Detailed Description

Shape nodekit class.

[3] The program prints a diagram of the scene graph and a table with information about each part.

New nodes in this subclass are: materialBinding, normalBinding, and textureCoordinateBinding

A parent node that manages a collection of child nodes into a unit with the following structure:

this ----------------| | "topSeparator" "callbackList" | --------------------------------------------------------------- | | | | | | | | "pickStyle" | "transform" | | | | | "appearance" "texture2Transform" | | | | | | "localTransform" | | | | | | "shapeSeparator" | | | | | "shape" | "childList" --------------------------------- | "materialBinding" "normalBinding" "textureCoordinateBinding" "shapeHints" "coordinate3" "coordinate4" "normal" "textureCoordinate2" "textureCoordinateFunction" "profileCoordinate2" "profileCoordinate3" "profileList"

A nodekit that is used for creating a shape (i.e. geometry). SoShapeKit is derived from SoSeparatorKit and SoBaseKit, and thus inherits all the parts defined by these classes.

Furthermore, SoShapeKit adds numerous parts that can be used to define a variety of shape objects, a localTransform part, and of course a shape part.

All of the property nodes requires to define any of the Inventor shapes are included as parts in this class. Not all of these parts (nodes) are needed for any one type of shape. For example, if you set the shape part to be an SoSphere node, then it is not necessary to create a profileCoordinate3 part since it will be ignored in drawing the sphere. (And the unneeded parts will not be created, so there is no performance penalty for using this class of node.

This class contains two private parts. They are both SoSeparator nodes. One of them sits just below the nodekit itself, and serves to contain all properties within this nodekit from affecting nodes that come after this nodekit. The second separator sits above the shape part, and serves to cache the shape even when the transform, localTransform, or appearance parts are changing.

Parts
shapeSeparator
This is a private part. The parent node of the actual shape part. It is a SoSeparator and is NULL by default, but is created automatically if necessary.
materialBinding
An SoMaterialBinding node that can be used to set the material binding for the shape. This part is NULL by default, but is created automatically if necessary.
normalBinding
An SoNormalBinding node that can be used to set the normal binding for the shape. This part is NULL by default, but is created automatically if necessary.
textureCoordinateBinding
An SoTextureCoordinateBinding node that can be used to set the texture coordinate binding for the shape. This part is NULL by default, but is created automatically if necessary.
shapeHints
An SoShapeHints node that can be used to set the shape hints for the shape. This part is NULL by default, but is created automatically if necessary.
coordinate3
An SoCoordinate3 node that can be used to set the 3D coordinates for a vertex-based shape. This part is NULL by default, but is created automatically if necessary.
coordinate4
An SoCoordinate4 node that can be used to set the 4D coordinates for a NURBS shapes. This part is NULL by default, but is created automatically if necessary.
normal
An SoNormal node that can be used to set the normal vectors for a vertex-based shape. This part is NULL by default, but is created automatically if necessary.
textureCoordinate2
An SoTextureCoordinate2 node that can be used to set the texture coordinates for a vertex-based shape. This part is NULL by default, but is created automatically if necessary.
textureCoordinateFunction
An SoTextureCoordinateFunction node that can be used to set the a procedural texture coordinates function for a vertex-based shape. This part is NULL by default, but is created automatically if necessary.
profileCoordinate2
An SoProfileCoordinate2 node that can be used to set the 2D profile coordinates for a shape that uses them, (e.g., SoText3). This part is NULL by default, but is created automatically if necessary.
profileCoordinate3
An SoProfileCoordinate3 node that can be used to set the 3D profile coordinates for a shape that uses them, (e.g., SoSoNURBSCurve). This part is NULL by default, but is created automatically if necessary.
profileList
An SoProfileList node that can be used to set the profile curve for a shape that uses them, (e.g., SoNurbsCurve). This part is NULL by default, but is created automatically if necessary.
localTransform
An SoTransform node that can be used to set a local tranformation on the shape. This part is NULL by default, but is created automatically if necessary.
shape
This is the part which specifies the actual shape node. This can be any node derived from SoShape By default, an SoCube is created. It is important to set all of the appropriate parts within this nodekit to suit the type of SoShape that is used. For example, if the shape part is set to an SoFaceSet, then the coordinate3 shape and probably the normal shape would be set as well. See the reference page of the shape used for details on which other nodes are necessary.

static void SoShapeKit::initClass ( ) [static]

Reimplemented from SoSeparatorKit.

virtual void SoShapeKit::setDefaultOnNonWritingFields ( ) [protected, virtual]

Calls setDefault(TRUE) on the shapeSeparator. Note that this may be overriden later by basekit if, for example, topSeparator lies on a path that is being written out.
