HoloLens 301: Advanced Mixed Reality Development and Best Practices
summary
Shows working HoloLens code: Unity project on GitHub, spatial mapping renderer + spatial mapping collider for physics, gaze ray raycasts to place objects, and a hand proximity interaction that reads TryGetPosition world coordinates and interpolates a blendshape based on collider penetration. Mentions spatial mesh update delay ~2.5s, bounding volume 4×4×4m, MRC capture dropping to 40 fps, remote depth streaming at ~3–6 Mbps with ~10–20 ms latency, and recommends world anchors, custom shaders, and model reduction.
