Accessing left and right IR images in Unity

[ayogan2]

Hello,

I'm trying to get the left and right IR images from the leapmotion within Unity, to show sided by side and to do some stereo image processing.

I followed the example code listed at https://forums.leapmotion.com/t/get-ir-camera-images-in-unity/7473/3 and I'm able to see the left IR camera image and update it continuously. When I try to get the right IR camera image by changing to
tex2D.LoadRawTextureData(args.image.Data(Leap.Image.CameraType.RIGHT));
I still continue to get the left IR camera image. Is there a trick to access the right IR image?

Here is a screenshot of what I'm getting. The code on the left quad is set to use Leap.Image.CameraType.LEFT and the quad on the right is set to use Leap.Image.CameraType.RIGHT, but both are showing the same view.

On the 4.4.0 SDK documentation I see something about using the ByteOffset() method to access a specified camera, but unsure how to use it here. Any examples or pointers would be greatly appreciated

For anyone else looking to solve this problem in the future - the key is to create a byte array that is twice the size of the image and using Buffer.BlockCopy to write into the top and bottom portion of the image from each camera respectively.

    int image_size = (int) (e.image.leftImage.width * e.image.leftImage.height * e.image.BytesPerPixel);
    byte[] image_buffer = new byte[image_size * 2];
    Buffer.BlockCopy(e.image.Data(Image.CameraType.LEFT), (int)e.image.ByteOffset(Image.CameraType.LEFT), image_buffer, 0, image_size);
    Buffer.BlockCopy(e.image.Data(Image.CameraType.RIGHT), (int)e.image.ByteOffset(Image.CameraType.RIGHT), image_buffer, image_size, image_size);

And then apply this byte array to your Texture2D (Remember the Texture 2D should also be twice the size). You would then see the left and right IR camera images on a single texture on a single quad. Hope this helps.

I'm sorry,I don't quite understand what "e" means, can you explain more? thanks

Leap.ImageEventArgs is the "e",I looked at the source code and I saw could it be this?
