The ObjectAttributes type exposes the following members.
Initializes a new instance of the ObjectAttributes class
Initializes a new instance of the ObjectAttributes class
Gets or sets an object's casts shadows property, or whether or not an object casts shadows on other objects and a ground plane.
The color used to display an object is specified in one of three ways. If ColorSource is ON::color_from_layer, then the object's layer ON_Layer::Color() is used. If ColorSource is ON::color_from_object, then value of m_color is used. If ColorSource is ON::color_from_material, then the diffuse color of the object's render material is used. See ON_3dmObjectAttributes::MaterialSource() to determine where to get the definition of the object's render material.
Returns or sets the per-object render meshing parameters, which controls the object's render mesh density. If this property is null, then the object uses the document's render meshing parameters. To remove the per-object render meshing parameters, set this property to null.
Gets all object decals associated with this object.
Display order used to force objects to be drawn on top or behind each other. Larger numbers draw on top of smaller numbers.
0 = draw object in standard depth buffered order
<0 = draw object behind "normal" draw order objects
>0 = draw object on top of "normal" draw order objects
Indicates if this object has been disposed or the document it originally belonged to has been disposed.(Inherited from CommonObject.)
number of groups object belongs to.
A mapping from any plug-in source is associated with these attributes Need to do this here to respond correctly to ModifyObjectAttributes event
Gets true if this class has any custom information attached to it through UserData.(Inherited from CommonObject.)
Use this query to determine if an object is part of an instance definition.
Tests an object to see if it is valid.(Inherited from CommonObject.)
Gets or sets an associated layer index.
Layer definitions in an OpenNURBS model are stored in a layer table. The layer table is conceptually an array of ON_Layer classes. Every OpenNURBS object in a model is on some layer. The object's layer is specified by zero based indices into the ON_Layer array.
Gets or sets the linetype index.
Linetype definitions in an OpenNURBS model are stored in a linetype table. The linetype table is conceptually an array of ON_Linetype classes. Every OpenNURBS object in a model references some linetype. The object's linetype is specified by zero based indices into the ON_Linetype array.
Index 0 is reserved for continuous linetype (no pattern).
The Linetype used to display an object is specified in one of two ways. If LinetypeSource is ON::linetype_from_layer, then the object's layer ON_Layer::Linetype() is used. If LinetypeSource is ON::linetype_from_object, then value of m_linetype is used.
Gets or sets the material index.
If you want something simple and fast, set the index of the rendering material.
If you are developing a high quality plug-in renderer, and a user is assigning a custom render material to this object, then add rendering material information to the MaterialRefs dictionary. Note to developers: As soon as the MaterialRefs dictionary contains items rendering material queries slow down. Do not populate the MaterialRefs dictionary when setting the MaterialIndex will take care of your needs.
Determines if the simple material should come from the object or from it's layer. High quality rendering plug-ins should use m_rendering_attributes.
An object must be in one of three modes: normal, locked or hidden. If an object is in normal mode, then the object's layer controls visibility and selectability. If an object is locked, then the object's layer controls visibility by the object cannot be selected. If the object is hidden, it is not visible and it cannot be selected.
Gets or sets an object optional text name.
More than one object in a model can have the same name and some objects may have no name.
If ON::color_from_object == ColorSource, then color is the object's display color.
Used to indicate an object has a decoration (like an arrowhead on a curve)
Every object has a Guid (globally unique identifier, also known as UUID, or universally unique identifier). The default value is Guid.Empty.
When an object is added to a model, the value is checked. If the value is Guid.Empty, a new Guid is created. If the value is not null but it is already used by another object in the model, a new Guid is created. If the value is not Guid.Empty and it is not used by another object in the model, then that value persists. When an object is updated, by a move for example, the value of ObjectId persists.
This value is the same as the one returned by object.Id.
The mapping channel id to use when calling MappingChannel to retrieve the OCS mapping if there is one.
If plot_color_from_object == PlotColorSource, then PlotColor is the object's plotting color.
The color used to plot an object on paper is specified in one of three ways. If PlotColorSource is ON::plot_color_from_layer, then the object's layer ON_Layer::PlotColor() is used. If PlotColorSource is ON::plot_color_from_object, then value of PlotColor() is used.
Plot weight in millimeters. =0.0 means use the default width <0.0 means don't plot (visible for screen display, but does not show on plot)
Gets or sets an object's receives shadows property, or whether or not an object receives shadows from other objects.
Sets the render material for the object - higher level function for setting MaterialSource and MaterialIndex
Starting with V4, objects can be in either model space or page space. If an object is in page space, then ViewportId is not nil and identifies the page it is on.
Objects may have an URL. There are no restrictions on what value this URL may have. As an example, if the object came from a commercial part library, the URL might point to the definition of that part.
List of custom information that is attached to this class.(Inherited from CommonObject.)
Dictionary of custom information attached to this class. The dictionary is actually user data provided as an easy to use sharable set of information.(Inherited from CommonObject.)
If ViewportId is nil, the object is active in all viewports. If ViewportId is not nil, then this object is only active in a specific view. This field is primarily used to assign page space objects to a specific page, but it can also be used to restrict model space to a specific view.
Gets or sets an object's visibility.
When a surface object is displayed in wireframe, this controls how many isoparametric wires are used. value number of isoparametric wires -1 boundary wires (off) 0 boundary and knot wires 1 boundary and knot wires and, if there are no interior knots, a single interior wire. N>=2 boundary and knot wires and (N+1) interior wires.
Make this object hidden in a given detail
Adds object to the group with specified index by appending index to group list.
If the object is already in group, nothing is changed.
Assigns a parent object and a sub-object index to this.(Inherited from CommonObject.)
Actively reclaims unmanaged resources that this instance uses.(Inherited from CommonObject.)
For derived class implementers.(Inherited from CommonObject.)
This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method.
You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true.
Also, you must call the base virtual method within your overriding method.
Constructs a copy of this ObjectAttributes instance.
If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.(Inherited from CommonObject.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().(Inherited from CommonObject.)
Returns the id of the display mode of an objects. Object display modes are view based. Thus, it is possible to have an object display different in different views.
Returns an array of GroupCount group indices. If GroupCount is zero, then GetGroupList() returns null.
Serves as the default hash function.(Inherited from Object.)
Get list of details that this object is supposed to be hidden in
Populates a System.Runtime.Serialization.SerializationInfo with the data needed to serialize the target object.(Inherited from CommonObject.)
Gets the Type of the current instance.(Inherited from Object.)
Gets a user string.
Gets an independent copy of the collection of (user text key, user text value) pairs attached to this object.
Determines if an object has a display mode override for a given viewport.
Is this object supposed to be hidden in a given detail
Determines if an object is valid. Also provides a report on errors if this object happens not to be valid.(Inherited from CommonObject.)
Creates a shallow copy of the current Object.(Inherited from Object.)
For derived classes implementers.(Inherited from CommonObject.)
Defines the necessary implementation to free the instance from being constant.
Is called when a non-constant operation first occurs.(Inherited from CommonObject.)
By default, objects are drawn using the display mode of the viewport that the object is being drawn in. Setting a specific display mode, instructs Rhino to always use that display mode, regardless of the viewport's mode. This function resets an object to use the viewport's display mode for all viewports.
