TerraStereo - Sophisticated Visualization of Very Large Point Clouds

>> TerraStereo Release Notes

TerraStereo is a stand-along application for visualizing very large point clouds. It uses high-performance graphics boards for rendering huge amounts of points fastly and in high quality. The software enables you to:

  • visualize up to 50 billion points that are organized in a TerraScan project
  • perform visual analysis and quality check in both, small and large scale displays
  • navigate through the point cloud freely or based on TerraScan trajectory files
  • create animations
  • view laser data in stereo mode and create stereo screencaptures
  • easily change between different display channels and point rendering modes
    • elevation, intensity and class coloring
    • color by RGB values
    • shaded surface display
    • point density coloring
    • TerraZ rendering method for masking foreground objects
    • different quality levels for point rendering
  • combine different visualization channels in order to improve the perceptibility of objects in the point cloud
  • switch point classes on/off
  • apply elevation exaggeration to the point cloud for specific analysis tasks
  • measure distances within the point cloud
  • digitize line vector elements and export them to TerraSurvey

Hardware requirements and recommendations

There are some specific hardware requirements and recommendations in order to run TerraStereo in a proper way:

  • minimum of 4 real processor cores, more than 4 are recommended
  • good amount of processor cache memory
  • > 16 GB of RAM
  • fast memory and hard disc access
  • GPU board(s) that are compatible with NVIDIA® CUDA 1.3 or higher
  • fast GPU interface bus and interconnection to system memory
  • higher number of GPU cores speeds up rendering performance
  • higher GPU bandwidth speeds up rendering when 2 identical GPU boards are used
  • > 2 GB of GPU memory recommended
  • dual GPU boards and SLI configurations work but are not recommended
  • NVIDIA Quadro® board is required for stereo display, NVIDIA GeForce® board(s) work for mono display
  • display device that supports quad-buffered stereo display (for stereo viewing)
    • stereo display or projector using DisplayPort or Dual-DVI connection (not HDMI)
    • (optionally) active or passive stereo glasses

GPU recommendations

All GPU boards must be compatible with NVIDIA® CUDA 1.3 or higher.

  • Low-cost solution (low performance, mono display only):
    one GeForce® board
  • Medium-cost solution (high performance):
    one to two high-end GeForce® boards for TerraStereo rendering and one low-end Quadro® board for stereo display
  • High-cost solution (high performance):
    one or two high-end Quadro® boards listed in the following table
