh. Lower aggresiveness will provide a higher quality mesh with the tradeoff of higher execution time. Value range is 0 to 150, default is 0.

Outputs

This table lists the output pins for this operator. Output pins provide the results of the operator's computation and can be connected to inputs of other operators or retrieved for further processing. Each output is detailed in the sections that follow the table.

mesh (Pin 0)

• Expected type(s): abstract_meshed_region

Decimated mesh with triangle elements

Configurations

This operator supports configuration options that modify its behavior.

mutex

• Expected type(s): bool
• Default value: false

If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads.

Scripting

This operator can be accessed through scripting interfaces using these identifiers.

Examples

These examples demonstrate how to use this operator in different programming environments. Each example shows how to instantiate the operator, connect the required inputs, and retrieve the output.

#include "dpf_api.h"

ansys::dpf::Operator op("decimate_mesh"); // operator instantiation
op.connect(0, my_mesh);
op.connect(1, my_preservation_ratio);
op.connect(2, my_aggressiveness);
ansys::dpf::MeshedRegion my_mesh = op.getOutput<ansys::dpf::MeshedRegion>(0);

import ansys.dpf.core as dpf

op = dpf.operators.mesh.None() # operator instantiation
op.inputs.mesh.connect(my_mesh)
op.inputs.preservation_ratio.connect(my_preservation_ratio)
op.inputs.aggressiveness.connect(my_aggressiveness)
my_mesh = op.outputs.mesh()

import mech_dpf
import Ans.DataProcessing as dpf

op = dpf.operators.mesh.None() # operator instantiation
op.inputs.mesh.Connect(my_mesh)
op.inputs.preservation_ratio.Connect(my_preservation_ratio)
op.inputs.aggressiveness.Connect(my_aggressiveness)
my_mesh = op.outputs.mesh.GetData()
