Defines an extrusion for a shape.

The following attributes modify an extrusion.

Attribute Description
AutoRotationCenter Determines whether the center of rotation will be the geometric center of the extrusion.
BackDepth Defines the amount of backward extrusion.
Brightness Specifies the amount of brightness of a scene.
Color Defines the color of the extrusion faces.
ColorMode Determines the mode of extrusion color.
Diffusity Defines the amount of diffusion of reflected light from an extruded shape.
Edge Defines the apparent bevel of the extrusion edges.
Ext Defines the default extrusion behavior for graphical editors.
Facet Defines the number of facets used to describe curved surfaces of an extrusion.
ForeDepth Defines the amount of forward extrusion.
LightFace Determines whether the front face of the extrusion will respond to changes in the lighting.
LightHarsh Determines whether the primary light source will be harsh.
LightHarsh2 Determines whether the secondary light source will be harsh.
LightLevel Defines the intensity of the primary light source for the scene.
LightLevel2 Defines the intensity of the secondary light source for the scene.
LightPosition Specifies the position of the primary light in a scene.
LightPosition2 Specifies the position of the secondary light in a scene.
LockRotationCenter Determines whether the rotation of the extruded object is specified by the RotationAngle attribute.
Metal Determines whether the surface of the extruded shape will resemble metal.
On Determines whether an extrusion will be displayed.
Orientation Specifies the vector around which a shape will be rotated.
OrientationAngle Defines the angle that an extrusion rotates around the orientation.
Plane Specifies the plane that is at right angles to the extrusion.
Render Defines the rendering mode of the extrusion.
RotationAngle Specifies the rotation of the object about the x- and y-axes.
RotationCenter Specifies the center of rotation for a shape.
Shininess Defines the concentration of reflected light of an extrusion surface.
SkewAmt Defines the amount of skew of an extrusion.
SkewAngle Defines the angle of skew of an extrusion.
Specularity Defines the specularity of an extruded shape.
Type Defines the way that the shape is extruded.
Viewpoint Defines the viewpoint of the observer.
ViewpointOrigin Defines the origin of the viewpoint within the bounding box of the shape.

 

Remarks

This element must be defined within a Shape element.

In addition, the On attribute must be set to True.

The following is the minimum code needed to produce an extrusion.

   <v:rect style="width:50px;height:50px">
   <v:extrusion on="True"/>
   </v:rect>
