I added the flying particles in my crowd sim setup to see how it'd look like. I think it looks pretty cool, but there might just be too much activity going on, with all of them flying around and zipping by each other.
I realised that I don't know much about Expressions in Houdini, so, I spent the day following most of these tutorials from the sidefx website, so that I could understand more about the different expressions and what they are,or can be used for. I learned some simple expressions and various variables. I also learnt that the point sop can do alooooooooooooooooooooooooooooot of things. I already use it, but I didn't know it could be used for so many things. One of the tutorials was about standard particles variables, it refreshed my memory about certain variables like $LIFE and $NUMHIT, also the usage of particles IDs using the $ID variable. One of the tutorials also showed how to control the color of the particles based on the distance of the particles from a certain object, I found that pretty useful as I was actually wondering how to do that at first.
One of the tutorials which I thought was cool was splitting a torus into individual faces, then blasting them away, and also coloring the torus using a few expressions.
The one about particles had some usage of particle groups. It also used a bunch of point nodes to control the scale, color and transparency of the objects.
I saw a tutorial on VOPSOPs on the sidefx website and watched it. I still don't quite understand them yet. I think i'll just focus on particles first for now, but eventually I want to know how to use the VOPSOPs to my advantage. I feel more enlightened after learning more about the usage of expressions in Houdini.
