Creates a scene graph containing beveled shapes.
This action traverses a scene graph or paths, looking for shapes to bevel, then creating another scene graph containing the beveled shapes (in the form of SoCoordinate3 and SoIndexedFaceSet nodes). Typically it is applied to a subgraph that contains only a single shape.
SoBevelAction does not take into consideration PER_FACE or PER_VERTEX materials. Therefore, the shapes to be beveled should have a uniform material (SoMaterialBinding::OVERALL).
It works like other actions, but does not modify the source scene graph. The scene graph containing beveled shapes can be accessed by calling getSceneGraph() after applying the action.
The methods setAngle(), setRadius(), and enableAbsoluteRadius() set the default behavior of the beveling of the shapes this action will be applied to. If bevel property values have been set by the SoBevelProperty node, they are used. Otherwise, the values set by these methods are used.

SoBevelAction::SoBevelAction | ( | ) |
Constructor.
|
virtual |
Destructor.
|
virtual |
Initiates an action on the graph defined by a list of paths.
TRUE can be passed for the obeysRules flag if the given path list has the following 4 properties:
These rules will be obeyed by path lists returned by picking and by searches for non-group nodes.
Reimplemented from SoAction.
|
virtual |
Initiates an action on the graph defined by a node.
Warning: Most actions call ref() on the node before traversing the scene graph, then call unref() after traversal. If the node's reference count was zero (the default), the call to apply() will cause it to be destroyed.

Sets the absolute radius flag.
If TRUE, the radius value is absolute. Otherwise the radius is a value between 0.0 and 1.0; the real radius corresponding is max * radius , where max is the length of the longest edge of the current shape to be beveled. The default is FALSE.
If TRUE, a coplanar test is performed on each shape before beveling it.
This test combines contiguous coplanar faces into one larger face because the bevel method will not work properly on contiguous coplanar faces.
If FALSE, each shape is assumed not to have contiguous coplanar faces. This provides better performance because the coplanar test is not performed.
It is recommended that you turn off this test only if the shapes to be beveled do not contain contiguous coplanar faces. Default value is TRUE.
If TRUE, examine each shape to bevel, removing duplicate faces if found.
As this test is time consuming, it can be turned on/off depending on whether the shapes to be beveled contain duplicate faces or not. If a shape contains duplicate faces the test is off, no beveling will be performed on the shape. Default value is FALSE.
If TRUE, each shape to bevel is re-ordered so that each face is oriented like the first face of the shape.
This test is not time consuming. However, it may be desirable to disable this test when it is not needed. Default value is TRUE.

SbBool SoBevelAction::isAbsoluteRadiusEnabled | ( | ) | const |
