Public Fields​

LightEstimationCreated​


public bool LightEstimationCreated { get; set; }

Public Methods​

bool CheckEstimationEstimateReadiness​

Determines if enough time has passed for a light estimation estimate to obtain data. 

public bool CheckEstimationEstimateReadiness()

Returns: The readiness of the light estimation estimate.

void CreateLightEstimation​

Creates a light estimation to enable light estimates to be created for a given cubemap resolution. 

public void CreateLightEstimation(
    HDRCubemapFaceResolution cubemapFaceResolution
)

Parameters

TypeNameDescription
HDRCubemapFaceResolutioncubemapFaceResolutionThe width/height resolution of the face of the cubemap to be used.

void DestroyLightEstimation​

Destroys the active light estimation so light estimates can no longer be created. 

public void DestroyLightEstimation()

Cubemap GetEstimateCubemap​

Gets a Unity Cubemap object from a light estimate's cubemap data. 

public Cubemap GetEstimateCubemap(
    float [] rawPixelsArray,
    int faceDim
)

Parameters

TypeNameDescription
float []rawPixelsArrayThe float array of pixels obtained from a light estimation estimate.
intfaceDimThe desired width/height dimension of each face of the cubemap.

Returns: A cubemap object from the light estimate data in a format usable by Unity.

long GetLastUpdateTime​

Gets the last time that the light estimation state was updated. 

public long GetLastUpdateTime()

Returns: The time of last update in nanoseconds.

EstimateData GetLightEstimationEstimateData​

Creates a light estimation estimate, obtains the light estimate data, then destroys the light estimate. 

public EstimateData GetLightEstimationEstimateData()

Returns: The data obtained from a light estimation estimate.
