AMRDEC has developed the Multi-spectral Advanced Volumetric Real-time Imaging Compositor (MAVRIC) prototype
for distributed real-time hardware-in-the-loop (HWIL) scene generation. MAVRIC is a dynamic object-based energy
conserved scene compositor that can seamlessly convolve distributed scene elements into temporally aligned physicsbased
scenes for enhancing existing AMRDEC scene generation codes. The volumetric compositing process accepts
input independent of depth order. This real-time compositor framework is built around AMRDEC's ContinuumCore
API which provides the common messaging interface leveraging the Neutral Messaging Language (NML) for local,
shared memory, reflective memory, network, and remote direct memory access (RDMA) communications and the Joint
Signature Image Generator (JSIG) that provides energy conserved scene component interface at each render node. This
structure allows for a highly scalable real-time environment capable of rendering individual objects at high fidelity while
being considerate of real-time hardware-in-the-loop concerns, such as latency. As such, this system can be scaled to
handle highly complex detailed scenes such as urban environments. This architecture provides the basis for common
scene generation as it provides disparate scene elements to be calculated by various phenomenology codes and
integrated seamlessly into a unified composited environment. This advanced capability is the gateway to higher fidelity
scene generation such as ray-tracing. The high speed interconnects using PCI Express and InfiniBand were examined to
support distributed scene generation whereby the scene graph, associated phenomenology, and the scene elements can be
dynamically distributed across multiple high performance computing assets to maximize system performance.
