Detailed Description

The Material object represents a material property of a SceneItem object.

You can create a material with SceneItem::AddMaterial.

Note:: If you get a material from a Material Library, use ProjectItem::GetParent, not ProjectItem::GetModel, to get the Library object (ProjectItem::GetModel returns an invalid Model).

See also:: Scene::GetActiveMaterialLibrary(), OGLMaterial

Example:

        using namespace XSI;
        Application app;
        Model root = app.GetActiveSceneRoot();

        X3DObject myCube;
        root.AddGeometry( L"Cube",L"MeshSurface",L"" ,myCube );

        Material myMaterial;
        myCube.AddMaterial(L"Phong",false,L"",myMaterial);

        app.LogMessage( CString(L"The material: ") + myMaterial.GetFullName() );

Destroys a Material object.

Material ( const CRef & in_ref )

Constructs a Material object from a CRef object.

Member Function Documentation

bool IsA ( siClassID in_ClassID ) const [virtual]

Returns True if this object supports the functionality of a specified class. For example, a Material is a type of Property, so a Material object supports Property functionality.

Parameters:

in_ClassID Test if this object supports this class.

Returns:: True if this object supports the specified class, and false otherwise.

Reimplemented from Property.

siClassID GetClassID ( ) const [virtual]

Returns the class ID for this object.

Returns:: The class ID.

Reimplemented from Property.

Material& operator= ( const Material & in_obj )

Assigns a Material object to an existing Material object.

Parameters:

in_obj A Material object to be copied into this object.

Returns:: The reinitialized Material object.

Material& operator= ( const CRef & in_ref )

Assigns a CRef to this material. The Material object is cleared if the CRef is not a reference to an object that supports the Material class.

Parameters:

in_ref A reference to an object that supports the Material class.

Returns:: The reinitialized Material object.

Reimplemented from Property.

CRefArray GetShaders ( ) const

Returns the shaders connected to this material.

Returns:: An array of references to Shader objects.

CRefArray GetImageClips ( ) const

Returns the image clips connected to the material.

Returns:: An array of references to ImageClip objects.

Since:: 4.0

OGLMaterial GetOGLMaterial ( ) const

Returns the OGLMaterial for this material. The OGLMaterial is a read-only object that holds the material rendering information used by OpenGL.

OGLTexture GetOGLTexture ( ) const

Returns the OGLTexture for this Material. The OGLTexture is a read-only object that holds the texturing information used by OpenGL.

ClusterProperty GetCurrentUV ( ) const

Returns the ClusterProperty containing the current UV coordinages used to display the texture in OpenGL.

ImageClip GetCurrentImageClip ( ) const

Obsolete. Use Material::GetCurrentImageClip2 instead.

ImageClip2 GetCurrentImageClip2 ( ) const

Returns the current image clip used for OpenGL display.

Since:: 4.0

Texture GetCurrentTexture ( ) const

Returns the texture using the default UV coordinates used in OpenGL.

TextureLayer CreateTextureLayer	(	const CString &	in_strName = `CString()`,
		bool	in_bAfter = `true`,
		const TextureLayer &	in_refLayer = `TextureLayer()`
	)

Creates a new texture layer belonging to the container (the material).

Parameters:

in_strName	The name of new texture layer.
in_bAfter	True to insert the layer after the reference layer (in_refLayer), and False to insert the layer before the reference layer. If there is no reference layer, then True adds the layer to the end of the list, and False adds the layer to the start of the list.
in_refLayer	The reference texture layer. Used to indicate where the new layer is inserted in the list.

Returns:: The new texture layer.

Since:: 4.0

CStatus AddSharedTextureLayer	(	const TextureLayer &	in_layer,
		bool	in_bAfter = `true`,
		const TextureLayer &	in_refLayer = `TextureLayer()`
	)

Adds an existing texture layer to the container. The layer already belongs to at least one other texture layer container (either a Shader or a Material).

Parameters:

in_layer	The texture layer to add to this container.
in_bAfter	True to insert the layer after the reference layer (in_refLayer), and False to insert the layer before the reference layer. If there is no reference layer, then True adds the layer to the end of the list, and False adds the layer to the start of the list.
in_refLayer	The reference texture layer. Used to indicate where the new layer is inserted in the list.

Returns:: CStatus::OK if successful; CStatus::Fail if the texture layer could not be created.

Since:: 4.0

CRefArray GetTextureLayers ( ) const

Returns:: An array of references to TextureLayer objects.

Since:: 4.0

CStatus RemoveTextureLayer ( const TextureLayer & in_layer )

Removes a texture layer from the container. If this container is the only owner of the layer, then the layer is deleted from the scene. Otherwise, the layer is removed from this container only.

Parameters:

in_layer The texture layer to remove from this container.

Returns:: CStatus::OK if successful; CStatus::Fail if the texture layer could not be removed.

Since:: 4.0

CRefArray GetUsedBy ( ) const

Returns the owners of this material.

Returns:: An array of references to the owners.

Since:: 4.0

bool IsResolved ( )

Tests whether this material is the intended material or a stand-in.

Returns:: True if this material is the intended material, and False otherwise.

Since:: 4.0

CStatus Resolve ( )

Attempts to reconnect to the proper material. This works only when Material::IsResolved returns False.

Returns:: CStatus::OK if successful; CStatus::Fail if the material could not be resolved.

Since:: 4.0

CString GetUnresolvedFullname ( ) const

Returns the full name of the material that this material is supposed to reference.

Returns:: The fullname of the material.

Since:: 4.0

Library GetLibrary ( ) const

Property AddProperty	(	const CString &	in_preset,
		bool	in_bBranch = `false`,
		const CString &	in_name = `CString()`
	)

Adds a Property to the material. For example, you can add a UserDataBlob or CustomProperty to store custom user data inside a render tree.

Parameters:

in_preset	A preset name or the name of a self-installed CustomProperty.
in_bBranch	Should always be false.
in_name	Optional name for the new property. If no name is specified, the name is based on in_preset.

Returns:: The shader input type.; siUnknownParameterType if the parameter cannot be connected to a shader.

Since:: 5.0

CRefArray FindShaders ( const CString & in_filtername ) const
