Virtual Reality Scene Generator (VRSG)
MetaVR™ Virtual Reality Scene Generator™ (VRSG)™ is a Microsoft DirectX-based render engine that provides geospecific simulation as an image generator (IG) with game quality graphics. VRSG enables users to visualize geographically expansive and detailed virtual worlds at 60Hz frame rates on commercially available PCs.
Using Microsoft commercial standards, VRSG provides real-time, single- or multiple-channel visualization of virtual environments, dynamic moving models, and special effects on the latest commercial 3D graphics
accelerators, while providing such advanced visual features as full-scene anti-aliasing and continuous level-of-detail morphing.
As a DIS-based application, VRSG is fully interoperable with other DIS-compliant applications through DIS or CIGI, on systems ranging from laptops to immersive domes.
You can use VRSG as:
A dedicated computer
image generator, coupled to an external simulation host in single-
or multiple-channel mode. As an IG, VRSG supports the features that are typically required for flight training, driving simulations, and many other applications.
- A standalone DIS stealth
visualization tool, providing real-time or after-action analysis of distributed simulation exercises.
- Self-contained first person shooter to simulate individual combatants, JTACs, or forward air controllers (FACs).
- Self-contained UAV camera payload operator to render simulated HD UAV payload video and to stimulate video players such as a ROVER.
VRSG software is Microsoft-based; it uses Windows, DirectX,
and is written in C++. As an executable-ready render engine, VRSG supports but does not require programming for use. Configuration files and interface protocols provide users with the ability to control basic components of the render engine. Developers can use the plugin interface to augment the functionality of the render engine with their own low-level features.
- Asynchronous texture paging technology for visualizing high-resolution, photo-realistic databases at 60 Hz; can address up to 2 TB of texture in real time.
- Database geometry paging, level-of-detail blending, decoupled terrain and texture level-of-detail.
- Dynamic lighting and time-of-day conditions, light-point based star fields, horizon glow, ground fog, and multiple sky models.
- Ephemeris model for sun and moon position, and moon phase.
- Multi-texture techniques such as normal maps, shadow maps, light maps, and decals.
- Volumetric clouds and storm cells with optional volumetric precipitation effects.
- Multiple atmospheric layers including ground fog and haze with sun-angle dependent density and color.
- Object-on-object dynamic shadowing for applications such as tanker refueling.
- Full-featured light points that respond realistically to visibility conditions.
- Up to 20 independent, concurrent, steerable light lobes for video cards that support Pixel Shader Model 5.0.
- User-extendable particle effects that respond to wind: dust trails, contrails, tactical smoke, and blown sand or snow.
- Dynamic cratering, deforming terrain surfaces to represent craters resulting from munitions impact. Users can associate various crater radius and depths with differing munition types. On receipt of a detonation event, VRSG can dynamically
hyper-tessellate the local terrain surface to the degree needed to capture the crater's
- Conversion utilities for FBX models and OpenFlight databases and models.
- Full mission function support to include height above terrain, laser range, line-of-sight (intervisibility), and collision detection.
- Significant Common Image Generator Interface (CIGI) support.
- Native high-performance 3D human character render engine; no third-party software required.
- Support for synchronized multiple channels and multiple viewports per channel.
mechanisms for adding 2D overlays to the 3D display.
- Edge blending and distortion correction support of third-party solutions such as Scalable Display Technologies and VIOSO.
- Multiple degree-of-freedom hardware tracker
support for controlling the position and/or orientation of the
- Physics-based IR simulation featuring on-the-fly classification of geoscientific visual spectrum imagery. The sensor simulation responds to environmental conditions and diurnal cycles. Includes a radiance-based automatic gain control (AGC), manual level/gain override, and noise as a function of dynamic range. Mid-range and far IR wavebands are supported to model thermal imagers.
- Notional infrared (IR) simulation featuring dynamic hot-spots, user-controlled intensity as a function of material and time-of-day.
- Post-processing effects to include noise, blur, depth-of-field, level, gain, polarity, digital zoom, and AC banding.
- Electro-Optic (EO) simulation mode.
- Night Vision Goggle (NVG) stimulation modes.
- Radar simulation to support applications such as F-16 DRLMS, SAR, and ISAR, displays for UAVs, or similarly equipped platforms.
- Game-level interface that enables users to add and manipulate 3D content from the content libraries to build up culture for dense areas of interest and for scripting activities of characters and vehicles on the terrain.
- Ability to create dynamic pattern-of-life scenarios to play back in VRSG.
- Support for the MUSE VIDD V2.4 for high-fidelity UAV training.
- Built-in UAV sensor payload model allowing any DIS airborne platform to be used as a UAV, for situations when a notional UAV will suffice for your training needs.
- Real-time HD H.264 video generation with embedded KLV metadata using STANAG 4096-compliant EG 0601 or MISB 104.5 standards.
- Built-in HUDs for several UAV platforms (available in domestic release only).

MetaVR provides a 3D terrain-creation product that complements VRSG,
Tools for Esri ArcGIS, which uses elevation points and imagery as
source data in a familiar GIS interface. MetaVR Terrain Tools work hand-in-hand with VRSG to provide rapid
terrain creation and high-speed visualization.
