Detailed Description

A COLLADA geometry entity.

There are three types of COLLADA geometry entities: meshes, NURBS surfaces and splines. NURBS Surfaces are part of the Premium Build only.*

Meshes are collections of polygons where the vertices always have a position, usually have a normal to define smooth or hard edges and may be colored or textured.

Parameterized surfaces (PSurface) are a list of parameterized patches defined as a sequence of weighted control points that may be associated with two knot vectors and possibly trimming curves to define a 3D surface.

Note: "PSurfaces" are part of the Premium Build only.

Splines are a sequence of control points used to generate a smooth curve.

Constructor & Destructor Documentation

FCDGeometry::FCDGeometry (  FCDocument *  document  )

Contructor: do not use directly. Create new geometries using the FCDLibrary::AddEntity function. Parameters: document  The COLLADA document which owns the new geometry entity.

---

Member Function Documentation

virtual FCDEntity* FCDGeometry::Clone (  FCDEntity *  clone = NULL, bool  cloneChildren = false )  const [virtual]

Copies the geometry entity into a clone. The clone may reside in another document. Parameters: clone  The empty clone. If this pointer is NULL, a new geometry entity will be created and you will need to release the returned pointer manually. cloneChildren  Whether to recursively clone this entity's children. Returns: The clone. Reimplemented from FCDEntity.

FCDGeometryMesh* FCDGeometry::CreateMesh (   )

Sets the type of this geometry to mesh and creates an empty mesh structure. This function will release any mesh or spline structure that the geometry may already contain Returns: The mesh information structure. This pointer will always be valid.

FCDGeometrySpline* FCDGeometry::CreateSpline (   )

Sets the type of this geometry to spline and creates an empty spline structure. This function will release any mesh or spline structure that the geometry may already contain. Returns: The spline information structure. This pointer will always be valid.

FCDGeometryMesh* FCDGeometry::GetMesh (   )  [inline]

Retrieves the mesh information structure for this geometry. Verify that this geometry is a mesh using the IsMesh function prior to calling this function. Returns: The mesh information structure. This pointer will be NULL when the geometry is a spline or is undefined.

FCDGeometrySpline* FCDGeometry::GetSpline (   )  [inline]

Retrieves the spline information structure for this geometry. Verify that this geometry is a spline using the IsSpline function prior to calling this function. Returns: The spline information structure. This pointer will be NULL when the geometry is a mesh or is undefined.

virtual Type FCDGeometry::GetType (   )  const [inline, virtual]

Retrieves the entity class type. This function is a part of the FCDEntity interface. Returns: The entity class type: GEOMETRY. Reimplemented from FCDEntity.

bool FCDGeometry::IsMesh (   )  const [inline]

Retrieves whether the type of this geometry is a mesh. Returns: Whether this geometry is a mesh.

bool FCDGeometry::IsPSurface (   )  const [inline]

Retrieves whether the type of this geometry is a parameterized surface. Returns: Whether this geometry is a parameterized surface.

bool FCDGeometry::IsSpline (   )  const [inline]

Retrieves whether the type of this geometry is a spline. Returns: Whether this geometry is a spline.

void FCDGeometry::SetMesh (  FCDGeometryMesh *  data  )  [inline]

[INTERNAL] Set geometry information. Parameters: data  The specific geometry data structure.
