constructor.

Member Function Documentation

AddFace() [1/2]

void AECGe::Mesh::AddFace	(	const IndexList &	face,
		bool *	bSuccess = 0
	)

Adds a face.

Remarks

If the face is non-convex it will be triangulated.

AddFace() [2/2]

OdUInt32 AECGe::Mesh::AddFace	(	const MeshFace &	face,
		bool	bCheckPlane = true,
		bool *	bSuccess = 0
	)

Adds a face.

Returns

Index of new face.

Remarks

Method triangulates the face if it is non-convex.

AddTriangles()

void AECGe::Mesh::AddTriangles

(

const IndexList &

triangles

)

Adds the list of triangular faces specified by triples of vertex indices.

AddVertex()

OdUInt32 AECGe::Mesh::AddVertex	(	const OdGePoint3d &	ptVertex,
		bool	bUnique = false
	)

Appends new vertex.

Parameters

ptVertex	[in] Vertex to add.
bUnique	[in] If true then method doesn't add duplicate point but the performance is pour. It is faster to add multiple points without this check and then call RemoveSameVertices.

Returns

Index of new vertex.

Remarks

: Does not verify that new vertex is unique.

Such calls should be followed by Normalize call

Append()

void AECGe::Mesh::Append

(

const Mesh &

mMesh

)

Fast append operation.

Remarks

For intersecting meshes this operation is not safe. Invalid mesh will be produced in this case.

Clear()

void AECGe::Mesh::Clear

(

)

Clear mesh contents.

ClearFaces()

void AECGe::Mesh::ClearFaces

(

)

Clear all faces leaving vertex data intact.

Decompose()

void AECGe::Mesh::Decompose

(

std::vector< Mesh > &

aResult

)

const

Returns the array of simple closed meshes.

Remarks

Produces valid result only for closed mesh. If mesh is not closed than at least one of the resulting meshes will be non-closed.

GetEdgeCount()

OdUInt32 AECGe::Mesh::GetEdgeCount

(

)

const

Returns the number of edges.

Remarks

This value is not stored so it is calculated by iterating through all faces.

GetExtents()

void AECGe::Mesh::GetExtents

(

OdGeExtents3d &

extents

)

const

Returns mesh extents.

GetFace() [1/2]

MeshFace & AECGe::Mesh::GetFace

(

OdUInt32

iIndex

)

GetFace() [2/2]

const MeshFace & AECGe::Mesh::GetFace

(

OdUInt32

iIndex

)

const

Returns face by index.

GetFaceCount()

OdUInt32 AECGe::Mesh::GetFaceCount

(

)

const

Returns the number of vertices.

GetVertex()

const OdGePoint3d & AECGe::Mesh::GetVertex

(

OdUInt32

iIndex

)

const

Returns vertex location by index.

GetVertexCount()

OdUInt32 AECGe::Mesh::GetVertexCount

(

)

const

Returns the number of vertices.

GetVolume()

double AECGe::Mesh::GetVolume

(

)

const

Returns mesh volume.

Invert()

void AECGe::Mesh::Invert

(

)

Inverts the mesh.

IsClosed()

bool AECGe::Mesh::IsClosed

(

)

const

Returns whether the mesh is a closed solid body.

IsEmpty()

bool AECGe::Mesh::IsEmpty

(

)

const

Returns true if mesh doesn't contain any faces.

Normalize()

void AECGe::Mesh::Normalize

(

)

Performs several actions for preserving mesh quality.

Remarks

RemoveSameVertices

PerformOperation()

static void AECGe::Mesh::PerformOperation ( FacetModeler::BooleanOperation  eOperation, const Mesh &  mOp1, const Mesh &  mOp2, Mesh &  mResult, bool  bCheckExtents = false  )

static

Performs boolean operation with two meshes.

Parameters

eOperation	[in] Type of boolean operation.
mOp1	[in] First operand.
mOp2	[in] Second operand.
mResult	[in] Result.
bCheckExtents	[in] If true and the extents of two operands do not intersect then fast operation is used.

Remarks

Setting last operand to true is valid only for closed operands.

RegenEdgeVisibilities()

void AECGe::Mesh::RegenEdgeVisibilities

(

)

Marks edges that lie between coplanar faces as invisible.

RemoveEdgeVisibilities()

void AECGe::Mesh::RemoveEdgeVisibilities

(

)

Sets all invisible edges as visible.

RemoveSameVertices()

void AECGe::Mesh::RemoveSameVertices

(

)

Forces only unique vertices to be present in vertex container.

Remarks

O( V * Log(V) )

RemoveTJunctions()

void AECGe::Mesh::RemoveTJunctions

(

)

Splits all edges by all vertices.

SetEdgeVisibilities()

void AECGe::Mesh::SetEdgeVisibilities

(

OdGiVisibility

eVisibility

)

Sets all edge visibilities to specified value.

SetVertex()

void AECGe::Mesh::SetVertex	(	OdUInt32	iIndex,
		const OdGePoint3d &	ptVertex
	)

Sets vertex location by index.

Parameters

iIndex	[in] Vertex index.
ptVertex	[in] Vertex location.

Remarks

This operation is not safe. Planes of the referencing faces become invalid. Some faces may no longer be planar after this operation.

Simplify()

void AECGe::Mesh::Simplify

(

)

SwapFace()

void AECGe::Mesh::SwapFace	(	OdUInt32	iIndex,
		MeshFace &	face
	)

Swaps face with the specified index with the specified one.

Remarks

Used internally.

Transform()

void AECGe::Mesh::Transform

(

const OdGeMatrix3d &

mMatrix

)

Transforms the mesh.

Remarks

If transformation passed to method has negative determinant, then the mesh gets inverted after transformation to preserve volume sign.

Triangulate()

void AECGe::Mesh::Triangulate

(

)

Mesh is converted in a way to hold only triangles.

Vertices()

const std::vector< OdGePoint3d > & AECGe::Mesh::Vertices

(

)

const

Returns the array of vertices.
