OSV is an advanced, physics-based sensor scene generation software package built on OpenSceneGraph's default OSGViewer application. It provides an example of how to integrate JRM's SigSim and SenSim physics-based sensor modeling libraries with OSG-based rendering applications, and comes with the integration source code.

 Its highly realistic image output is ideal for advanced training system applications and tactical sensor studies. OSV provides high-fidelity simulation of arbitrary imaging sensors in the UV through far IR (0.20-25.0 um) spectrum with highly-optimized, physics-based signature synthesis and Modtran 4.0-based atmospheric propagation modeling.

OSV At-Aperture Radiance Scenes
With JRM’s SigSim signature synthesis and atmospheric propagation library embedded, OSV computes the at-aperture sensor-passband radiances of complex scenes under dynamic environmental and object conditions, such as time of day, time of year, geolocation, weather, entity engine cycle state, trajectory, speed/Mach#, etc.

OSV Sensor Effects
With JRM’s SenSim engineering-level EO/IR sensor modeling library embedded, OSV provides component-level simulation of optics, detector arrays, signal processing and displays for realistic appearance.

Additional Features
OSV allows you to easily create and simulate a dynamic tactical sensor scenario. With its easy-to-use GUI, you can load your 3D terrain database, completely specify any number of arbitrary sensors, atmospheric and weather conditions, and place 3D vehicle or human models in the scene. Mouse and keyboard controls allow you to fly or drive your sensor as attached to a model throughout the database and the software allows you to capture floating-point true radiance images in [W/cm2/sr].
