[x3d-public] [x3dom-users] PointProperties in X_ITE

[Andreas Plesch]

x3dom has the similar ParticleSet node:

https://raw.githack.com/x3dom/x3dom/master/test/regression-suite/test/cases/particleSet/particleSet.html

sizes are given per particle, rendered size is always scaled with
distance from viewer, emissive and texture are multiplied, texture is
mapped to size of particle, opacity falloff from center to
circumference, unimplemented option for particle shapes other than
circles.

Another option is a custom shader:
