Detailed Description

MeshViz Representation of vectors data of a surface mesh.

Class to build a vectors field on a surface mesh. This class handles all vectors attributes. A vector is represented by an arrow made of 3 parts, the body, the start-shape and the end-shape. The body is a line or a cylinder starting from a node of the mesh. The start-shape is a pattern drawn at the node position. The end-shape is a pattern drawn at the other extremity of the body. Several type of pattern can be used to draw the shape. The 3 parts can be scaled and colored according to the value of the different fields of the class.

The current mesh is used for the representation of vectors. See PoMesh for more explanations about the current mesh. The vectors of the mesh to be
drawn, are defined by the method addVecsSet of the current mesh (see PoMeshProperty, PbMesh or PbMesh2D), and by the field PoMesh::vecsIndex. The node of the mesh are used as start point of the representation of the vectors.

    ◆ bodyColoringType

    SoSFEnum PoMesh2DVec::bodyColoringType

    coloring method of the body.


    If bodyColoringType = CONSTANT_COLOR, each vector has the same body color, which is the last found during the scene graph traversal.

    If bodyColoringType = MODULE_MAPPING_COLOR, the body's color of a vector depends on its module, and by using the current module-data-mapping (see PoMesh for explanation of the current module-data-mapping).

    If bodyColoringType = SCALAR_MAPPING_COLOR, the body's color of a vector depends on the scalar value at the mesh node used as the start point of the body. In this case, the current data-mapping is used to compute the color in relation to the scalar-value (see PoMesh for more explanations about the current data-mapping). Use enum ArrowColoringType.

    Definition at line 294 of file PoMesh2DVec.h.

    ◆ bodyLengthFactor

    ◆ bodyLengthType

    SoSFEnum PoMesh2DVec::bodyLengthType

    If bodyLengthType = CONSTANT_LENGTH, each vector has the same body length = bodyLengthFactor .

    If bodyLengthType = RELATIVE_LENGTH, the body length of a vector is bodyLengthFactor * vector-module.

    Definition at line 255 of file PoMesh2DVec.h.

    ◆ bodyRadiusFactor

    SoSFFloat PoMesh2DVec::bodyRadiusFactor

    Radius (or radius multiplicative factor) of the cylinder.

    Definition at line 275 of file PoMesh2DVec.h.

    ◆ bodyRadiusType

    SoSFEnum PoMesh2DVec::bodyRadiusType

    Defines type of method to compute the cylinder's radius.

    If bodyRadiusType = CONSTANT_RADIUS, each vector has the same body radius = bodyRadiusFactor . If bodyRadiusType = RELATIVE_RADIUS, the body radius of a vector is bodyRadiusFactor * vector-module. The body radius is either a line-width or a cylinder-radius depending on the field's value bodyShape.

    Definition at line 270 of file PoMesh2DVec.h.

    ◆ bodyShape

    SoSFEnum PoMesh2DVec::bodyShape

    Type of shape (no body, line, cylinder) used to draw the body.

    Definition at line 248 of file PoMesh2DVec.h.

    ◆ density

    If eliminationStatus = TOO_SMALL, the vectors which module is lower than minLength are not drawn.

    If eliminationStatus = TOO_LONG, the vectors which module is greater than maxLength are not drawn. If eliminationStatus = TOO_SMALL_OR_LONG, the vectors which module is lower than minLength or greater than maxLength are not drawn. If eliminationStatus = NONE, each vector selected by the density filter is drawn.

    Definition at line 226 of file PoMesh2DVec.h.

    ◆ endArrowColoringType

    SoSFEnum PoMesh2DVec::endArrowColoringType

    Coloring method of the end shape.

    If endArrowColoringType = CONSTANT_COLOR, each vector has the same end-arrow's color, which is the last found during the scene graph traversal.

    If endArrowColoringType = MODULE_MAPPING_COLOR, the end-arrow's color of a vector depends on its module, and by using the current module-data- mapping (see PoMesh for explanation of the current module-data-mapping).

