[x3d-public] Fwd: A Layer/Layout yottzumm/coderextreme example scene to talk about

[John Carlson]

I believe that’s a hardware issue unless one is doing software rendering.

Some people want to make browsers for a spatial internet.

How does one do GDI+ and DirectX at the same time?  Direct2D and DXGI?  Is
that cross-platform?  Maybe we should learn those APIs?

"What .. want to use?"
Perhaps the most flexible arrangement is if each technology layer can be
sandwiched / has a top entry and bottom exit in a stack / is stackable /
has stack interfaces to other technology layers.
X3D has some ways to enter from HTML or from operating system on the top.
But no good exits on the bottom, so limits itself to being the bottom of
the stack. Fix that and X3D becomes a layer that can interleave with other
technology layers in a deep, recursive stack.
