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

Workstation GPU	Cores	Memory	Bandwidth
