Functions

virtual Geo::s32 Enlighten::IPrecompInputGeometry::AddMesh

---

public: Geo::s32 AddMesh
(
    IPrecompInputMesh * mesh,
    const PrecompMeshProperties * properties
)

---

Adds a Mesh to the geometry.

Returns

Returns the internal array index the mesh as added as (-1 means fail). To save unnecessary copies this call takes ownership of the mesh pointer. This object will be responsible for freeing the resource when it's not longer in use - do not hang onto this pointer. (Note the lack of a const qualifier). It does take a copy of the properties data though. It is the clients responsibility to manage this resource. The caller should make a note of the returned index. You should use this index to lookup the generated uvs in the compiled packed geometry object, if required by the mesh properties.

virtual Geo::s32 Enlighten::IPrecompInputGeometry::AddMesh

---

public: Geo::s32 AddMesh
(
    const Geo::GeoRefReleasePtr< IPrecompInputMesh > & mesh,
    const PrecompMeshProperties * properties
)

---

Adds a Mesh to the geometry.

Returns

Returns the internal array index the mesh as added as (-1 means fail). To save unnecessary copies this call takes a reference-counted pointer to the mesh. Any other references to the mesh must also go through a Geo::GeoRefReleasePtr. It does take a copy of the properties data though. It is the clients responsibility to manage this resource. The caller should make a note of the returned index. You should use this index to lookup the generated uvs in the compiled packed geometry object, if required by the mesh properties.

Returns true is this Geometry is a terrain 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.

virtual void Enlighten::IPrecompInputGeometry::SetClampUvs

---

public: void SetClampUvs
(
    bool b
)

---

Set whether projected vertices should be clamped within the target chart when possible.

See the technical user manual for more details on this control. Defaults to true.

virtual void Enlighten::IPrecompInputGeometry::SetHighQualityProjection

---

public: void SetHighQualityProjection
(
    bool b
)

---

Set whether the projection should be done using uniform sampling of the mesh surface instead of only using the mesh vertices.

For meshes with triangles significantly larger than the output pixel size this may result in better results especially in cases of small overhangs in the detail mesh. Defaults to false.

virtual void Enlighten::IPrecompInputGeometry::SetId

---

public: void SetId
(
    Geo::GeoGuid id
)

---

Sets the globally unique ID of this geometry.

virtual void Enlighten::IPrecompInputGeometry::SetIsTerrain

---

public: void SetIsTerrain
(
    bool isTerrain
)

---

Set whether this geometry is part of the terrain.

Terrain is treated specially by the precompute pipeline. If given Geometry is set to be terrain geometry, then it also needs to have, terrainU and terrainV directions set.

virtual void Enlighten::IPrecompInputGeometry::SetMeshSimplificationAutoOrientation

---

public: void SetMeshSimplificationAutoOrientation
(
    bool enabled
)

---

Enable/disable packer rotation.

Set this to enable or disable UV chart rotations while packing. In mesh simplification, the packing can attempt to orient UV charts to the horizontal axis which improves the packing quality. However, in cases where UVs have been sensibly authored previous to this step, this may be undesirable. The default is false.

virtual void Enlighten::IPrecompInputGeometry::SetMinChartSizeInBlocks

---

public: void SetMinChartSizeInBlocks
(
    Geo::s32 size
)

---

Set the minimum chart size in precompute blocks.

virtual void Enlighten::IPrecompInputGeometry::SetName

---

public: void SetName
(
    const char * name
)

---

Sets the globally unique name of this geometry.

virtual void Enlighten::IPrecompInputGeometry::SetNumLods

---

public: void SetNumLods
(
    Geo::s32 numLods
)

---

Set number of Lods packing should generate for this input geometry.

virtual void Enlighten::IPrecompInputGeometry::SetOutputPixelSize

---

public: void SetOutputPixelSize
(
    float size
)

---

Set the output lightmap resolution.

This gives the atlas packing stage a guide to how many pixels it should assign to this geometry. It defines the length of one edge of a radiosity pixel given in world units (as defined by the geometry).

virtual void Enlighten::IPrecompInputGeometry::SetOutputPixelSize

---

public: void SetOutputPixelSize
(
    float size,
    Geo::s32 fixedAtlasWidth,
    Geo::s32 fixedAtlasHeight
)

---

Set the output lightmap resolution.

Defines the length of one edge of a radiosity pixel given in world units (as defined by the geometry) and also explicitly set how many pixels should be assigned.

Parameters

virtual void Enlighten::IPrecompInputGeometry::SetPrecompBlockSize

---

public: void SetPrecompBlockSize
(
    Geo::s32 size
)

---

Set the precompute block size.

This defines the granularity of the packing algorithm and also the minimum resulting chart size in pixels. The precompute block size needs to be 2 or a multiple of 4. NOTE: All geometries of one system need to use the same value.

virtual void Enlighten::IPrecompInputGeometry::SetTerrainU

---

public: void SetTerrainU
(
    Geo::v128 const & terrainU
)

---

Set the U projection direction for terrain geometry.

virtual void Enlighten::IPrecompInputGeometry::SetTerrainV

---

public: void SetTerrainV
(
    Geo::v128 const & terrainV
)

---

Set the V projection direction for terrain geometry.

virtual void Enlighten::IPrecompInputGeometry::SetUvSimpMaxNumSimplifications

---

public: void SetUvSimpMaxNumSimplifications
(
    Geo::s32 maxSimplificiations
)

---

UV Simplification: set a maximum number of simplification to make.

Once this number of simplifications have been found the process will stop trying to find others and continue with the rest of the uv generation and projection as normal. The algorithm will tend to find the most significant simplifications first, so this can be used to limit the amount of time and effort put into less interesting simplifications. Must be at least 1. The default is 100.

virtual void Enlighten::IPrecompInputGeometry::SetUvSimpNumIterationsPerSimplification

---

public: void SetUvSimpNumIterationsPerSimplification
(
    Geo::s32 numIterations
)

---

UV Simplification: set the number of iterations to allow per simplification.

Greater iteration counts tend to find better simplifications, but take longer. Must be at least 1. The default is 300.
