How to implement Environmental HDR Lighting Estimation in Sceneform?

Question

I´m trying to implement lighting estimation with new Google's API Environmental HDR. I'm following the instructions in developer guide, but I don't know how to implement the app-specific code.

I have configure the session like this:

config.setLightEstimationMode(Config.LightEstimationMode.ENVIRONMENTAL_HDR);
session.configure(config);

And put this code in my update call

private void onSceneUpdate(FrameTime frameTime) {

    if (fragment instanceof ArFragment && loadedRenderable) {

        if ( frame == null )
            return;
            LightEstimate lightEstimate = frame.getLightEstimate();
            // note - currently only out param.
            float[] intensity = lightEstimate.getEnvironmentalHdrMainLightIntensity(); 
            float[] direction = lightEstimate.getEnvironmentalHdrMainLightDirection();
            //app.setDirectionalLightValues(intensity, direction);

            float[] harmonics = lightEstimate.getEnvironmentalHdrAmbientSphericalHarmonics();
            //app.setAmbientSphericalHarmonicsLightValues(harmonics); // app-specific code.

            // Get HDR environmental lighting as a cubemap in linear color space.
            Image[] lightmaps = lightEstimate.acquireEnvironmentalHdrCubeMap();

            for (int i = 0; i < lightmaps.length /*should be 6*/; ++i) {
                //app.UploadToTexture(i, lightmaps[i]);

            }
        }
    }
}

I can't figure out what to do with the parameters provided by those methods

I just want to light the 3D model with the same light conditions as the scene. Can anyone help me to achieve this? Or provide any example?

did you get any solution? – Auraaural

i have black models when apply ENVIRONMENTAL_HDR even if i do setLookDirection for sun from lightEstimate.getEnvironmentalHdrMainLightDirection().. – Donofrio

I didn't find any workaround for this yet. I'm stuck with the same problem as @VadimShved said – Lagoon
