static IPrecompPackedGeometry* Enlighten::IPrecompPackedGeometry::Create
public: IPrecompPackedGeometry * Create()
Create a new empty IPrecompPackedGeometry.
You can load data into an empty class with the IGeoSerialisable interface.
virtual Geo::GeoBoundingBox Enlighten::IPrecompPackedGeometry::GetBoundingBox
public: Geo::GeoBoundingBox GetBoundingBox() const
Get the axis aligned bounding box of the radiosity geometry.
virtual Geo::GeoGuid Enlighten::IPrecompPackedGeometry::GetId
public: Geo::GeoGuid GetId() const
Return the unique ID of this geometry.
virtual const IPrecompInputMesh* Enlighten::IPrecompPackedGeometry::GetInputMesh
public: const IPrecompInputMesh * GetInputMesh
(
  Geo::s32 idx
) const
Get the mesh at a given index.
Parameters
| [in] | idx | The index for the mesh, returned by the AddMesh call in IPrecompInputGeometry. Must be in the range 0 <= idx < GetNumMeshes(). |
Returns
A copy of the input mesh (after required internal preprocessing such as autoUVs or face winding changes), or NULL if the index is out of range.
virtual const IPrecompPackedGeometry* Enlighten::IPrecompPackedGeometry::GetLod
public: const IPrecompPackedGeometry * GetLod
(
  Geo::s32 lodIndex
) const
Get a given (lodIndex) Lod of this geometry.
GetLod(0) will return the geometry itself. If lodIndex if greater or equal than value returned by GetNumLods(), then the last (lowest quality) Lod is returned.
virtual const PrecompMeshProperties* Enlighten::IPrecompPackedGeometry::GetMeshProperties
public: const PrecompMeshProperties * GetMeshProperties
(
  Geo::s32 idx
) const
Get the mesh properties for a given index.
Parameters
| [in] | idx | The index for the mesh, returned by the AddMesh call in IPrecompInputGeometry. Must be in the range 0 <= idx < GetNumMeshes(). |
Returns
The mesh properties provided by the user in the input geometry class, or NULL if the index is out of range.
virtual const char* Enlighten::IPrecompPackedGeometry::GetName
public: const char * GetName() const
Get the full name.
virtual Geo::s32 Enlighten::IPrecompPackedGeometry::GetNumLods
public: Geo::s32 GetNumLods() const
Get number of Lods of this geometry.
virtual Geo::s32 Enlighten::IPrecompPackedGeometry::GetNumMeshes
public: Geo::s32 GetNumMeshes() const
Returns the number of meshes in the output geometry.
virtual Geo::s32 Enlighten::IPrecompPackedGeometry::GetNumVerts
public: Geo::s32 GetNumVerts
(
  Geo::s32 idx
) const
Returns the number of vertices in the output geometry for the given mesh index.
Note
This will return -1 if the mesh did not have uvs generated for it.

virtual const Geo::s32* Enlighten::IPrecompPackedGeometry::GetOutputChartIdsArray
public: const Geo::s32 * GetOutputChartIdsArray
(
  Geo::s32 id
) const
Returns a pointer to a per-vertex chart id information for the given mesh id.
virtual const Geo::GeoPoint2* Enlighten::IPrecompPackedGeometry::GetOutputUvArray
public: const Geo::GeoPoint2 * GetOutputUvArray
(
  Geo::s32 id
) const
Returns a pointer to the per-vertex uvs for the given mesh index.
Note
This will return NULL if the mesh did not have uvs generated for it.

virtual Geo::GeoPair<Geo::s32, Geo::s32> Enlighten::IPrecompPackedGeometry::GetOutputUvSize
public: Geo::GeoPair< Geo::s32, Geo::s32 > GetOutputUvSize() const
Returns the size of the UV texture for which the UV coordinates were calculated.
virtual float Enlighten::IPrecompPackedGeometry::GetProjectionCost
public: float GetProjectionCost() const
Get the projection cost for the geometry.
Lower is better.
Note
This measure is not comparable between meshes. Only compare it with different projections of the same mesh.
virtual float Enlighten::IPrecompPackedGeometry::GetProjectionCost
public: float GetProjectionCost
(
  Geo::s32 meshIdx
) const
Get the projection cost for an individual mesh.
Lower is better.
Note
This measure is not comparable between meshes. Only compare it with different projections of the same mesh.
virtual float Enlighten::IPrecompPackedGeometry::GetSurfaceArea
public: float GetSurfaceArea() const
Get the estimated surface area of the radiosity geometry.
virtual float Enlighten::IPrecompPackedGeometry::GetTargetUsagePercentage
public: float GetTargetUsagePercentage() const
Get the percentage of the output UV texture occupied.
virtual float Enlighten::IPrecompPackedGeometry::GetUVArea
public: float GetUVArea() const
Get the estimated UV surface area of the radiosity geometry.
virtual bool Geo::IGeoSerialisable::Load
public: bool Load
(
  IGeoInputStream & stream,
  Geo::u32 section
)
Load an instance of this class from an IGeoInputStream.
The stream must be ready to read from. You can load sections of an object by passing a bitmask representing the desired sections rather than Iff::AllSectionsMask, which will load all sections. It is also safe to call this method on an object multiple times with different section arguments to load multiple parts.
virtual void Geo::IGeoReleasable::Release
public: void Release()
Free this object that was created within the Enlighten libraries.
Expect this to behave in a similar way to calling 'delete(this)'
virtual bool Geo::IGeoSerialisable::Save
public: bool Save
(
  IGeoStream & stream,
  Geo::u32 section
) const
Save an instance of this class to an IGeoStream.
The stream must be ready to write to. You can save sections of an object by passing a bitmask representing the desired sections rather than Iff::AllSectionsMask, which will save all sections that are available.
