Detailed Description

Defines an occurrence of assembly or part in a scene graph.

Instance contains a reference to another element part or assembly and is used to share data, e.g. two instances can share the same part adding own transformations. Instance points to a specific scene graph element configuration and may return base configuration of reference scene graph element.

Constructor & Destructor Documentation

Instance() [1/3]

cadex::ModelData::Instance::Instance ( const UTF16String & theName )

explicit

Constructor.

Creates an instance with the specified name.

Instance() [2/3]

cadex::ModelData::Instance::Instance ( const ModelElement & theElement, const UTF16String & theName = UTF16String() )

explicit

Constructor.

Creates an instance referencing /a theElement with the provided name. If /a theElement is null (IsNull()), no reference is set.

Instance() [3/3]

cadex::ModelData::Instance::Instance	(	const ModelElement &	theElement,
		const Geom::Transformation &	theTransformation,
		const UTF16String &	theName = UTF16String() )

Constructor.

Creates an instance referencing /a theElement with the provided name and transformation. If /a theElement is null (IsNull()), no reference is set.

Member Function Documentation

HasTransformation()

bool cadex::ModelData::Instance::HasTransformation

(

)

const

Returns true if the instance has an explicitly attached transformation matrix.

Returns true if the matrix has been assigned with SetTransformation() and false otherwise.

See also

SetTransformation(), Transformation().

Reference()

ModelElement cadex::ModelData::Instance::Reference

(

)

const

Returns the referenced object.

Returns null if the instance does not refer to any object.

See also

SetReference().

Transformation()

const Geom::Transformation & cadex::ModelData::Instance::Transformation

(

)

const

Returns the transformation matrix.

If the matrix has not been explicitly assigned with SetTransformation() then creates and explicitly assigns an identity matrix.
