[x3d-public] Your mission, should you choose to accept it. ComposedShader+ParticleSystem

[John Carlson]

Michalis, Holger, Doug, Don,

On the tails of Holger's message about GPU instancing...

It's easier to send email to you all rather than filing a report on your
websites.

I'd like to get a fairly simple Particle System working with a
ComposedShader (different for each of you).

I am attaching the .x3d file and the shaders.

I've gotten the ComposedShader working for a single sphere for each of
your systems, but getting it working with a Particle System and
ComposedShader seems difficult.

I've gotten the Particle System working in sunrize.

There's a Problem with BoundedPhysicsModel geometry in view3dscene.

Don,

CommandLine doesn't validate the scene AFAICT.

$ java -cp ~/Downloads/X3DJSAIL.4.0.full.jar
org.web3d.x3d.jsail.CommandLine -validate `pwd`/particleflowers.x3d
CommandLine parameter: "-validate" for model validation
parameter: source file particleflowers.x3d filesize 6208 bytes
Parsing using Document Object Model (DOM) based X3DLoaderDOM...
[error] X3DLoaderDOM: Incorrectly handled X3DJSAIL object construction,
current elementObject=BoundedPhysicsModel (BoundedPhysicsModel),
child="Sphere", containerField="geometry", java.lang.ClassCastException:
class org.web3d.x3d.jsail.ParticleSystems.BoundedPhysicsModel cannot be
cast to class org.web3d.x3d.jsail.Shape.Shape
(org.web3d.x3d.jsail.ParticleSystems.BoundedPhysicsModel and
org.web3d.x3d.jsail.Shape.Shape are in unnamed module of loader 'app')
    This error can be caused by incorrect parent-child node relationships
or incorrect containerField values.
    X3D node typing is strict, check or validate your scene graph!
    This error can also be caused by X3DLoaderDOM DOM omissions in
X3DJSAIL. Please report mysterious problems, thank you.

Interesting challenge!
