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.
