HoloStreamer: Unity Plugin

For recording, saving and sending camera streamer from HoloLens in real-time

use different invalidation condition

// Invalidation mask for Long Throw
const USHORT mask = 0x80;

// Invalidation value for AHAT 
USHORT maxValue = 4090;

AHaT Mode

// validate depth & append to vector
for (size_t i = 0; i < outBufferCount; ++i)
{
    // use a different invalidation condition for Long Throw and AHAT 
    const bool invalid = (pDepth[i] >= maxValue);
    UINT16 d;
    if (invalid)
    {
        d = 0;
    }
    else
    {
        d = pDepth[i];
    }
    depthByteData.push_back((BYTE)d);
    depthByteData.push_back((BYTE)(d >> 8));
}

Long Throw Mode

assert(outBufferCount == outSigmaBufferCount);
for (size_t i = 0; i < outBufferCount; ++i)
{
    // use a different invalidation condition for Long Throw and AHAT 
    // the most significant bit of pSigma[i]
    // tells if the pixel is valid
    const bool isInvalid = (pSigma[i] & mask) > 0;
    UINT16 d;
    if (isInvalid)
    {
        d = 0;
    }
    else
    {
        d = pDepth[i];
    }


    depthByteData.push_back((BYTE)d);
    depthByteData.push_back((BYTE)(d >> 8));
}
