Example

// In a render loop, iterate views from viewerPose
using var viewerPose = frame.GetViewerPose(refSpace);
if (viewerPose != null)
{
    foreach (var view in viewerPose.Views)
    {
        using (view)
        {
            Console.WriteLine($"Eye: {view.Eye}");
            using var projMatrix = view.ProjectionMatrix;
            float[] matrix = projMatrix.ToArray();
            // Use matrix for rendering
        }
    }
