LEVERAGING INVESTMENTS FOR ALLWe work to make new capabilities and technology features available to our entire user base whenever possible. This community-driven approach ensures that we share ideas, feedback and the cost of software development. Ultimately, we think beyond short-term requirements, striving to be disruptive in both our technical innovation and business approach. |
VBS in Action | IED DetectionThe ADF called on BISim to deliver a protected route clearance training capability for situations that would be too dangerous for live training. |
OUR CUSTOMERSOur focus is firmly centered on serving the defense industry. That focus has helped our flagship product VBS3 grow to be the most widely used desktop training package among military organizations. Through military user group meetings held annually at key industry events, our customers influence our product roadmap and present new training challenges for us to help them address. By staying close to our customers, we make sure their requirements stay at the center of all we do. OUR TEAMBISim’s staff is bohemian at heart. We’re a mix of adventurers, creatives, and unorthodox thinkers. Our team comes from military service, while others come from the video game industry, and still others bring years of business acumen from the broader software and technology industries. Together, we all share a common passion for making great games to train warfighters. |
VBS in Action | Training ExercisesThe U.S. Army’s Joint Multinational Simulation Center in Grafenwoehr, Germany, is a high-volume facility. JMSC uses VBS3 for a wide range of training exercises. |

PRODUCT PORTFOLIO
BISim’s product portfolio enables users to create, simulate and visualize realistic multi-domain, battlespace training scenarios to help enhance warfighter readiness.
From desktop simulation and image generation to terrain development and editing to cutting-edge AI and XR, we offer a comprehensive portfolio for your simulation and training needs.
The BISim team has a 16 year heritage in delivery of high-fidelity, game-based simulation using the VBS engine. Leverage the following applications, all built on the VBS platform, to immerse trainees in tailored and engaging virtual environments.
Simulation
Our flagship virtual desktop trainer VBS3 is used in 59 countries for tactical training, experimentation and mission rehearsal. BISim’s next generation desktop trainer VBS4 is an all-in-one application with whole-earth rendering for myriad multidomain collective & individual training use cases, and tools for easy terrain editing and mission planning.
Visualization
Deploy VBS Blue whole-earth rendering technology with game-like visuals on VR, AR, MR & XR devices or traditional multichannel simulators, driven by either CIGI-compliant hosts or VBS4. Our whole-earth image generator VBS Blue IG leverages video-game technologies to bring high-fidelity game graphics to military simulation and training.
Terrain
Develop highly detailed and accurate geo-specific virtual environments with TerraTools from TerraSim, a BISim company. Use the VBS World Server with VBS4 and VBS Blue IG to stream terrain data layers to applications locally or from the Cloud. Streamline enterprise-wide terrain generation with cloud-capable Mantle ETM that delivers an end-to-end solution with your data, processes, servers, and runtimes.
VBS3 is a comprehensive training application that provides a high-fidelity 3D virtual environment for land, air, and sea collective training and mission rehearsal. DESIGNED FOR DEFENSEShaped and refined by over 15 years of customer feedback, VBS3 is the de facto standard in game-based military simulation and meets hundreds of training use cases. STANDARDS-BASED AND TRUSTEDVBS3 interoperates with legacy simulations, protecting and extending existing investments in live, virtual and constructive training technologies. It has been fully vetted by Information Assurance experts and has received certificates of networthiness from U.S. Department of Defense organizations. |
VBS in Action | Games for TrainingVBS3 is the flagship of the U.S. Army’s Games for Training program. VBS3 is accredited by the U.S. Army for use on more than 100 training tasks. |
WHAT IS AN IG?An image generator (IG) provides the visual data (such as terrains, buildings, weather, models, etc.) for multi-channel simulators. Driven by a host simulation, IGs enable many views for different screen configurations so simulators can replicate views and sensors from inside tanks, helicopters, and ships. VBS Blue IG is a state-of-the-art, WGS-84 round-earth, blended procedural and imagery-based visualization solution designed for part-task trainers, VR/AR solutions and full-mission simulators. WHAT IS CIGI?CIGI (aka the Common Image Generator Interface) is a set of simulation industry standards by which image generators and hosts are developed, so that different systems interoperate efficiently and effectively. VBS Blue IG supports CIGI, which has enabled BISim to integrate with other simulations for the land, sea, air and space training domains. WHAT IS A HOST SIMULATION?A host tells the IG what happens during the simulation and what participants should see. It communicates with different, interconnected simulators, and “talks” with each connected simulator to make sure visuals match each other in different systems. VBS Blue IG works with any CIGI-based simulation host or VBS3, which offers seamless correlation. |
VBS in Action - JTAC TrainingWith VBS Blue IG as part of QuantaDyn’s JTAC Trainer, JTACs are able to target buildings and vehicles in the simulation, call for close air support, and conduct battle damage assessment in a high fidelity, whole-earth virtual environment. |
