(

...

Converts the endian format of a runtime object.

All data generated by the precompute is in little endian format and before use on big endian machines (i.e. consoles) it must be converted to the native endian format using these functions. This conversion may be done on load, or by some user-defined content generation step. Note that the loader functions in EnlightenUtils assume the data files to be in little endian format, and call these functions at load time to flip them to the native format.

...

Create a Direction Palette for use with an EntireProbeSetTask.

The returned DirectionPalette can be used with any probeset with matching SH order, axis permutation and coefficient output order. The RadProbeSetMetaData class contains the shOrder, basis and coefficient output order for any given probeset.

Parameters

[in]	BasisX	The first of the basis directions. Must be a unit vector along either the X, Y, or Z axis.
[in]	BasisY	The second of the basis directions. Must be a unit vector along either the X, Y, or Z axis.
[in]	BasisZ	The third of the basis directions. Must be a unit vector along either the X, Y, or Z axis.
[in]	coefficientOutputOrder	The output order of the SH coefficients. Must be 9 elements long.
[in]	mem	A non-null pointer to a 16-byte aligned block of memory of size calculated with CalcDirectionPaletteSize.

Returns

Pointer to created DirectionPalette, NULL if error.

public: bool GEO_CALL FreezeEntireProbeSetTask
(
const Enlighten::EntireProbeSetTask * task,
void * workspace,
Geo::u32 & timeUs,
Geo::u32 & numSolvedProbes
)

...

The temporal coherence optimization - if used - requires that all probe sets are kept in sync, so that no changes in lighting are missed.

Nevertheless, some probe sets can be updated less frequently than others by using the Freeze functions in place of a solve. FreezeEntireProbeSetTask performs the minimal housekeeping required to keep track of light changes for the temporal optimization - no output SH coefficients are updated. The input parameters are exactly the same as for SolveEntireProbeSetTask.

Parameters

[in]	task	A valid pointer to the probe task structure to freeze.
[in]	workspace	A valid pointer to a block of memory to use as a workspace which must be at least as big as m_RequiredWorkspaceSize in the core meta data.
[out]	timeUs	Number of microseconds it took to freeze the task.
[out]	numSolvedProbes	Number of probes solved in the task. This will always be 0.

bool GEO_CALL Enlighten::FreezeInputLightingBuffer

...

public: bool GEO_CALL FreezeInputLightingBuffer
(

...

The temporal coherence optimisation - if used - requires that all systems are kept in sync, so that no changes in lighting are missed.

Nevertheless, some systems can be updated less frequently than others by using the Freeze functions in place of a solve. FreezeInputLightingBuffer marks an input lighting buffer as frozen. Other systems reading this buffer then recognise that the input hasn't changed. (Neglecting to freeze buffers won't cause visual artefacts, but will result in performing more recalculations than necessary.)

Parameters

[in]

lightingBuffer

The input lighting buffer to mark as frozen.

Retrieves the light probe environment visibility for the given probe in the volume probe data.

The visibility data is encoded as a spherical harmonic with a number of coefficients depending on the precompute settings used to create the probe set. The number of coefficients can be retrieved from the probeSetCore metadata. The visibility pointer must point to a buffer that is large enough to accommodate the coefficients. Returns a pointer to the visibility data, this pointer will be NULL if the environment visibility is disabled or the probe has been culled by the precompute.

Set whether to force disable FMA4 support.

This only affects the SSE solver, and has no effect on other architectures. By default, if FMA4 support is detected in the hardware and OS it will be used by the solver. This function allows you to override the automatic detection and force FMA4 support off. There is no way to force it on if Enlighten cannot detect it.
