The geometry is stored in some class derived from ON_Geometry and the attributes are stored in an ON_3dmObjectAttributes class. Examples of attributes are object name, object id, display attributes, group membership, layer membership, and so on.
Remarks: 7 January 2003 Dale Lear Derived from ON_Object so ON_UserData can be attached to ON_3dmObjectAttributes.

ON_DEPRECATED unsigned int ApplyParentalControl( const ON_3dmObjectAttributes& parent_attributes, unsigned int control_limits = 0xFFFFFFFF );
ON::object_color_source ON_3dmObjectAttributes::ColorSource | ( | ) | const |
The color used to display an OpenNURBS 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.
const ON_MeshParameters* ON_3dmObjectAttributes::CustomRenderMeshParameters | ( | ) | const |
Returns: Null or a pointer to fragile mesh parameters. If a non-null pointer is returned, copy it and use the copy. DO NOT SAVE THIS POINTER FOR LATER USE. A call to DeleteMeshParameters() will delete the class. DO NOT const_cast the returned pointer and change its settings. You must use either SetMeshParameters() or EnableMeshParameters() to change settings. Remarks: If the value of ON_MeshParameters::m_bCustomSettingsDisabled is true, then do no use these parameters to make a render mesh.
void ON_3dmObjectAttributes::Default | ( | ) |

bool ON_3dmObjectAttributes::FindDisplayMaterialRef | ( | const ON_DisplayMaterialRef & | search_material, |
ON_DisplayMaterialRef * | found_material = nullptr |
||
) | const |
display material references
Description: Searches for a matching display material. For a given viewport id, there is at most one display material. For a given display material id, there can be multiple viewports. If there is a display reference in the list with a nil viewport id, then the display material will be used in all viewports that are not explictly referenced in other ON_DisplayMaterialRefs.
Parameters: search_material - [in] found_material - [out]
If FindDisplayMaterialRef(), the input value of search_material is never changed. If FindDisplayMaterialRef() returns true, the chart shows the output value of display_material. When there are multiple possibilities for a match, the matches at the top of the chart have higher priority.
search_material found_material input value output value
(nil,nil) (nil,did) if (nil,did) is in the list. (nil,did) (vid,did) if (vid,did) is in the list. (nil,did) (nil,did) if (nil,did) is in the list. (vid,nil) (vid,did) if (vid,did) is in the list (vid,nil) (vid,did) if (nil,did) is in the list (vid,did) (vid,did) if (vid,did) is in the list.
Example: ON_UUID display_material_id = ON_nil_uuid; ON_Viewport vp = ...; ON_DisplayMaterialRef search_dm; search_dm.m_viewport_id = vp.ViewportId(); ON_DisplayMaterialRef found_dm; if ( attributes.FindDisplayMaterial(search_dm, &found_dm) ) { display_material_id = found_dm.m_display_material_id; }

Returns: True if successful. (xform is invertable or didn't need to be).
|
overridevirtual |
Description: Uses the destination_manifest to update references to other components. This is typically done when a component's references came from a "source" context and are being updated to the "destination" context. For example, inserting one model into another when index, id, and name conflicts need to be resolved at the time of insertion. Parameters: source_manifest - [in] A manifest of the source context with indices and ids corresponding to the current component references. If this manifest is not available, pass ON_ComponentManifest::Empty. destination_manifest - [in] A manifest of the destination context with indices and ids corresponding to the desired component references. If this manifest is not available, pass ON_ComponentManifest::Empty. manifest_map - [in] A map from the source (current) referenced component index/id values to the destination (desired) component index/id values. Returns: True if successful. False indicates a referenced component was not found in the manifest and the reference was changed to a default value. Example: If this object is an ON_Layer, the line pattern and render material references are updated. If this object is an ON_DimStyle, the text style reference is updated. If this object is an ON_3dmObjectAttributes, the layer, material, line pattern, and group references are updated.

ON_Color ON_3dmObjectAttributes::m_color |
If ON::color_from_object == ColorSource(), then m_color is the object's display color.
int ON_3dmObjectAttributes::m_display_order |
Display order used to force objects to be drawn on top or behind each other 0 = draw object in standard depth buffered order <0 = draw object behind "normal" draw order objects >0 = draw object on top of "noraml" draw order objects Larger number draws on top of smaller number.
ON_SimpleArray<ON_DisplayMaterialRef> ON_3dmObjectAttributes::m_dmref |
int ON_3dmObjectAttributes::m_layer_index |
int ON_3dmObjectAttributes::m_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 indicies into the ON_Linetype array. index 0 is reserved for continuous linetype (no pattern)
int ON_3dmObjectAttributes::m_material_index |
Rendering material: If you want something simple and fast, set m_material_index to the index of the rendering material and ignore m_rendering_attributes. If you are developing a high quality plug-in renderer, and a user is assigning one of your fabulous rendering materials to this object, then add rendering material information to the m_rendering_attributes.m_materials[] array.
Developers: As soon as m_rendering_attributes.m_materials[] is not empty, rendering material queries slow down. Do not populate m_rendering_attributes.m_materials[] when setting m_material_index will take care of your needs.
ON_wString ON_3dmObjectAttributes::m_name |
ON::object_decoration ON_3dmObjectAttributes::m_object_decoration |
Used to indicate an object has a decoration (like an arrowhead on a curve)
ON_Color ON_3dmObjectAttributes::m_plot_color |
If ON::plot_color_from_object == PlotColorSource(), then m_color is the object's display color.
double ON_3dmObjectAttributes::m_plot_weight_mm |
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)
ON_ObjectRenderingAttributes ON_3dmObjectAttributes::m_rendering_attributes |
ON::active_space ON_3dmObjectAttributes::m_space |
Starting with V4, objects can be in either model space or page space. If an object is in page space, then m_viewport_id is not nil and identifies the page it is on.
ON_wString ON_3dmObjectAttributes::m_url |
OpenNURBS 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.
ON_UUID ON_3dmObjectAttributes::m_uuid |
Every OpenNURBS object has a UUID (universally unique identifier). The default value is nullptr. When an OpenNURBS object is added to a model, the value is checked. If the value is nullptr, a new UUID is created. If the value is not nullptr but it is already used by another object in the model, a new UUID is created. If the value is not nullptr 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 m_uuid persists.
ON_UUID ON_3dmObjectAttributes::m_viewport_id |
If m_viewport_id is nil, the object is active in all viewports. If m_viewport_id 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.
int ON_3dmObjectAttributes::m_wire_density |
When a surface object is displayed in wireframe, m_wire_density controls how many isoparametric wires are used.
@table value number of isoparametric wires -1 boundary wires 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
