Constructor & Destructor Documentation

◆ EMesh() [1/5]

eVision::Easy3D::EMesh::EMesh ( )

Creates an EMesh object.

◆ EMesh() [2/5]

eVision::Easy3D::EMesh::EMesh	(	const eVision::Easy3D::EPointCloud &	pointCloud,
		const std::vector< int32_t > &	triangleIndexes )

Creates an EMesh object.

Parameters

pointCloud	A point cloud
triangleIndexes	The triangle mesh is a list of indexes, referring to the array contained in "pointCloud".

A triangle is defined by 3 indexes (T1a T1b T1c T2a T2b T2c T3a ....). Index values must be in [0, N[ with N the number of points in the EPointCloud. The triangle index array size is a multiple of 3.

◆ EMesh() [3/5]

eVision::Easy3D::EMesh::EMesh	(	const eVision::Easy3D::EPointCloud &	pointCloud,
		const std::vector< int32_t > &	triangleIndexes,
		const std::vector< eVision::Easy3D::E3DPoint > &	normals )

Creates an EMesh object.

Parameters

pointCloud	A point cloud
triangleIndexes	The triangle mesh is a list of indexes, referring to the array contained in "pointCloud".

A triangle is defined by 3 indexes (T1a T1b T1c T2a T2b T2c T3a ....). Index values must be in [0, N[ with N the number of points in the EPointCloud. The triangle index array size is a multiple of 3.

Parameters

normals Normals of each of the faces of the mesh. Must be the third of the size of "triangleIndexes".

If not provided, they will be computed automatically from the faces by assuming the vertices are listed in counter-clock-wise order from outside (which is the convention used by the stl file format).

◆ EMesh() [4/5]

eVision::Easy3D::EMesh::EMesh ( const eVision::Easy3D::EMesh & other )

Creates an EMesh object.

Parameters

other Another EMesh.

◆ ~EMesh()

eVision::Easy3D::EMesh::~EMesh	(		)
throw	(	)

◆ EMesh() [5/5]

eVision::Easy3D::EMesh::EMesh ( CppWrapperInternal::InternalConstructor )

Member Function Documentation

◆ Clear()

void eVision::Easy3D::EMesh::Clear ( )

Empties the Mesh.

◆ ComputePlaneBehind() [1/2]

eVision::Easy3D::E3DPlane eVision::Easy3D::EMesh::ComputePlaneBehind ( eVision::Easy3D::E3DPoint normal ) const

Returns the E3DPlane with given normal on which the EMesh lays. This is useful when projecting an EMesh on an EZMap.

Parameters

normal The normal of the plane.

◆ ComputePlaneBehind() [2/2]

eVision::Easy3D::E3DPlane eVision::Easy3D::EMesh::ComputePlaneBehind	(	eVision::Easy3D::E3DPoint	normal,
		float	margin ) const

Returns the E3DPlane with given normal on which the EMesh lays. This is useful when projecting an EMesh on an EZMap.

Parameters

normal	The normal of the plane.
margin	Let P be the plane, A point of the EMesh closest to P and B the of the EMesh furthest to B. margin = dist(P, A) / dist(P, B). Must be positive. Default: 0.02.

◆ GetNormals()

const void * eVision::Easy3D::EMesh::GetNormals ( ) const

Returns a pointer to the array (of E3DPoint) representing the list of normals. If the EMesh object has no triangle mesh data, this method returns NULL.

◆ GetPointCloud()

const eVision::Easy3D::EPointCloud & eVision::Easy3D::EMesh::GetPointCloud ( ) const

Returns the point cloud of the EMesh object.

◆ GetTriangleCount()

int32_t eVision::Easy3D::EMesh::GetTriangleCount ( ) const

Returns the number of triangles.

If the EMesh object has no triangle mesh data, the method returns 0.

◆ GetTriangleIndexes()

const void * eVision::Easy3D::EMesh::GetTriangleIndexes ( ) const

Returns a pointer to the index array (an array of 32 bit signed integers) representing the list of triangles. Indexes are referring to the array of E3DPoint.

A triangle is defined by 3 indexes (T1a T1b T1c T2a T2b T2c T3a ....). The triangle index array size is a multiple of 3.

Index values must be in [0, N[ where N is the number of points in the point cloud. If the EMesh object has no triangle mesh data, this method returns NULL.

◆ Load() [1/2]

void eVision::Easy3D::EMesh::Load ( const std::string & path )

Parameters

path	The file path.

◆ Load() [2/2]

void eVision::Easy3D::EMesh::Load ( eVision::ESerializer * serializer )

Loads the EMesh. Supported formats are eVision proprietary and STL. The given ESerializer must have been created for reading.

Parameters

serializer The serializer.

◆ LoadSTL()

void eVision::Easy3D::EMesh::LoadSTL ( const std::string & path )

Loads a triangle mesh from an STL file.

Parameters

path	The path to the STL file.

◆ operator=()

eVision::Easy3D::EMesh & eVision::Easy3D::EMesh::operator= ( const eVision::Easy3D::EMesh & other )

Assignment operator.

Parameters

other The other EMesh that we will copy into this one.

◆ Save() [1/2]

void eVision::Easy3D::EMesh::Save ( const std::string & path )

Saves the EMesh. Supported formats are eVision proprietary and STL. The given ESerializer must have been created for writing.

Parameters

path	The file path.

◆ Save() [2/2]

void eVision::Easy3D::EMesh::Save ( eVision::ESerializer * serializer )

Saves the EMesh. Supported formats are eVision proprietary and STL. The given ESerializer must have been created for writing.

Parameters

serializer The ESerializer object that is written to.

◆ SaveSTL() [1/2]

void eVision::Easy3D::EMesh::SaveSTL ( const std::string & path ) const
