[x3d-public] Proposal for New Fields for ParticleSystem

[Holger Seelig]

The new latest of X_ITE comes now with two new fields for ParticleSystem. That are scaleKey and scale fields. They work much like colorKey and color fields.

A user asks me for the ability to scale the particles during the time, basically to make the particles grow from its creation time and then shrink.

Other 3D engines like Unity have this already for a long time.

With the two new fields it is possible to have a curve and finely adjust the size over the time.

New fields will look like this:

inputOutput MFFloat scaleKey [ ]
inputOutput SFNode scale NULL  [Coordinate]

It will work with all geometry types a ParticleSystem can have, even GEOMETRY.

I prepared a very simple example that shows the capabilities of these new fields:

Best regards,
