simply we affect the particles from curve 1 to our new 2 radial fields
now we have 2 particle shapes (from curve1 and from curve2) being affected by 3 radial fields
if we compare the new curves created with the initial ones (light green) we can see the tranforms
made by the radial fields
now it is time to practice with multiple fields, and their attributes, on our curve-particle system
first we practice on one curve
the attributes that are manipulated are
magnitude
attenuation
trap inside
trap radius
first we build our curves and then we make them goal for our particles
i decided to manage fewer lines than the previous examples, so we change the emmition
rate to 2 (current situation)
we make layers so as to categorize our stuff
in the goal offset expression in both the particleShapes i changed the numerical data to
for the particles to have more space to interact in the later steps.
next after some experiment with the particles attributes i changed(in the goal weights and
objects menu) the Goal Smoothness to 6.000 and the curve Shape to 0.400
after the source of the script we take the first curves before any fields apply to our
particles
next we insert a radial field and we change its magnitude to 3.5 (repeller) and its attenuation
to 1.7, we make its volume shape to sphere so as to view the a.o.e.
first we test the results in the particleShape1
then we make the particleShape2 to be affected by the field we have created
we can observe that when the particles insert the radial field their Y direction (height) tend to
go to value 0. and some of the particle are pushed away from the field’s source.
after that we insert a new radial field but this time it will be used as an attractor, so its
magnitude will have a negative value. In this case i gave it -5.000, a rather big value in
association with the previous field but that way we can visualize the results more easily, and
understand the forces applied to the particles.
we do the same stuff like if we had 1 curve that would be our goal for the particles
in the first curve we apply the ParticleToCurve script and we see the trails created
in the second curve we apply the same script BUT we change the name : curve_pt (pt stands for the particletrail)
to curve_npt(npt stands for the new particle trail)
if we do not change that name, the points from the previous created curves from the curve 1 will be taken into consideration
for the creation of the curves from the curve 2 and there will be a mess.
when we rename the curves first we change the name from : curve_pt to old
next curve_npt to n_old
. . .
. . .
. . .
next we apply whatever field we like, do the same procedure with the layers and the colors and we have 2 dynamical systems instead of 1
