SyntaxThe SoTransformProjection type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoTransformProjection | Constructor. |
Methods| Name | Description | |
|---|---|---|
| AddProjection | Add a projection with the given name and id to the list. |
| AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Inherited from SoProjection.) |
| Copy | Calls Copy(false). (Inherited from SoNode.) |
| Copy(Boolean) | Creates and returns an exact copy of the node. |
| CopyFieldValues(SoFieldContainer) | Calls CopyFieldValues(fc, false). (Inherited from SoFieldContainer.) |
| CopyFieldValues(SoFieldContainer, Boolean) | Copies the contents of fc's fields into this object's fields. |
| Dispose |
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.) |
| Distribute | (Inherited from SoNode.) |
| DoAction | (Inherited from SoProjection.) |
| EnableNotify | Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. |
| Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. |
| GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. |
| GetAlternateRep | This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type). |
| GetBoundingBox | (Inherited from SoProjection.) |
| GetCurrentProjectionInfos | Return current projection name and id. |
| GetEventIn | Returns a the eventIn with the given name. |
| GetEventOut | Returns the eventOut with the given name. |
| GetField | Returns a the field of this object whose name is fieldName. |
| GetFieldName | Returns the name of the given field in the fieldName argument. |
| GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetMatrix | (Inherited from SoProjection.) |
| GetName | Returns the name of an instance. |
| GetPrimitiveCount | (Inherited from SoNode.) |
| GetProjection | Return current projection. |
| GetRenderEngineMode | Returns the supported Render engine mode. |
| GetRenderUnitID | (Inherited from SoNode.) |
| GetStringName | (Inherited from SoBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GLRender | (Inherited from SoProjection.) |
| GLRenderBelowPath | (Inherited from SoNode.) |
| GLRenderInPath | (Inherited from SoNode.) |
| GLRenderOffPath | (Inherited from SoNode.) |
| GrabEventsCleanup | (Inherited from SoNode.) |
| GrabEventsSetup | (Inherited from SoNode.) |
| HandleEvent | (Inherited from SoProjection.) |
| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsBoundingBoxIgnoring | This method is used by getBoundingBox action traversal to know if the current node must be traversed or not, ie the bounding should be ignored. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsOverride | Returns the state of the override flag. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Pick | (Inherited from SoProjection.) |
| RayPick | (Inherited from SoProjection.) |
| Search | (Inherited from SoNode.) |
| Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. |
| SetName | (Inherited from SoBase.) |
| SetOverride | Turns the override flag on or off. |
| SetProjection | Set the current projection. |
| SetSynchronizable | Sets this to be a ScaleViz synchronizable object. |
| SetToDefaults | Sets all fields in this object to their default values. |
| ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) |
| Touch | Marks an instance as modified, simulating a change to it. |
| Write | (Inherited from SoNode.) |
Properties| Name | Description | |
|---|---|---|
 | centerPosition | Translation applied to the geometry. |
| floatParameters | Float parameters stored for projections. |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| isOn | If set to false, projection is inactive. |
| matrix | Matrix that can be applied before projecting a point. |
| parameters | String parameters stored for projections. |
| parametersIn | String parameters stored for projections. |
| projTypeId | Current projection id. |
| scaleFactor | Scale factor applied to the geometry. |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
RemarksThis property node is a specific OIV.Inventor.Nodes.SoProjection which applies a scale and recenter to a geometry.
The computation is done on the CPU before the transfer to OpenGL. The main purpose of this feature is to transform the vertex coordinates before sending them to OpenGL in order to avoid single precision issues, especially with the depth buffer.
Essentially this is a convenience node that automatically creates an OIV.Inventor.Projection.SbTransformProjection and calls the OIV.Inventor.Nodes.SoProjection.SetProjection(OIV.Inventor.Projection.SbProjection) method for you.
The result of a bounding box action is the coordinates of the bounding box after the projection because we need this version of the bounding box for rendering/clipping.
See OIV.Inventor.Nodes.SoProjection for important limitations of projection nodes.
