MetaVR Photo-Specific 3D Content

MetaVR offers 3D military entity models built using our photographically-specific 3D model convention. The intent of this convention is to create a model that has a one-to-one mapping of photographic elements to unique geometry such that there are no repeating textures.

Available models

	Available photo-specific and hybrid (photo-specific and photo-realistic) models; click Zoom for enlarged images and details about each model.

MetaVR offers for purchase the source data of these models. Each model purchase includes the OpenFlight source data, texture files in editable RGB and PhotoShop formats, and source images in raw format.

Note that some models in the MetaVR 3D content military vehicle library are "hybrids" in their texture makeup; they are approximately 75-80% photo-specific, with the remaining textures photo-realistic. The Buffalo EOD, Cougar EOD, ZILI31H, and Hunter UAV models shown above are examples of this type of model.

Model specification

The specification for building a MetaVR photo-specific model, as shown in the models above, consists of the following criteria:

• Perspectiveless 6- to 10-megapixel digital photographs of all major visible exterior surfaces should be taken from a distance of .5 meters to 5 meters from the vehicle.
• Photographs should be taken from the most recent public military exhibition of the vehicle.
• For armored vehicles, the turret and hull each should be comprised of 2048 x 2048 pixel texture maps constructed from the digital photographs, where each photographic element is assigned to a unique geometric surface (except for the road wheels) i.e., photo specific textures.
• The composite texture map of photographs should result in .004 meter resolution or better (this means an observer should be able to discern details of 4 mm or greater in size).
• Geometry should consist of minimum of 10,000 polygons with five levels of detail (LODs).
• Animated tracks and/or wheels and particle-based dust trails.
• Material codes mapping for the major components of the vehicle to support time-of-day dependent physics-based thermal models.
• The resulting model should have a one-to-one mapping between photographic elements and unique geometry (as result, there should be no repeating textures).
• Mixed-fidelity models can be created that comprise some combination of photo-specific and photo-realistic textures; such models are called "hybrid photo-specific and photo-realistic". In general, this classification is used only when the model is comprised of at least 50% photo-specific content.

Example of model creation

As an example of building a MetaVR photo-specific model, consider the image below taken of a T-90 at an armor exhibition in Europe:

Note that the three additional front side hull plates that are typically mounted in combat for additional protection were removed for the exhibit; they have been added to the MetaVR 3D model as shown below:

For accurate remote sensor verification, all the primary vehicle sensor and self-protection mechanisms need to be modeled in significant detail. Photographic elements of all turret detail shown above have been replicated in the 3D model below:

Compacted soil is evident between the model's track elements as shown in this final image:
