How would you differentiate V4 from Collada in that case? My understanding is that X3D provides for declarative app development. This is one reason we are moving towards the web, to open X3D up to more app developers. What is important for declarative app development? Protos, Templates, Web Components and associated scripts, essentially *shared behavior*. If you have a virtual world, you might certainly have exactly one of everything. However, it’s easier to instantiate Protos or Templates, I think. The trick is to only mention the creation a few times (once) with templates or web components, and let the environment expand it into multiple instances through templated transforms and parameterization. I don’t want to see 400 ProtoInstances of cylinders in code, unless it’s generated (HTML). X3D *should* be associated with a data format for pure data, like D3.js has several, and transforming pure data into 3D. I know I have different requirements, but I think X3D V4 should be designed for scaling things up—not only shapes and transforms, but coordinates and polygons as well (SRC). Is any other format in position to provide for such scaling without killing memory or diskspace? Models are certainly moving towards SRC. If you are concerned about animation, what’s the best way to provide for animation coming from these tools? We have your proposed nodes. Are these sufficient? Should we start looking more at creating exporters for animation beyond just models? What animation exporters to X3D are already out there?<div class=""><br class=""><div class="">John<br class=""><div class=""><br class=""><div class=""><div><blockquote type="cite" class=""><div class="">On Feb 24, 2016, at 7:55 PM, Leonard Daly <<a href="mailto:Leonard.Daly@realism.com" class="">Leonard.Daly@realism.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

There seems to be some confusion about my statements about not
hand-coding certain things. <br class="">
<br class="">
I have stated that models and animations are not hand-coded anymore.
That statement does not mean it can't be done, but there are many
tools that do it, including open-source ones. There is no way
someone is going to hand-code models such as you can see at
<a class="moz-txt-link-freetext" href="http://www.blendswap.com/blends/index">http://www.blendswap.com/blends/index</a>. Hand coding models to be
printed is also not a good idea because things will probably not
line up correctly.<br class="">
<br class="">
Animation is the same thing. Yes you can animate by hand-coding all
of the motions and deformations, but that is not how it is done. If
X3D is to get any acceptance into the professional marketplace it
MUST work with application generated models and animations. There
will still be some important animations that are hand coded (e.g.,
camera motions, automated systems, etc.). <br class="">
<br class="">
Nothing I have done in working out the V4 proposal precludes
hand-coding of animation or modeling. It does not provide a lot of
convenience features/nodes to make complex work simple. In the
marketplace, it is much simpler to get someone to do the model or
animation in a tool. <br class="">
