Member Typedef Documentation

◆ OdGiCalculateNormalCallback

typedef OdGeVector3d(* OdGiShellToolkit::OdGiCalculateNormalCallback) (OdGiShellToolkit *pToolkit, OdUInt32 nVertexIndex)

A data type that represents a pointer to a callback function for vertex normal calculation within custom applications.

Parameters

pToolkit	[in] A pointer to the current <link OdGiShellToolkit, shell toolkit> instance.
nVertexIndex	[in] An index of the vertex that is being processed.

Returns: An <exref target="https://docs.opendesign.com/tkernel/OdGeVector3d.html">OdGeVector3d</exref> object that represents the vertex normal.

Remarks: The implementation of the callback function must provide a normalized non-zero result.

Definition at line 453 of file GiShellToolkit.h.

Member Function Documentation

◆ addShell()

virtual bool OdGiShellToolkit::addShell	(	OdUInt32	nPoints,
		const OdGePoint3d *	pPoints,
		OdUInt32	nFaces,
		const OdInt32 *	pFaces,
		OdUInt8	options = OdGiShellToolkit::kTriangulateHoles )

pure virtual

Adds a shell to the <link OdGiShellToolkit, shell toolkit> object.

Parameters

nPoints	[in] The number of vertices.
pPoints	[in] An array of vertices that is represented with a pointer to its first element.
nFaces	[in] The size of the face list.
pFaces	[in] A face list. Each face is described with the number of vertices and indices from the vertex array (its size is equal to the number of vertices + 1).
options	[in] A byte value that contains <link OdGiShellToolkit::ShellToolkitOption, shell toolkit options>.

Returns: The true value if shell data is successfully added to the toolkit model; otherwise, it returns false.

Remarks: If the <link OdGiShellToolkit::ShellToolkitOption::kUnifyVertices, kUnifyVertices> option is enabled, only vertices from the specified shell are unified; vertices from previously added shell data are not modified. The <link OdGiShellToolkit::ShellToolkitOption::kForceTriangulation, kForceTriangulation> option includes the <link OdGiShellToolkit::ShellToolkitOption::kTriangulateHoles, kTriangulateHoles> option, so if it is enabled, the <link OdGiShellToolkit::ShellToolkitOption::kTriangulateHoles, kTriangulateHoles> option is not required. If the <link OdGiShellToolkit::ShellToolkitOption::kTriangulateHoles, kTriangulateHoles> and <link OdGiShellToolkit::ShellToolkitOption::kForceTriangulation, kForceTriangulation> options are disabled, holes are not supported. The <link OdGiShellToolkit::ShellToolkitOption::kKeepInitialData, kKeepInitialData> option guarantees that the number of faces and vertices are not modified. This option disables other options and limits toolkit functionality. Also, this option is specified only when processing a single shell.

◆ calculateAverageVertexNormals() [1/2]

virtual bool OdGiShellToolkit::calculateAverageVertexNormals ( OdArray< OdGeVector3d > & normals ) const

pure virtual

Calculates vertex average normals for the shell.

Parameters

normals [out] An array that stores the calculation results (normals are represented with <exref target="https://docs.opendesign.com/tkernel/OdGeVector3d.html">OdGeVector3d</exref> objects).

Returns: A Boolean value that is equal to true if all calculated normals are non-zero; otherwise, the method returns false.

Remarks: A normal index matches the vertex index in the vertex list. A normal being calculated as normalized is the sum of all face normals that contain vertices. A normal can be zero if a vertex is isolated or faces are not oriented in the same direction.

◆ calculateAverageVertexNormals() [2/2]

virtual bool OdGiShellToolkit::calculateAverageVertexNormals	(	OdArray< OdGeVector3d > &	normals,
		double	creaseAngelLimit,
		OdGiCalculateNormalCallback	pCallback = NULL ) const

pure virtual

Calculates vertex average normals for the shell.

