An important feature of the upcoming FROST particle mesher is its ability to interpolate particle data channels and propagate them to the final mesh. For example, the Vertex Color and the 99 Mapping channels can be used to control parameters like color or surface tension.
In the screenshot below, you can see three simple Particle Flow systems emitting 10K particles over 24 frames.
The first particle system passes through a Torus primitive. A Volume Select modifier on top of the FROST mesh selects the vertices inside the Torus and passes them up the stack as a Soft Selection to control a Relax modifier which produces higher tension and smooths out the final mesh.
The second particle system has a Mapping operator keyframed over time to change its value between black, white and black again. The Mapping is synchronized with the Particle Age and is then converted to a Vertex Selection by the Volume Select using a Vertex Color map. That selection in turn controls the Relax modifier.
In the third example, the Particle Flow has a Collision Test which sends the colliding particles out to a second Event. The first Event has a Mapping operator with a black value throughout, the second Event has a Mapping operator synchronized by Event Duration keyframed from black to white in 10 frames. As result, the particles that collide change their Mapping and thus their Relax value over time...
