<p>The existing X3D profiles were designed for run-time
environments. Since those original definitions, the marketplace
has changed. There is need of an open, standardized formats for
models that supports conversion to and from existing formats such
as FBX, OBJ, glTF, and others. There are some tools that do that
conversion, but tend to be expensive or limited in capability. To
address this hole in the 3D eco-system, I am proposing new
profiles to handle the archive storage for models. The first
proposal is for static models. These are models without
articulation, joints, sliders, etc. The profile supports the way
models are built in the industrial/professional world of games,
entertainment, CAD, and medical -- at least to the best of my
understanding.</p>
<p>The collection of nodes handles output functionality from Maya
and Blender plus other tools. It includes some advanced structures
such as NURBS, CAD, and Volume; and does not include simple
structures as simple geometry (Box, Sphere, etc.). I looked at
what the tools output and could not find instances where simple
structures were exported. This allows important features of the
model (e.g., a NURBS surface) to exist and triangulation to happen
later in the process.</p>
