Detailed Description

Defines an abstract surface mesh.

A surface mesh is made of polygonal cells that define a 2D or 3D surface. The topology of this mesh is either regular (see derived class PbGrid2D) or irregular (see derived class PbIndexedMesh2D).

Member Enumeration Documentation

◆ ExtrapolationMethod

enum PbMesh2D::ExtrapolationMethod

Specifies the type of extrapolation used by getFaultMesh() when computing values on the fault lines.

Enumerator
USE_ADJACENT_DERIVS	Computes the value at a point of the fault line by using the derivatives at its adjacent nodes.
USE_ADJACENT_VALUES	Computes the value at a point of the fault line as the average values of its adjacent nodes.

Definition at line 89 of file PbMesh2D.h.

Member Function Documentation

◆ addVecsSet()

void PbMesh2D::addVecsSet	(	int	set_index,
		const SbVec2f *	val,
		const SbString &	setName = `""`
	)

Adds a set of 2D vectors on the mesh.

set_index is the index of the set. Note that even if the isDataDuplicated field is FALSE, this set of 2D vectors is always duplicated in a PbMesh2D object. If you do not want to duplicate your vectors set, you must set is_data_duplicated to FALSE in your mesh constructor and use the method PbMesh::addVecsSet().

◆ getArea()

virtual float PbMesh2D::getArea ( ) const

virtual

Gets the area of the mesh.

Implements PbMesh.

Reimplemented in PbParalCartesianGrid2D, and PbRegularCartesianGrid2D.

◆ getBoundingBox()

virtual SbBox2f PbMesh2D::getBoundingBox ( ) const

virtual

Gets the 2D mesh's bounding box.

◆ getFaultMesh() [1/2]

PbMesh2D * PbMesh2D::getFaultMesh	(	int	num_fault_lines,
		const int *	fault_line_sizes,
		const SbVec3f *	coord
	)		const

inline

Same as calling getFaultMesh(num_fault_lines, fault_line_sizes, coord,PbMesh2D::USE_ADJACENT_DERIVS, PbDefinedValue())

Definition at line 155 of file PbMesh2D.h.

◆ getFaultMesh() [2/2]

PbMesh2D * PbMesh2D::getFaultMesh	(	int	num_fault_lines,
		const int *	fault_line_sizes,
		const SbVec3f *	coord,
		ExtrapolationMethod	extrapol_method,
		PbDefinedValue &	definedValue
	)		const

Builds a new mesh by inserting some fault lines in this mesh.

Each point of the fault line is inserted in the new mesh to cut the cells. The resulting mesh contains the fault lines as holes with "null width".

LIMITATIONS: The coordinates of the fault line must not be outside the mesh geometry. Furthemore, this method may not work correctly if the fault lines contain many segments that cross other segments or if some segments are tangent or almost tangent to other segments.

Parameters

num_fault_lines	number of fault lines.
fault_line_sizes	each element in this array is the number of points in each line. For instance, if fault_line_sizes = {3,5}, two fault lines are inserted; the first one has 3 points and the second one has 5 points.
coord	the coordinate of each point of the fault lines. For instance, if fault_line_sizes = {3,5}, coord must contain 8 elements. coord[0] ... coord[2] are the coordinates of the first fault line and coord[3] ... coord[7] are the coordinates of the second fault line. LIMITATION: These coordinates must be inside the mesh.
extrapol_method	type of extrapolation used to compute the nodes values on the fault lines. See ExtrapolationMethod
definedValue	instance of a class that is used to determine if a node has a value that should be considered as "defined" or "undefined". getFaultMesh needs to know this because only adjacent nodes with "defined" values are taken into account when computing the value of a node on the fault line. When all adjacent nodes are "undefined", the value at a point of the fault line is set to PbDefinedValue::getUndef(). The default instance of PbDefinedValue assumes all nodes are "defined" (because PbDefinedValue::operator()() returns always TRUE) and that the "undefined" value is 0 (PbDefinedValue::getUndef() returns 0). PbDefinedValue should be subclassed to change these default behaviors.

◆ getVolume()

virtual float PbMesh2D::getVolume ( ) const

inlinevirtual

Always returns 0.
