based on interesting lunch discussions with John and others here at the
W3C TPAC meeting, i added the following slide to our wiki. comments welcome.
_Differences with underlying render layers_
- OpenGL, DirectX, others are used as render layers for output o
X3D player which parses .x3d XML files and draws them
- Unlikely that all browsers will implement the same render layer
(OpenGL != DirectX)
- A Canvas3D layer might be helpful to unify calls to the underlying render
layer - but how will it evolve over time?
- Not clear that Web authors are clamoring for ability to program low-level
OpenGl (or similar) source code in Javascript, such models are not
interoperable or composable
- X3D avoids these problems as a declarative scene-graph language available
in XML
all the best, Don