Parameters

normals	[out] An array that stores the calculation results (normals are represented with <exref target="https://docs.opendesign.com/tkernel/OdGeVector3d.html">OdGeVector3d</exref> objects).
creaseAngelLimit	[in] A crease angle limit.
pCallback	[in] A pointer to the callback function for the custom normal calculation (NULL by default).

Returns: A Boolean value that is equal to true if all calculated normals are non-zero; otherwise, the method returns false.

Remarks: A normal index matches the vertex index in the vertex list. A normal being calculated as normalized is the sum of all face normals that contain a vertex only if all angles between the face normals are less than the specified limit value. Otherwise, the callback function is called to calculate the normal. If the callback function is not specified, a zero normal for the vertex is returned. A normal can be zero when the vertex is isolated or faces are not oriented in the same direction. It can also be zero when the angle between the face normals is greater than the specified limit value and the callback function is not specified.

◆ calculateEdgeVisibilitiesByCreaseAngle() [1/2]

virtual bool OdGiShellToolkit::calculateEdgeVisibilitiesByCreaseAngle	(	OdArray< bool > &	visibilities,
		double	creaseAngle ) const

pure virtual

Calculates the visibility of the shell edges according to the crease angle.

Parameters

visibilities	[out] An array of Boolean values that contain edge visibility flag values. The method fills it with visibility flag values and returns it to the calling subroutine.
creaseAngle	[in] A crease angle limit.

Returns: The true value if the visibility flag values for edges are successfully calculated; otherwise, the method returns false.

Remarks: Sharp and singular edges are visible. Edges with an angle between connected face normals that is greater than the crease angle are visible too. For a single shell, the method generates a ready-to-use array of visibility flag values.

◆ calculateEdgeVisibilitiesByCreaseAngle() [2/2]

virtual bool OdGiShellToolkit::calculateEdgeVisibilitiesByCreaseAngle	(	OdArray< OdGiShellEdgeVisibilityDescription > &	visibilities,
		double	creaseAngle,
		const OdGiShellEdgeVisibilityOptions &	options = OdGiShellEdgeVisibilityOptions() ) const

pure virtual

Calculates the visibility of the shell edges according to the crease angle.

Parameters

visibilities	[out] An array of Boolean values that contain edge visibility flag values. The method fills it with visibility flag values and returns it to the calling subroutine.
creaseAngle	[in] A crease angle limit.
options	[in] <link OdGiShellToolkit::OdGiShellEdgeVisibilityOptions, Visibility generation options>.

Returns: The true value if the visibility flag values for edges are successfully calculated; otherwise, the method returns false.

Remarks: Sharp and singular edges are visible. Edges with an angle between connected face normals that is greater than the crease angle are visible too. For multi-shell cases, the method generates data that contains connections with the original input. When two faces have a common visible edge, its visibility is represented in the output array with a single value if the <link OdGiShellToolkit::OdGiShellEdgeVisibilityOptions::bDuplicateEdges, bDuplicateEdges option> is equal to false; otherwise, the visibility is represented with two values (for AB and BA edges).

◆ calculateFaceNormals()

virtual bool OdGiShellToolkit::calculateFaceNormals ( OdArray< OdGeVector3d > & normals ) const

pure virtual

Calculates face normals for the shell.

Parameters

normals [out] An array that stores face normals (represented with <exref target="https://docs.opendesign.com/tkernel/OdGeVector3d.html">OdGeVector3d</exref> objects).

Returns: A Boolean value that is equal to true if all calculated normals are non-zero; otherwise, the method returns false.

Remarks: This method calculates face normals according to the face plane and the face orientation. A normal index matches the face in the face list. A normal can be zero when the face is degenerated or not flat.

◆ checkFacesOrientation() [1/2]

virtual bool OdGiShellToolkit::checkFacesOrientation ( ) const

pure virtual

Checks the face orientations of a shell.

Returns: The true value when all faces are correctly oriented.

Remarks: The method is not relevant if the shell contains sharp or singular edges.

◆ checkFacesOrientation() [2/2]

virtual bool OdGiShellToolkit::checkFacesOrientation ( const OdGiShellFaceOrientationCallback * pCallback ) const

pure virtual

Checks the face orientations of a shell using a face orientation callback.

