virtual bool Enlighten::IPrecompInputProbeSet::IsOctree

public: bool IsOctree() const

Returns true if this probe set was generated for a probe octree.

virtual bool Enlighten::IPrecompInputProbeSet::IsRegularGrid

public: bool IsRegularGrid() const

Returns if this probe set is a probe grid.

This is only true if the probe positions form a single fully occupied regular grid and there are no duplicates or probe positions outside of the grid.

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::IPrecompInputProbeSet::SetId

public: void SetId
(
Geo::GeoGuid id
)

Set the unique ID of this light probe set.

virtual void Enlighten::IPrecompInputProbeSet::SetName

public: void SetName
(
const char * name
)

Set a globally unique name.

virtual bool Enlighten::IPrecompInputProbeSet::SetProbePositions

public: bool SetProbePositions
(
const Geo::v128 & origin,
const Geo::v128 & basisX,
const Geo::v128 & basisY,
const Geo::v128 & basisZ,
const Geo::v128 * begin,
const Geo::v128 * end
)

Copy light probe position values between [begin, end) into this object.

Previous positions are deleted. The bounding box is defined by a set of orthogonal basis vectors and their origin. The basis vectors are required to be orthogonal. The lengths of the basis vectors define the size of the bounding box.

Parameters

[in]	origin	Origin of the basis vectors.
[in]	basisX	First basis vector.
[in]	basisY	Second basis vector.
[in]	basisZ	third basis vector.
[in]	begin	A pointer to the first element to be added
[in]	end	A pointer to an element one past the last entity (as standard STL syntax)

Returns

True if the operation succeeded, false if there was not enough memory to satisfy the request or if the bounding box either has zero volume or its basis vectors are not orthogonal.

virtual bool Enlighten::IPrecompInputProbeSet::SetRandomProbePositions

public: bool SetRandomProbePositions
(
const Geo::v128 & origin,
const Geo::v128 & basisX,
const Geo::v128 & basisY,
const Geo::v128 & basisZ,
const Geo::s32 numProbes,
const Geo::s32 & seed
)

Create an random set of light probes within a non axis aligned bounding box.

Previous positions are deleted. The bounding box is defined by a set of orthogonal basis vectors and their origin. The basis vectors are required to be orthogonal. The lengths of the basis vectors define the size of the bounding box. A defined number of probes in the range [1..65536] are placed randomly within the bounding box.

Parameters

[in]	origin	Origin of the basis vectors.
[in]	basisX	First basis vector.
[in]	basisY	Second basis vector.
[in]	basisZ	Third basis vector.
[in]	numProbes	Number of probes placed in the bounding box.
[in]	seed	A seed value to ensure consistency between invocations.

Returns

True if the operation succeeded, false if there was not enough memory to satisfy the request or if the bounding box either has zero volume or its basis vectors are not orthogonal.

virtual bool Enlighten::IPrecompInputProbeSet::SetRegularGridProbePositions

public: bool SetRegularGridProbePositions
(
const Geo::v128 & origin,
const Geo::v128 & basisX,
const Geo::v128 & basisY,
const Geo::v128 & basisZ,
const Geo::s32 resolutionX,
const Geo::s32 resolutionY,
const Geo::s32 resolutionZ
)

Create light probes based on a regular grid.

Previous positions are deleted. The regular grid is defined by a set of orthogonal basis vectors and their origin as well as the resolution in each basis vector direction. The basis vectors are required to be orthogonal and the resolution must be in the range [1..65536] otherwise this function will return false. The lengths of the basis vectors define the size of the regular grid. Based on the resolutions, the regular grid is split up into cells, and at the center of each cell a probe gets placed. This means that a regular grid with a resolution of 1 in each basis vector direction will have its single probe placed in the center of the grid and not

at the basis vector origin.

Parameters

[in]	origin	Origin of the basis vectors.
[in]	basisX	First basis vector.
[in]	basisY	Second basis vector.
[in]	basisZ	third basis vector.
[in]	resolutionX	Number of probes in the direction of the first basis vector.
[in]	resolutionY	Number of probes in the direction of the second basis vector.
[in]	resolutionZ	Number of probes in the direction of the third basis vector.

Returns

True if the operation succeeded, false if there was not enough memory to satisfy the request or if the bounding box either has zero volume or its basis vectors are not orthogonal.
