Re: Starting Our Mission

I think the question is mostly about what declarative webvr will be capable
of. If it follows a DOM model, one imagines a mostly static, event-driven
WebVR system, which is quite different from the typical web game. A key
issue will be what the dom model for 3d does with "shapes". In standard web
dom, you are working with 2d boxes (unless you're pioneering regions). In
contrast, 3d has much more complex shapes with ill-defined properties (e.g.
"bounding box" compare to "box"). What is a "border" around a shape?

To make things work best with the DOM, one would have to define 3d
properties more like CSS and less like WebGL. The 3d equivalent of a
"style" property would be mind-blowingly complex, with many solutions in
current 3D systems to choose from.

It could be that things like picking a 3d object, pretty complex in webgl,
are best rationalized by some equivalent of gesture events. A common way to
select is by focused gaze. However, the integration of gamepad API argues
for a much more complex selection of "gestures".

The current systems are wrappers around WebGL, and therefore reflect 3d
modeling assumptions instead of website navigation.
