Detailed Description

Defines parameters used by the mesh generator.

Parameters can be set to and retrieved from the mesh generator using MeshGenerator::SetParameters() and MeshGenerator::Parameters() methods respectively.

Examples

meshing/mesh_generation/Program.cs, and meshing/mesh_generation/main.cxx.

Member Enumeration Documentation

GranularityType

enum class cadex::ModelAlgo::MeshGeneratorParameters::GranularityType

strong

Defines target accuracy of the mesh to be generated.

Defines pre-defined values for chordal and angular deflections:

	Fine	Medium	Coarse
chordal deflection	0.004 (0.4%)	0.01 (1%)	0.05 (5%)
angular deflection	20 degrees	45 degrees	60 degrees

The pre-defined values are applied when invoking MeshGeneratorParameters::SetGranularity().

Chordal and angular deflections can also be set to explicitly specified values using MeshGeneratorParameters::SetChordalDeflection() and MeshGeneratorParameters::SetAngularDeflection() methods.

Constructor & Destructor Documentation

MeshGeneratorParameters() [1/2]

cadex::ModelAlgo::MeshGeneratorParameters::MeshGeneratorParameters

(

)

Constructor.

Sets default parameter values according to GranularityType::Fine.

See also

SetGranularity().

MeshGeneratorParameters() [2/2]

cadex::ModelAlgo::MeshGeneratorParameters::MeshGeneratorParameters

(

GranularityType

theGranularity

)

Constructor.

Sets default parameter values according to theGranularity.

See also

SetGranularity().

Member Function Documentation

AngularDeflection()

double cadex::ModelAlgo::MeshGeneratorParameters::AngularDeflection

(

)

const

Returns angular deflection.

See also

SetAngularDeflection().

ChordalDeflection()

double cadex::ModelAlgo::MeshGeneratorParameters::ChordalDeflection

(

)

const

Returns chordal deflection.

Returns a relative or absolute value of the chordal deflection depending on the value returned by IsRelativeChordalDeflection().

Default value is 0.004 (0.4%) for IsRelativeChordalDeflection() true.

See also

SetChordalDeflection().

Granularity()

MeshGeneratorParameters::GranularityType cadex::ModelAlgo::MeshGeneratorParameters::Granularity

(

)

const

Returns a granularity value.

See also

SetGranularity().

IsRelativeChordalDeflection()

bool cadex::ModelAlgo::MeshGeneratorParameters::IsRelativeChordalDeflection

(

)

const

Returns whether ChordalDeflection() contains an absolute or relative value.

By default is true.

See also

SetIsRelativeChordalDeflection().

SetAngularDeflection()

void cadex::ModelAlgo::MeshGeneratorParameters::SetAngularDeflection

(

double

theValue

)

Sets angular deflection.

Specifies a maximum deviation (in radians) between tangents at two adjacent mesh nodes when tessellating an edge curve or between normals when tessellating a face surface.

Default value in radians is equal to 20 degrees.

Sets granularity to Custom.

Examples

meshing/mesh_generation/Program.cs, and meshing/mesh_generation/main.cxx.

SetChordalDeflection()

void cadex::ModelAlgo::MeshGeneratorParameters::SetChordalDeflection

(

double

theValue

)

Sets chordal deflection.

Specifies either a value relative to the body bounding box (if IsRelativeChordalDeflection() is true) or an absolute value of the maximum deflection of the visualization mesh.

Chordal deflection is basically a deviation of the triangles from the original surfaces or curves. Default value is 0.004 (0.4%) for IsRelativeChordalDeflection() true.

Note that in some cases the algorithm can produce more coarse triangulation.

Sets granularity to Custom.

See also

ChordalDeflection().

Examples

meshing/mesh_generation/Program.cs, and meshing/mesh_generation/main.cxx.

SetGranularity()

void cadex::ModelAlgo::MeshGeneratorParameters::SetGranularity

(

GranularityType

theGranularity

)

If theGranularity is Custom then does nothing.

Otherwise sets chordal and angular deflections according to the specified granularity value. Refer to the table in the description of the GranularityType. IsRelativeChordalDeflection() is set to true.

See also

GetGranularity().

SetIsRelativeChordalDeflection()

void cadex::ModelAlgo::MeshGeneratorParameters::SetIsRelativeChordalDeflection

(

bool

theValue

)

Sets if ChordalDeflection() contains an absolute or relative value.

Specifies whether ChordalDeflection() contains an absolute (if false) or a relative to the shape bounding box (if true, by default) value of the deflection.

Sets granularity to Custom.
