    This is the documentation for Enlighten.

    class Enlighten RadIrradianceTask

    Sept 09, 2025

    class Enlighten::RadIrradianceTask

    Structure describing a task using the irradiance technique.

    Variables

    Name Description
    const RadSystemCore * m_CoreSystem

    Precompute data for system solved in this task.

    void * m_DirectionalOutput

    Optional luminance or red directional output.

    void * m_DirectionalOutputB

    Optional blue directional output.

    void * m_DirectionalOutputG

    Optional green directional output.

    Geo::s32 m_DirectionalOutputStride

    The stride of the directional output texture in pixels (if present).

    const InputLightingBuffer * m_Environment

    Emissive environment for the task to read from. Must be 16-byte aligned, although may be NULL.

    const InputLightingBuffer ** m_InputLighting

    Ordered list of input lighting buffers that the task can read from.

    void * m_IrradianceOutput

    Radiosity output. The data must be persistent if temporal coherence is used.

    bool m_LegacyDirectionalOutput

    If true (the default), the re-balancing coefficient used in the legacy surface re-lighting model is output to the alpha channel of the directional output texture(s).

    Geo::s32 m_NumSystemToSystemTransfers

    Number of system-to-system transfers in the list.

    eOutputFormat m_OutputFormat

    Output format: one of the OUTPUT_FORMAT_* constants.

    eOutputFormatByteOrder m_OutputFormatByteOrder

    Whether to output 8-bit-per-pixel data in BGRA (DX9) or RGBA (DX11) byte order.

    float m_OutputScale

    Constant to premultiply by before format conversion.

    Geo::s32 m_OutputStride

    The stride of the output texture in pixels.

    void * m_PersistentData

    Persistent data used for storing data which persists between solves.

    const RadSystemToSystemTransfer * m_SystemToSystemTransfers

    List of system-to-system transfers to add into the irradiance task.

    float m_TemporalCoherenceEpsilon

    Small bias value added to the lighting intensity to ensure stable computation.

    float m_TemporalCoherenceThreshold

    The threshold value for temporal coherence.

    Functions

    Name Description
    RadIrradianceTask()

    Default constructor.


    Enlighten::RadIrradianceTask::RadIrradianceTask

    public: RadIrradianceTask()

    Default constructor.
