Note:

The run-time and developers' rights for VR-Forces customers vary from vendor to vendor. Please read this section carefully to understand which rights are included with VR-Forces licenses, and which rights require additional third-party licenses.

SilverLining

VR-Forces uses SilverLining software and content to compute lighting and to render the sky, clouds, sun, and moon. SilverLining is developed by Sundog Software (http://www.sundog-soft.com).

Most VR-Forces customers do not need to buy a SilverLining license of any kind. In general, a VR-Forces customer has the right to use the SilverLining technology that is built into VR-Forces in any VR-Forces-based application (including custom applications built using the Toolkit). However, there are two exceptions:

• If you want to extend or change the way that MÄK has integrated SilverLining into VR-Forces by writing directly to the SilverLining API, then you need a SilverLining Developer's License.
• If you are building a commercial video game or other "mass-market" (consumer-level) commercial product on top of the GUI API, and the resulting product includes the SilverLining functionality, then you need a SilverLining Developer's License.

SilverLining libraries, textures and other graphics resources are distributed in the VR-Forces package solely so that VR-Forces can use them. Use of SilverLining software or content outside of VR-Forces-based applications is not permitted by the VR-Forces license.

GL Studio

VR-Forces uses GL Studio software and content to render interactive cockpit instrumentation displays. GL Studio is developed by DiSTI (http://www.disti.com).

VR-Forces is delivered with several generic cockpit displays. You can use the built-in cockpit displays in any VR-Forces-based application (including custom applications built using the Toolkit), without a GL Studio license of any kind.

If you want to build custom cockpits using the GL Studio editor or GL Studio API, you need a GL Studio Developer's license. If you want to execute custom cockpits in VR-Forces-based applications (regardless of whether the custom cockpits are built by you or a third party), you need GL Studio Run-Time licenses.

GL Studio libraries and graphics resources are distributed in the VR-Forces package solely so that VR-Forces can use them. Use of GL Studio software or content outside of VR-Forces-based applications is not permitted by the VR-Forces license.

DI-Guy

VR-Forces uses DI-Guy software and content for human character animation. DI-Guy is developed by Boston Dynamics (http://www.bostondynamics.com).

VR-Forces comes with DI-Guy functionality built-in and with a large set of DI-Guy characters, appearances, and animations. A VR-Forces customer does not need a DI-Guy license of any kind to use DI-Guy animated characters in a VR-Forces-based application (including custom applications built using the GUI API).

However, you need a DI-Guy Developer's license if you want to:

• Develop new character types, or alter the geometry, appearances, textures, or motions of DI-Guy characters.
• Directly access the DI-Guy API to modify or extend the way that VR-Forces uses the DI-Guy API or access DI-Guy functionality that MÄK has not already integrated into VR-Forces.

DI-Guy libraries, models, textures, motion files, and other graphics resources are distributed in the VR-Forces package solely so that VR-Forces can use them. Use of DI-Guy software or content outside of VR-Forces-based applications is not permitted by the VR-Forces license.

SpeedTree

VR-Forces uses SpeedTree software and content for animated real-time 3D foliage and vegetation. SpeedTree is developed by Interactive Data Visualization (IDV) (http://www.speedtree.com).

A VR-Forces customer does not need a SpeedTree license of any kind to use the SpeedTree functionality that is built into the VR-Forces applications that MÄK delivers. You may build and run plug-ins to our out-of-the-box applications without a SpeedTree license, as long as your plug-ins do not need to directly access the SpeedTree API.

However, you need a SpeedTree Developer's license if you want to:

• Write a plug-in that uses the SpeedTree API directly to extend or modify the way that SpeedTree is integrated into VR-Forces.
• Use the GUI APIto develop new applications, and you want your applications to include SpeedTree functionality.

SpeedTree libraries, models, textures, and other graphics resources are distributed in the VR-Forces package solely so that VR-Forces can use them. Use of SpeedTree software or content outside of VR-Forces-based applications is not permitted by the VR-Forces license.

3D Models, Terrain, and Graphical Content

VR-Forces includes a rich set of 3D models for vehicles, weapons, cultural features and urban clutter (signs, barriers, lampposts, and so on). It also includes several sample terrain databases to help you get started with VR-Forces, and to help demonstrate VR-Forces. Much of this content is derived from 3D data that we have licensed from third parties:

• Many of the high-quality vehicle models come from Simthetiq (http://www.simthetiq.com).
• Some models come from Real DB (http://www.realdb.qc.ca/company)
• Some of the middle-eastern building models and urban clutter objects that are used in our sample terrain databases were licensed from Turbosquid (http://www.turbosquid.com)
• The TerraSim_SampleUrban terrain database comes from TerraSim (http://www.terrasim.com)
• The HarrisAfghanVillage terrain database was created using source data from Harris Inc.
• The Berkeley Database was developed by Terrex (now Presagis) (http://www.presagis.com).

All of this content is distributed in the VR-Forces package solely so that VR-Forces can use it. Use of any of the VR-Forces models, textures, terrains, or other content outside of VR-Forces-based applications is not permitted by the VR-Forces license.

OpenSceneGraph

VR-Forces uses OpenSceneGraph for its underlying scene graph representation, rendering, file loading, and many other capabilities. OpenSceneGraph is an open source, cross-platform graphics toolkit for the development of high-performance graphics applications. The OpenSceneGraph source repository is maintained by Robert Osfield at http://www.openscenegraph.org/projects/osg. It is distributed under the OpenSceneGraph Public License (OSGPL), which is based on the GNU Lesser General Public License (LGPL).

osgEarth

VR-Forces uses osgEarth to import streaming terrain elevation and imagery data. The data can be streamed from external servers and sources or from a directory on the computer running VR-Forces. osgEarth is an open source plug-in to OpenSceneGraph, maintained by Pelican Mapping at http://osgEarth.org. osgEarth is distributed under the GNU Lesser General Public License (LGPL).