Parameters

pCallback [in] A pointer to an <link OdGiShellToolkit::OdGiShellFaceOrientationCallback, OdGiShellFaceOrientationCallback> object.

Returns: The true value when all faces are correctly oriented.

Remarks: The method is relevant when the shell contains sharp or singular edges, and it can be used instead of the <link OdGiShellToolkit::checkFacesOrientation@const, checkFacesOrientation()> method.

◆ clear()

virtual void OdGiShellToolkit::clear ( )

pure virtual

Clears the <link OdGiShellToolkit, shell toolkit> object.

◆ create()

static OdSmartPtr< OdGiShellToolkit > OdGiShellToolkit::create ( )

Returns: A smart pointer to the toolkit implementation.

◆ faceList()

virtual const OdInt32 * OdGiShellToolkit::faceList ( ) const

pure virtual

Requests the face list from the <link OdGiShellToolkit, shell toolkit> object. The face list contains the number of vertices in the first element and indices of vertices that belong to the face in other elements. Vertex indices refer to the elements of the shell vertex array.

Returns: A pointer to the first element of the face list.

◆ faceListSize()

virtual OdUInt32 OdGiShellToolkit::faceListSize ( ) const

pure virtual

Requests the size of the face list from the <link OdGiShellToolkit, shell toolkit> object.

Returns: An unsigned 32-bit integer value that contains the face list size.

◆ filterEdgesByCreaseAngle()

		double	dAngle ) const

pure virtual

Generates a list of edges with a crease angle that exceeds the threshold value.

Parameters

edges	[out] An array of <link OdGiShellToolkit::OdGiShellEdgeDescription, OdGiShellEdgeDescription> objects. The method fills this array with information about edges and returns it to the calling subroutine.
dAngle	[in] The threshold value of the crease angle.

Remarks: The method returns pairs of <link OdGiShellToolkit::OdGiShellEdgeDescription, OdGiShellEdgeDescription> objects; each pair describes the same edge but on different faces.

◆ fixFaceOrientation() [1/2]

virtual bool OdGiShellToolkit::fixFaceOrientation ( bool bRestoreModel = true )

pure virtual

Orients shell faces correctly.

Parameters

bRestoreModel [in] A flag that specifies whether the toolkit should restore the internal shell model.

Returns: The true value when orientation correction is successful; otherwise, it returns false.

Remarks: The method is not relevant if the shell contains sharp or singular edges. After face reorientation, the internal shell model becomes invalid. However, usually face reorientation is the last operation, so restoring the model may not be necessary. Further <link OdGiShellToolkit, toolkit> object usage after the <link OdGiShellToolkit::fixFaceOrientation@bool, fixFaceOrientation>(false) call without calling the <link OdGiShellToolkit::clear, clear()> method generates incorrect results.

◆ fixFaceOrientation() [2/2]

virtual bool OdGiShellToolkit::fixFaceOrientation	(	const OdGiShellFaceOrientationCallback *	pCallback,
		bool	bRestoreModel = true )

pure virtual

Orients shell faces correctly using a face orientation callback.

Parameters

pCallback	[in] A pointer to the <link OdGiShellToolkit::OdGiShellFaceOrientationCallback, OdGiShellFaceOrientationCallback> object.
bRestoreModel	[in] A flag that specifies whether the toolkit should restore the internal shell model.

Returns: The true value when orientation correction is successful; otherwise, it returns false.

Remarks: The method is relevant if the shell contains sharp or singular edges, and it can be used instead of the <link OdGiShellToolkit::fixFaceOrientation@bool, fixFaceOrientation()> method. After face reorientation, the internal shell model becomes invalid. However, usually face reorientation is the last operation, so restoring the model may not be necessary. Further <link OdGiShellToolkit, toolkit> object usage after the <link OdGiShellToolkit::fixFaceOrientation@bool, fixFaceOrientation>(false) call without calling the <link OdGiShellToolkit::clear, clear()> method generates incorrect results.

◆ getIncorrectOrientedFaces() [1/2]
