System Requirements

    InterBridge requires no installation and administration. The product has no specific system requirements, yet allows visualization of 3D models of large-scale processing facilities using ordinary office PCs. The minimum requirements are listed below:

  • OS: Microsoft Windows 8/7 86, 64; Microsoft Vista 86, 64, Microsoft XP 2000 86, 64.
  • Processor: Intel Pentium/Celeron (or compatible), 450 MHz or higher.
  • VGA: OpenGL 1.1-supported and higher.
  • Random-access memory: 128 Mbyte.
  • HDD: 4MB install.

Comparing with Analogous Software

    InterBridge provides excellent performance benchmarks of large-scale projects in oil, gas, chemical, and defense industries. Our benchmarking reported the following results.

  • Most compact software: The InterBridge distribution package is only 2MB, hundreds times smaller than competitors; see figure below.

  • Fastest operations: InterBridge opens 3D models of large facilities (consisting of several hundred thousand elements) quickly, literally flying even on standard office computers. The software instantly opens the model, and then makes is ready for operators to manipulate the model in any way. Other software systems are sometimes unable to handle giant models, or simply cannot open models of this type. See figures below.

  • The most productive software: InterBridge is able to manipulate very large 3D models (made of several hundred thousand elements) requiring a significantly smaller amount of memory; see figure below.

    The results come from a comparative analysis carried out by NEOLANT staff using the following hardware and software configuration:

  • Hardware: 3.4GHz Intel Core i7-4770 with 8GB RAM and NVIDIA GeForce GT640 4GB graphics board running on 64-bit Windows 7
  • Software: InterBridge 2015.2 2015.828, compared to Autodesk Navisworks Manage 2016 (64x) 13.0.1240.5, Bentley Navigator V8i (SELECTseries 6), and Intergraph SmartPlant Review 2015R1 (
  • 3D Model: 842MB with 131,016 elements
