[x3d-public] Proposed new Profile

[John Carlson]

Leonard, this is an important work.   It shows what can/should be in a
model which is easily transformed to/from an alternative format.

Are we planning on writing import conversions for X3DJSAIL?  In the same
packages/classes or different packages/classes?  I was going to convert
JSON to Java DOM, but I can be redirected to a more important import.

Will the converter(s) have add-on packages for Box, etc.?

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.

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.

The details are at http://realism.com/blog/proposed-x3d-profile-static-model.
The post includes a list of included nodes sorted by their profile.
