const IPrecompInputSystem * pSystem,
const IPrecompInputGeometry *const * ppInputGeometry,
Geo::s32 numGeometries,
Geo::IGeoProgressProxy * progress,
IPrecompPackedSystem *& oSystem
)

Assemble system geometry.

If a system is going to be used as probe radiosity, then the input processing is greatly reduced (there is no need to pack the geometry and create the UV chart mappings).

Parameters

[in]	pSystem	The system to pack
[in]	ppInputGeometry	The geometry referred to (by Id) in this system's PrecompInputInstances. You may pass more geometry items than are necessary, but all Id's used in the instances must have a packed geometry available.
[in]	numGeometries	The number of packed geometry classes in the above array
[in]	progress	This object is updated during this function call to give feedback on progress
[out]	oSystem	The final packed system

virtual Geo::s32 Enlighten::IPrecompute::CalculateCubeMapSystemDependencies

public: Geo::s32 CalculateCubeMapSystemDependencies
(
const IPrecompInputCubeMap * pCubeMap,
const IPrecompPackedSystem *const * ppSystems,
Geo::s32 numSystems,
Geo::IGeoProgressProxy * progress,
IPrecompSystemDependencies *& oDependencies
)

Calculate system dependencies for a cube map.

Each IPrecompInputCubeMap may have dependencies calculated by calling this function on it. All packed systems which are fully loaded will have their geometry fully represented in the visibility tests. Packed systems which only have a header (ie whose geometry isn't loaded) will be represented by their bounding boxes in the visibility tests. (In the HLBS these sets of systems are controlled by the "expansionDistance" parameter.)

Parameters

[in]	pCubeMap	The cube map for which to calculate dependencies
[in]	ppSystems	The list of systems to include in this calculation.
[in]	numSystems	The number of packed systems in the above array
[in]	progress	This object is updated during this function call to give feedback on progress
[out]	oDependencies	The approximate set of system dependencies, which may be fed back into the precompute.

const IPrecompInputProbeSet * pProbeInput,
const IPrecompPackedSystem *const * ppSystems,
Geo::s32 numSystems,
Geo::IGeoProgressProxy * progress,
IPrecompSystemDependencies *& oDependencies
)

Calculate system dependencies for a probe set.

Each IPrecompInputProbeSet may have dependencies calculated by calling this function on it. The collection of systems passed in determines the connectivity between them, so completely isolated systems have a numSystems of 1. All packed systems which are fully loaded will have their geometry fully represented in the visibility tests. Packed systems which only have a header (ie whose geometry isn't loaded) will be represented by their bounding boxes in the visibility tests. (In the HLBS these sets of systems are controlled by the "expansionDistance" parameter.)

Parameters

[in]	pProbeInput	The probe set for which to calculate dependencies
[in]	ppSystems	The list of systems to include in this calculation.
[in]	numSystems	The number of packed systems in the above array

)

Calculate system dependencies for a system.

Each IPrecompInputSystem may have dependencies calculated by calling this function on it.

const IPrecompSystemPreClustering *const * ppPreClusterings,
Geo::IGeoProgressProxy * progress,
IPrecompOutputCubeMap *& oCubeMapOutput
)

Run the precompute for a cube map.

This function takes a description of a cube map as a IPrecompInputCubeMap and runs the precompute to produce an IPrecompOutputCubeMap. The runtime data can then be extracted from this object.

Removing systems that the cube map cannot see will make this stage faster.

[in]	numClusterings	The number of clusterings in the above array

Geo::s32 numClusterings,
Geo::IGeoProgressProxy * progress,
IPrecompSystemLightTransport *& oLightTransport
)

Create the light transport for a system.

Each light-mapped system must have a light transport created by calling this function on it. The clustering object for each system to be considered as input (the dependencies), whether light-mapped or not, should be passed in. These are used to determine the bounced light that a given pixel in the system of interest can see. The packed system object of each light-mapped system to be considered as input should be passed in separately. These are used to determine connectivity in light-map space, and ensure boundaries between systems are as smooth as possible.

Note

There are two versions of this function. This simpler version assumes you do not want any projected point data generated. It is equivalent to calling the second function as: CreateSystemDusters(pClustering, ppClusterings, numClusterings, NULL, 0, NULL, 0, NULL, progress, oDuster);

virtual Geo::s32 Enlighten::IPrecompute::CreateSystemDusters

public: Geo::s32 CreateSystemDusters
(
const IPrecompSystemClustering * pClustering,
const IPrecompSystemClustering *const * ppClusterings,
Geo::s32 numClusterings,
const PointProjectionSurface * surfaceArray,
Geo::s32 numSurfaces,
const PointProjectionVersion * versionArray,
Geo::s32 numVersions,
const PointProjectionOptions * projectionOptions,
Geo::IGeoProgressProxy * progress,
IPrecompSystemDuster *& oDuster
)

Create the platform-agnostic runtime input sample points including versions of projected points.

This function will optionally generate alternative versions of the input sample points (duster points). If created, these will be exported via the m_ProjectedPointData RadDataBlock of the InputWorkspace runtime object when this class is compiled to a specific platform. If you do not want point projection data, you can simply pass NULLs as appropriate. There is a second version of this function which does this for you. In particular, if no versions are specified (numVersions == 0), the call will succeed and will not generate any additional data.

The m_ProjectedPointData RadDataBlock in the InputWorkspace is a collection of per-instance sets of input sample points that have been projected to the meshes provided to this call. The m_ProjectedPointData RadDataBlock is optional and will only be loaded at runtime if you provide the Enlighten::Iff::ProjectedPointsInputWorkspaceDataSection to Enlighten::ReadInputWorkspaceFromFile().

Point projection works well when projecting onto an alternative representation of the same geometry, such as a different LOD level. The geometry to project onto is provided as a set of 'surfaces', each of which consist of an IPrecompInputMesh, a transformation matrix and boolean. This is the PointProjectionSurface class. Note that only the positions and normals of the meshes are used in the projection. The set of surfaces to use is specified per-instance, per-version, with the PointProjectionVersion class.

"Versions" can be thought of as a generalisation of LODs. They are just an alternative representation for an instance, and although version IDs need to be unique per-instance, they can be any value. In particular, they do not need to start at 0, or be contiguous, or positive (e.g. -100,-1,4,5 are all fine). This function will fail and report an error if you specify the same version ID for an instance more than once. It will also fail if the m_TargetSurfaces array is 0 length, or contains invalid indices or refers to null pointers and so on, but we will accept geometry that is empty (no triangles or vertices). In this case, it is not possible to project the points so we keep their original locations and create a version entry with this data. This is redundant (the points are the same), but it allows us to handle this scenario correctly and without creating an edge case in the runtime. In particular, all versions of the points for an instance will have the same number of points in all cases.

Instances that are known by the precompute (and therefore the InputWorkspace), but do not have projected point versions explicitly created for them have zero points in the resulting RadDataBlock. See the runtime API for further details.

The projection code will find the closest position on the specified geometry for each duster point. But it can also attempt to find a better position in front of itself, along its normal, if this helps it sit on top of nearby obscuring geometry. This can help prevent points being hidden under small details. This behaviour is optional and disabled if maxRayIntersectionDistance in the PointProjectionOptions class is 0 or negative. (Default is 0.)

The ppClusterings array of dependent clusterings is used to correctly determine transparency offsets per cluster, it has to contain the pClustering system.

Note that terrain instances will always be automatically grouped into a different system than non-terrain instances.
