Detailed Description

The SoVertexProperty class collects the functionality of various appearance nodes.

Instead of reading data from the current state stack of the scene graph traversal, nodes inheriting SoVertexShape can be set up with an SoVertexProperty node in the SoVertexShape::vertexProperty field. Coordinates, normals, texture coordinates and material / color information will then be fetched from the vertex shape's SoVertexProperty node instead of from the state stack.

The SoVertexProperty node provides fields for duplicating the functionality of all these other Inventor node types: SoCoordinate3, SoTextureCoordinate2, SoTextureCoordinate3, SoNormal, SoPackedColor, SoMaterialBinding and SoNormalBinding.

The SoVertexProperty node was introduced fairly late in the design of the Inventor API by SGI. The idea behind it was to provide a means to specify the necessary data for vertex shape derived nodes which would be more efficient to work with than fetching the data from the traversal state stack.

In practice, the effect is not at all very noticeable. Since the use of SoVertexProperty nodes in the SoVertexShape::vertexProperty field somewhat breaks with the basic design of the Open Inventor API (the SoVertexProperty data is not pushed to the traversal state stack), you might be better off design-wise by using the usual mechanisms, i.e. by setting up the individual nodes SoVertexProperty "collects".

One of the drawbacks will for instance be that it is not possible to share parts of the SoVertexProperty node between several shapes, which is something that can easily be done when setting up individual state changing nodes in the scene graph.

FILE FORMAT/DEFAULTS:

VertexProperty {
    vertex [  ]
    normal [  ]
    texCoord [  ]
    orderedRGBA [  ]
    texCoord3 [  ]
    normalBinding PER_VERTEX_INDEXED
    materialBinding OVERALL
}

Member Function Documentation

callback()

void SoVertexProperty::callback ( SoCallbackAction * action )

virtual

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

doAction()

void SoVertexProperty::doAction ( SoAction * action )

virtual

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

getBoundingBox()

void SoVertexProperty::getBoundingBox ( SoGetBoundingBoxAction * action )

virtual

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoNode.

getClassTypeId()

SoType SoVertexProperty::getClassTypeId ( void )

static

This static method returns the SoType object associated with objects of this class.

getFieldData()

const SoFieldData * SoVertexProperty::getFieldData ( void ) const

protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

getFieldDataPtr()

const SoFieldData ** SoVertexProperty::getFieldDataPtr ( void )

staticprotected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Returns the SoFieldData class which holds information about fields in this node.

getPrimitiveCount()

void SoVertexProperty::getPrimitiveCount ( SoGetPrimitiveCountAction * action )

virtual

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoNode.

getTypeId()

SoType SoVertexProperty::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Implements SoBase.

GLRender()

void SoVertexProperty::GLRender ( SoGLRenderAction * action )

virtual

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from SoNode.

notify()

void SoVertexProperty::notify ( SoNotList * l )

protectedvirtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoNode.

pick()

void SoVertexProperty::pick ( SoPickAction * action )

virtual

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

Member Data Documentation

materialBinding

SoSFEnum SoVertexProperty::materialBinding

Defines how to bind the color values specified in the SoVertexProperty::orderedRGBA set to the parts of the "owner" shape. Must be one of the values in the SoVertexProperty::Binding enum.

Default value of the field is SoVertexProperty::OVERALL.

SoMaterialBinding

normal

SoMFVec3f SoVertexProperty::normal

This field defines a set of normal vectors in the same manner as SoNormal::vector. By default the field contains no vectors.

SoNormal

normalBinding

SoSFEnum SoVertexProperty::normalBinding

Defines how to bind the normals specified in the SoVertexProperty::normal set to the parts of the "owner" shape. Must be one of the values in the SoVertexProperty::Binding enum.

Default value of the field is SoVertexProperty::PER_VERTEX_INDEXED.

See also

SoNormalBinding

orderedRGBA

SoMFUInt32 SoVertexProperty::orderedRGBA

A set of "packed" 32-bit diffuse color plus transparency values. Works in the same manner as the SoPackedColor::orderedRGBA field.

By default the field has no data.

SoPackedColor

texCoord

SoMFVec2f SoVertexProperty::texCoord

Same functionality as SoTextureCoordinate2::point. By default the field contains no coordinates.

See also

SoTextureCoordinate2

texCoord3

SoMFVec3f SoVertexProperty::texCoord3

Same functionality as SoTextureCoordinate3::point. By default the field contains no coordinates.

Coin 2.0

TGS Inventor 2.6

textureUnit

SoMFInt32 SoVertexProperty::textureUnit

The texture unit(s) for the texture coordinates. By default this field contains one value, 0, and texture coordinates are then sent to texture unit 0. It's possible to supply multiple values in this field, and the texture coordinates in texCoord or texCoord3 will then be split into those units. The first totalnum/numunits coordinates will be sent to the first unit specified, the next totalnum/numunits coordinates will be sent to the second unit in this field, etc.

Coin 4.0

vertex

SoMFVec3f SoVertexProperty::vertex

This field sets up vertex coordinates in the same manner as SoCoordinate3::point.

By default the field contains no coordinates.
