Constructor & Destructor Documentation

__init__() [1/4]

None eVision.Easy3D.EMesh.__init__

(

self

)

Creates an eVision.Easy3D.EMesh object.

__init__() [2/4]

None eVision.Easy3D.EMesh.__init__	(		self,
		eVision.Easy3D.EPointCloud	pointCloud,
		list[int]	triangleIndexes )

Creates an eVision.Easy3D.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 eVision.Easy3D.EPointCloud. The triangle index array size is a multiple of 3.

__init__() [3/4]

None eVision.Easy3D.EMesh.__init__	(		self,
		eVision.Easy3D.EPointCloud	pointCloud,
		list[int]	triangleIndexes,
		list[eVision._eVision.Easy3D.E3DPoint]	normals )

Creates an eVision.Easy3D.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 eVision.Easy3D.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).

__init__() [4/4]

None eVision.Easy3D.EMesh.__init__	(		self,
		eVision.Easy3D.EMesh	other )

Creates an eVision.Easy3D.EMesh object.

Parameters

other

Another eVision.Easy3D.EMesh.

Member Function Documentation

Clear()

None eVision.Easy3D.EMesh.Clear

(

self

)

Empties the Mesh.

ComputePlaneBehind() [1/2]

eVision.Easy3D.E3DPlane eVision.Easy3D.EMesh.ComputePlaneBehind	(		self,
		eVision.Easy3D.E3DPoint	normal )

Returns the eVision.Easy3D.E3DPlane with given normal on which the eVision.Easy3D.EMesh lays.

This is useful when projecting an eVision.Easy3D.EMesh on an eVision.Easy3D.EZMap.

Parameters

normal

ComputePlaneBehind() [2/2]

eVision.Easy3D.E3DPlane eVision.Easy3D.EMesh.ComputePlaneBehind	(		self,
		eVision.Easy3D.E3DPoint	normal,
		float	margin )

Returns the eVision.Easy3D.E3DPlane with given normal on which the eVision.Easy3D.EMesh lays.

This is useful when projecting an eVision.Easy3D.EMesh on an eVision.Easy3D.EZMap.

Parameters

normal	The normal of the plane.
margin	Let P be the plane, A point of the eVision.Easy3D.EMesh closest to P and B the of the eVision.Easy3D.EMesh furthest to B. margin = dist(P, A) / dist(P, B). Must be positive. Default: 0.02.

Load() [1/2]

None eVision.Easy3D.EMesh.Load	(		self,
		eVision.ESerializer | None	serializer )

Load() [2/2]

None eVision.Easy3D.EMesh.Load	(		self,
		str	path )

Loads the eVision.Easy3D.EMesh.

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

Parameters

path	The file path.

LoadSTL()

None eVision.Easy3D.EMesh.LoadSTL	(		self,
		str	path )

Loads a triangle mesh from an STL file.

Parameters

path	The path to the STL file.

Normals()

ctypes.c_void_p eVision.Easy3D.EMesh.Normals

(

self

)

Returns a pointer to the array (of eVision.Easy3D.E3DPoint) representing the list of normals.

If the eVision.Easy3D.EMesh object has no triangle mesh data, this method returns NULL.

PointCloud()

eVision.Easy3D.EPointCloud eVision.Easy3D.EMesh.PointCloud

(

self

)

Returns the point cloud of the eVision.Easy3D.EMesh object.

Save() [1/2]

None eVision.Easy3D.EMesh.Save	(		self,
		eVision.ESerializer | None	serializer )

Saves the eVision.Easy3D.EMesh.

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

Parameters

serializer

The eVision.ESerializer object that is written to.

Save() [2/2]

None eVision.Easy3D.EMesh.Save	(		self,
		str	path )

Saves the eVision.Easy3D.EMesh.

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

Parameters

path	The file path.

SaveSTL() [1/2]

None eVision.Easy3D.EMesh.SaveSTL	(		self,
		str	path )

Saves the triangle mesh to an STL file.

Parameters

path	The path to the STL file.

SaveSTL() [2/2]

None eVision.Easy3D.EMesh.SaveSTL	(		self,
		str	path,
		bool	binary )

Saves the triangle mesh to an STL file.

Parameters

path	The path to the STL file.
binary	Optional parameter, activates the binary file format (default is true).

TriangleCount()

int eVision.Easy3D.EMesh.TriangleCount

(

self

)

Returns the number of triangles.

If the eVision.Easy3D.EMesh object has no triangle mesh data, the method returns 0.

TriangleIndexes()

ctypes.c_void_p eVision.Easy3D.EMesh.TriangleIndexes

(

self

)

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 eVision.Easy3D.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 eVision.Easy3D.EMesh object has no triangle mesh data, this method returns NULL.
