curve3d's Issues

multilayered textures

support for this will go a long way in making indoor walkthroughs possible. For example a tiled wall
texture can be overlaid with a low-res lightmap texture for the room.

UVs can be handled in two possible ways.

1. multiple uv sets (not supported by obj format?)
2. auto-scale uvs down for lightmap image (harder to account for in modelling software)

3ds file format support

This should definitely be the second file format a3d supports. It's compact (smaller than obj
because it's binary), is industry-standard, and supports all the things that obj does not:

• scene / hierarchy information
• animations & keyframes
• materials
• lights
• cameras
• and more

Here's a great place to start with JS:

Support Internet Explorer

Try both dx transforms and flash backends

any uv's outside the standard box (greater than 1.0 or less than 0). Image should be tiled when this
is the case.

perspective mode functions improperly

http://blogs.answersingenesis.org/adamia/demo.html

on this demo perspective appears to just make the sphere narrower rather than give it true
perspective.

Maintain minified versions of the source

Automate it somehow

Animated texture support

Allow for either an animated gif or single image with multiple frames spread across it.

Face z-sorting has some minor "bugs"

Not sure if this is a bug or just a limitation of the z-sorting algorithm
currently in use. From certain angles, in the robot-dragon demo, the z-
sorting is incorrect in the canvas renderer. I haven't tried the css3 renderer
yet.

Add a flash 10 drawTriangles() backend

Just as a fall-back for browsers that are too slow.

child object shifts when new instance is added

http://blogs.answersingenesis.org/adamia/demos/flyingSaucer/index2.html

If you notice when a new sphere is dropped the shadows of the last one dropped shifts slightly.
Also, as more spheres are dropped the shadow appears more to the left each time (at least for the
first few).

event handling ideas

Two things could make this way more appealing than flash.

1. along with querying the scenegraph (virtual dom), allow querying and event binding using
   whatever js framework they desire (may require framework plugins for custom attributes, etc.)
2. By default for mouse events, if the pixel clicked on is transparent, the event is passed on to any
   dom element(s) behind the 3d image. This would allow you to have 3d objects over selectable text
   or html links for example.

jQuery style scene querying and manipulation

$a3d('mesh.grass[height>5]').scale(0.33);

face/uv shifting

This is more obvious on the robot-dragon demo, but it may be the same
thing I've noticed before. If you rotate the model slowly you can see that the
triangles (or the uv coordinates, not sure which) shift in an inconsistent way. If
they all shifted together that wouldn't be a problem, but they're shifting in
different directions so it almost looks like he's "shapeshifting." I think it is the
triangles that are shifting, not their coordinates, because you can see the shift
in the profile of the body, and the edge of the triangle actually moves.
