PLY File Loader

The PLY File Loader plays back point clouds stored as PLY files, in either ASCII or binary format. It can open a single file as a static cloud, or a folder of .ply files as a sequence. Sequence frames are played in filename order.

Device Properties

• File: the .ply file or folder to load.
• Position Units: the units positions are stored in. Automatic treats floating point positions as metres and integer positions as millimetres.
• Sequence: playback settings for folders.
  • Looping: restart from the start frame after reaching the end frame.
  • Frame Rate: playback speed in frames per second.
  • Start Frame / End Frame: the range of frames to play. An end frame of -1 plays to the last file.
  • Current Frame: the frame being displayed. Can be used to scrub through a sequence.
  • Buffer Capacity: the number of decoded frames held in memory.
  • Prefetch Ahead: the number of frames to decode ahead of playback.
• Attributes: how extra per-point properties in the file are imported.
  • Target: the point attribute this property is read into, e.g. Point Scale for per-point sizes.
  • Precision: store values at full precision, or quantised to 16 or 8 bits to save memory and network bandwidth.
  • Range Min / Range Max: the range of values preserved when quantising.
