Yet yet another cube
dojoI made a huge mistake on the last post,
Yet another cube. In that post, I attached a
quick-n-dirty implementation of dojox.gfx3d that work in Firefox only.
Unfortunately, no source code is attached except gfx3d.js and a symbol link to
my home directory. I untared the tar ball, and it worked, of course it just
linked to my working copy! Here is the
current snapshot.
In this implementation, I took the lazy evaluation, thanks to Eugene’s advice:
Once a 3D object is created in dojox.gfx3d.Viewport, only meta is recorded.
The real DOM node is not constructed till the last minute, when
dojox.gfx3d.render is called. That simplify the development and eliminate the
dependencies of SVG and VML renders under the hood.
Above is screenshot in Firefox 2.0 and MSIE 6.0, you can see the inconsistences of the coordination system, we would fix that later. And here are more to consider:
- Scene support so we can apply the world transform in a group of objects
- Texture support: solid and gradient for more sophisticated texture
- Z-order
Once we solve these problem, the next step is just to propagate it to other more complicated objects.
