SyntaxThe SoModelMatrixElement type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | CallSetElt | Obsolete. Calls CallSetElt(matrix, true). |
| Equals | (Inherited from Object.) |
 | Get(SoState) | Returns current model matrix from the state. |
| Get(SoState, Boolean) | Returns current model matrix from the state, sets given flag to true if matrix is known to be identity. |
| GetClassStackIndex | Obsolete. Returns the stack id for this element. |
| GetCombinedCullMatrix | This method gets the model*cullMatrix combined matrix (which is cached by this element). |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MakeIdentity | Sets the model matrix to the identity matrix. |
| Mult | Multiplies the given matrix into the model matrix. |
| Pop | Pops element. |
| PopMatrix | This method is used by the TransformSeparator node. |
| Push | Overrides push() method to copy values from next instance in the stack. |
| PushMatrix | This method is used by the TransformSeparator node. |
| RotateBy | This multiplies a matrix that performs the specified transformation into the model matrix. |
| ScaleBy | This multiplies a matrix that performs the specified transformation into the model matrix. |
| Set(SoState, SoNode, SbMatrix) | Calls Set(state, node, matrix, true). |
| Set(SoState, SoNode, SbMatrix, Boolean) | Sets the model matrix to the given matrix. |
| SetCullMatrix | Sets the transformation that defines the volume that view-volume culling should be tested against. |
| SetElt | Obsolete. Calls SetElt(matrix, true). |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| TranslateBy | This multiplies a matrix that performs the specified transformation into the model matrix. |
RemarksThis element stores the current model matrix - the cumulative transformation applied to subsequent shapes. Because the matrix is cumulative, this class is derived from SoAccumulatedElement. The set() method replaces the current matrix, while all the others (mult(), translateBy(), etc.) multiply into it. Node id's of the nodes that affect the element are accumulated properly.
This element also stores the current view-volume culling transformation, which is normally the view*projection matrices (set by cameras), but which may be modified by sophisticated culling schemes.
