By taking advantage of core capabilities, Vega Prime is designed to facilitate the development and deployment of applications that require very large or complex databases. High performance levels are guaranteed by optimizing the loading and organization of large datasets through the dynamic paging of “tiles” and user definable paging centers or Areas of Interest. Vega Prime offers optimized rendering that is fully customizable and scalable to take advantage of available resources.
With its latest drivers, NVIDIA has included a Global Preset tailored to the Presagis suite of visualization tools within the control panel.
The Presagis Worldwide database (WWDB) is a synthetic database of the world in the open Common Database (CDB) format.
Key features and enhancements in Vega Prime 5.0 provide better performance within your visualization and simulation applications through improved utilization of system resources, better handling of data, and more effective tools that enable users to clearly identify bottlenecks that could affect performance. Vega Prime delivers cross-platform, 60hz deterministic air and ground simulation applications that are completely customizable, scalable, and leverage open standards such as CDB and OpenFlight™.
Performance statistics are now easier to read as well as more accurate in identifying and diagnosing performance bottlenecks, whether they are based on scene content, runtime configuration settings, or hardware. This capability allows you to get your application up and running quickly ensuring the highest performance possible.
A new paging strategy now allows for improved performance by parallelizing the creation of content in the scene from the CDB data on disk.
Numerous improvements have been made to improve Vega Prime’s utilization of the available system resources available. Vega Prime now supports configurable resource management for textures, vertex buffer objects (VBO), and shader applies, allowing the user to stabilize the overall draw time. Improved state sharing significantly reduces the chance of detrimental memory growth and performance and stability issues associated with running out of memory. The performance of the memory allocators has been enhanced in Linux resulting in much more stable thread behavior ultimately yielding more predictable frame rates. Users also now have the ability to specify a thread priority and processor for many additional service threads in LynX Prime providing greater flexibility in configuring the system for efficient processing and stable frame rates.
Vega Prime now provides native configuration and support for synchronization of swap buffers from multiple channel/application windows which allows for frame-accurate synchronization of displays while utilizing hardware to minimize latency and provide synchronization to the same pixel rate ensuring the output pixels are in complete lock-step across multiple channels.
Vega Prime 5.0 includes new features that allow you to deliver more realism in your simulations, as well as maximize re-use of existing content by enhancing your existing databases. With support for SpeedGrass™ technology from IDV and improved Hyper-Texure Support, higher resolution imagery and ground-level content can be added to your applications without having to invest in new imagery, saving you time and money.
Now included with the SpeedTree® for Vega Prime module, which provides features that facilitate the definition and rendering of high density trees within a Vega Prime application, is the ability to generate wind-driven grass effects on OpenFlight databases using SpeedGrass technology from IDV, allowing you to add more realism to your simulation in situations where the viewpoint is near the ground.
The image below shows SpeedGrass in Vega Prime.
Vega Prime not only supports the use of very high resolution geo-specific imagery, but also provides the ability to actually increase the detail available through the use of additional geo-typical levels of imagery. It is now possible for users to apply multiple Hyper-Textures to a CDB database, with the ability to configure the texture to apply based on the material classification at any given location. This provides more realistic scenes, automatically, based on the existing material data in the CDB.

The addition of support for 64-bit Windows 7, Common Database (CDB on Linux, and geo-centric TerraPage database format make Vega Prime 5.0 one of the most flexible and adaptable 3D visualization toolkits available on the market today. Maximize interoperability, reusability, and cost savings by leveraging open standards across a wide variety of platforms, giving you even more power to create your own custom visualization applications.
Vega Prime now supports the use of the 64-bit Windows 7 Operating System with the VC9 compiler. Platform support for Vega Prime 5.0 includes the following;: Windows 7 32-bit VC9, Windows 7 64-bit VC9, Windows XP Pro 32-bit VC9, and Linux 64-bit.
Presagis Visualization products include as a core capability the loading, paging, and rendering of the scene content natively in CDB (Common Database) format. CDB is now supported in both the Microsoft Windows, and Linux OS in addition to the existing support of OpenFlight, MetaFlight, and TerraPage databases. CDB dramatically improves the maintainability and reusability of content by providing a means to use source data directly in many applications without modification to the database itself.
Vega Prime 5.0 uses the system default web browser which improves the overall readability as well as search capability available when using the HTML Help or Reference pages.
Vega Prime now supports TerraPage archives using a geocentric coordinate system, a capability which was added in a recent version of Terra Vista. TerraPage now supports round earth projections offering better precision and improved large area support.
Vega Prime now uses the GLSL shader language instead of Cg® internally which provides increased flexibility for users. Users may still use their own shaders written in whichever language they prefer to replace default Vega Prime shaders.
Vega Prime provides the loading, paging, and rendering of the scene content in CDB format as a core capability. The Vega Prime Marine module is now supported in CDB and provides a high performance native wave model that allows for the control of sea states, including distributions of direction, height, wavelength, and alignment with the wind.
Vega Prime now supports the ability to operate on Windows 7 OS platforms.
Maintaining support for new and existing industry standards, Vega Prime now offers out-of-the-box integration with the following standards:
Vega Prime provides the loading, paging, and rendering of the OTW (Out The Window) scene content in CDB format as a core capability. CDB dramatically improves the maintainability and reusability of content by providing a means to use source data directly in many applications without modification to the database itself.
Vega Prime includes the integrated support for the DIS/HLA communication protocols. This capability is included in the base configuration of the product, includes support for Windows and Linux platforms, and is compatible with both MÄK and Pitch RTIs.
New features have been developed to provide improved realism, training value, and usability, including:
Vega Prime provides the ability to easily create, define, and render helicopter-based special effects. Users can quickly and easily define and represent blade, rotor wash, and rotor dust effects.
This capability provides the ability to include dynamic shadows in the scene based on either the celestial bodies (sun/moon) or a user-defined light source. The ability to define shadows based on a user-defined light source gives increased control and flexibility to the types of applications that can benefit from the use of dynamic shadows.
Improved workflow and performance is delivered specifically to address Terra Vista generated content that includes Smart Mesh technology. Smart Marsh provides users with the ability to match terrain tile edges along multiple LODs, preventing cracks and visual anomalies in the database.
Allows for rapid application prototyping and modification, meaning that you can see changes within the application as you make them.
Applications configured and developed on one platform may be deployed on another without code modification.
Provides the capability to render extremely high resolution imagery without affecting performance.
Create correlated visual and sensor displays.
Allows you to mix and match necessary feature sets or to create your own custom functionality within the Vega Prime environment.
Offers maximum flexibility within other application frameworks.
