Depth Mesh

Depth mesh is the creation of triangle-based meshes surfaces detected by Nreal Light. The mesh is used for real-time occlusion rendering and for collision detection with digital content. Unlike Plane Detection, which only detects planar surfaces, Meshing can detect a variety of surfaces.

Capabilities

Depth mesh expands many AR capabilities.
  • Visualization: Provide visual feedback as users scan their environment.
  • Occlusion: Hide virtual objects behind real ones, especially in larger outdoor environments where Depth-based Occlusion may not be practical.
  • Physics: With the help of MeshColliders, virtual objects and characters interact with the environment and real objects.
  • Procedural Object Placement: Populate the AR world with more flexibility than Plane Detection.

Best Practice

The mesh quality depends on the image texture, related to the scene material, lighting, motion speed, etc.
Good quality:
  • Uniform illumination
  • Move smoothly and slowly
  • Highly textured surfaces: carpets, wallpapers, wood floors
  • The appropriate range of distances: 0.5m to 3m
Poor quality:
  • Moving objects
  • Dark environments
  • Transparent/Semi-transparent or reflective surfaces
  • Thin objects: chair legs, fences
  • Textureless surface: white walls, painted desktop

Device compatibility

Depth Mesh has been fully tested on the following Android phones:
  • OnePlus: 7T / 9
  • SONY: Xperia 5iii
  • OPPO: Find X2 / Find x3 Pro
  • HUAWEI: P30 / Mate40Pro
  • LG: VELVET / V50s / G900N / style
  • SAMSUNG: Galaxy Note20Ultra / Galaxy Note20 / Galaxy S21 5G / Galaxy Z Fold3 5G / Galaxy S20 Ultra
Depth Mesh can also run on devices besides the above, the stability however is not guaranteed. For the complete compatibility list, please refer to Device Compatibility.
