I see it increasing because HTML Scripts can easily add nodes to the DOM. There have been several discussions on the topic of PROTOs. I see a proto-expander or MACRO as being a great addition to V4. It is also possible to easily provide that sort of service via an HTML Script or new custom-implemented node.

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 class=""><blockquote type="cite" class=""><div class="">On Feb 24, 2016, at 7:55 PM, Leonard Daly <<a moz-do-not-send="true" href="mailto:Leonard.Daly@realism.com" class=""></a><a class="moz-txt-link-abbreviated" href="mailto:Leonard.Daly@realism.com">Leonard.Daly@realism.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div bgcolor="#FFFFFF" text="#000000" class="">There seems to be some confusion about my statements about not hand-coding certain things.<span class="Apple-converted-space"> </span><br class=""><br class="">I have stated that models and animations are not hand-coded anymore.