    If endArrowColoringType = SCALAR_MAPPING_COLOR, the end-arrow's color of a vector depends on the scalar value at the mesh node used as the end point of the end-arrow. In this case, the current data-mapping is used to compute the color in relation to the scalar-value (see PoMesh for more explanations about the current data-mapping).

    ◆ endArrowHeightFactor

    SoSFFloat PoMesh2DVec::endArrowHeightFactor

    Height (or Height multiplicative factor) of the arrow shape.

    Definition at line 365 of file PoMesh2DVec.h.

    ◆ endArrowHeightType

    SoSFEnum PoMesh2DVec::endArrowHeightType

    Defines the type of method to compute the arrow height.

    If endArrowHeightType = CONSTANT_HEIGHT, each vector has the same end-shape height = endArrowHeightFactor . If endArrowHeightType = RELATIVE_ HEIGHT, the end-shape height of a vector is endArrowHeightFactor * body's length.

    Definition at line 360 of file PoMesh2DVec.h.

    ◆ endArrowRadiusFactor

    SoSFFloat PoMesh2DVec::endArrowRadiusFactor

    The end-arrow's radius is end-arrow's height * endArrowRadiusFactor.

    Definition at line 370 of file PoMesh2DVec.h.

    ◆ endArrowShape

    SoSFEnum PoMesh2DVec::endArrowShape

    Type of shape to be drawn at the end point of the body.

    If endArrowShape = NO_SHAPE, the end-shape of each vector is invisible.

    Definition at line 351 of file PoMesh2DVec.h.

    ◆ maxLength

    SoSFFloat PoMesh2DVec::maxLength

    Maximum length of the vector to be drawn.

    Only used when eliminationStatus is TOO_LONG or TOO_SMALL_OR_LONG

    Definition at line 238 of file PoMesh2DVec.h.

    ◆ minLength

    SoSFFloat PoMesh2DVec::minLength

    Minimum length of the vector to be drawn.

    Only used when eliminationStatus is TOO_SMALL or TOO_SMALL_OR_LONG

    Definition at line 232 of file PoMesh2DVec.h.

    ◆ startArrowColoringType

    SoSFEnum PoMesh2DVec::startArrowColoringType

    Coloring method of the start shape.

    If startArrowColoringType = CONSTANT_COLOR, each vector has the same start-arrow's color, which is the last found during the scene graph traversal.

    If startArrowColoringType = MODULE_MAPPING_COLOR, the start-arrow's color of a vector depends on its module, and by using the current module-data- mapping (see PoMesh for explanation of the current module-data-mapping).

    If startArrowColoringType = SCALAR_MAPPING_COLOR, the start-arrow's color of a vector depends on the scalar value at the mesh node used as the start point of the start-arrow. In this case, the current data-mapping is used to compute the color in relation to the scalar-value (see PoMesh for more explanations about the current data-mapping).

    ◆ startArrowHeightFactor

    SoSFFloat PoMesh2DVec::startArrowHeightFactor

    Height (or Height multiplicative factor) of the arrow shape.

    ◆ startArrowHeightType

    SoSFEnum PoMesh2DVec::startArrowHeightType

    Defines the type of method to compute the arrow height.

    If startArrowHeightType = CONSTANT_HEIGHT, each vector has the same start-shape height = startArrowHeightFactor . If startArrowHeightType = RELATIVE_ HEIGHT, the end-shape height of a vector is startArrowHeightFactor * body's length.

    ◆ startArrowRadiusFactor

    SoSFFloat PoMesh2DVec::startArrowRadiusFactor

    The start-arrow's radius is start-arrow's height * startArrowRadiusFactor.

    Definition at line 323 of file PoMesh2DVec.h.

    ◆ startArrowShape

    SoSFEnum PoMesh2DVec::startArrowShape

    Type of shape to be drawn at the start point of the body.

    If startArrowShape = NO_SHAPE, the start-shape of each vector is invisible.
