Leap motion Raw Image Data SDK differences

[drezta]

I like a few others on here have wanted to play around with the raw image data.

following the instructions I believe the following should get both images when OnImageRead is assigned to the ImageReady callback:
Texture2D leftEye;
Texture2D rightEye;
public RenderTexture renTexL;
public RenderTexture renTexR;
byte[] bs_l;
byte[] bs_r;
void OnImageReady(object sender, Leap.ImageEventArgs args)
{
if(leftEye == null)
{
leftEye = new Texture2D(args.image.Width, args.image.Height, TextureFormat.R8, false);
}
if (rightEye == null)
{
rightEye = new Texture2D(args.image.Width, args.image.Height, TextureFormat.R8, false);
}

    bs_l = args.image.Data(Leap.Image.CameraType.LEFT);
    if (bs_l != null)
    {
        leftEye.LoadRawTextureData(bs_l);
        leftEye.Apply();
        Graphics.Blit(leftEye, renTexL);
    }
    bs_r = args.image.Data(Leap.Image.CameraType.RIGHT);
    if (bs_r != null)
    {
        rightEye.LoadRawTextureData(bs_r);
        rightEye.Apply();
        Graphics.Blit(rightEye, renTexR);
    }

if (bs_l == bs_r) Debug.Log("WHY!");
}

However on execution both byte[] are the same no errors are reported.
Can one of the devs explain what is happening and update the documentation to clarify this behaviour?
args.image.Data() requires a camera type a a parameter, why is this if it makes no difference?

We would be really interesting to know more about your use case and what you are wishing to do with the image data. We'll separately look at the issue. If you can share any information about what you are developing and how you plan to use the image data in this please feel free to share here or email me at support@ultraleap.com if you are concerned about sharing this is a public space.

Simply put, after bashing my hands on a desk once too often while using the pimax 8k + leap motion adapter I thought I would use a computer vision library to give a warning.
The library needs seperate stereo images which it can then compare in a compute shader.

In reality, bs_l = args.image.Data(Leap.Image.CameraType.LEFT); already contains the two images (640x240 for 2x(320x240)). The code doesn't run as expected, but you can already use the current SDK to handle left and right image, just start at the good index for right image. Good luck!
