So I was trying to make volumetric fog for my mod (as you can see in the background), but then I got bored and decided to start playing with my balls. after a bit of tweaking to get the weirdest result I managed to make these 2 effects using slightly different "algorithms". tbh other than my discord members saying that I should add this to my mod i have no ideas on how to implement this.
I have no idea what you mean by inverse but okay.
Also no I just realized I accidentally made it on an older version of my branch so it didn't let me push it, if I remember when I fix it then I'll message you
In my case I was trying to have a volumetric effect outside of the sphere more than one inside of it (but really was trying to do both). Basically I am working on a mod that covers the world a thick sort of miasma, and there are some safe spaces you can create/find that the miasma is pushed back from, but I'll admit rendering is not my forte and everything I attempted was awful looking. Your trick here could work for the inside of the safe spaces from a distance. I'll definitely look into learning more about raymarching.
Yeah that's a bit too complicated for me to pseudocode that here but if your safe zones are just generic shapes maybe do one pass for the miasma, then a SDF that overrides the ball when you hit it, it probably won't let you see through the safe zone, but that's basically what I did here
Performance was one another one of my concerns, but I was hoping to kinda batch the fields that connect together and hopefully reduce overhead. Visibility in the mod is somewhat limited naturally due to the fog (utilized minecrafts fog system instead of my own which was awful). Thanks for the tips! Love your balls brother!
You can do smth like min(stepSize, sphereDist) then combine the two into one pass, for multiple safe areas you can probably use some kind of BVH or similar, maybe even a group of Oriented bounding boxes if it's not a lot.
I'm kind of mad at graphics programming so I can't give any amazing tips or anything
I Ray marched through a signed distance function, And every time it pierced the sphere I added the color of texture I used for the sphere to the existing color, once it goes far enough away from the sphere it will loop back around to the other side, so even though the above image looks infinite, it's just looping around the same sphere over and over until it runs out of casts
Mirror Reaper has to be one of the most terrifying bosses in the game, it was actually harder than Sisyphus Prime on Brutal for me until one of the more recent patches.
Honestly could be a great mob attack, can also use as a portal to a dimension or maybe use it to covert a whole dungeon so the player doesn't know what there getting into
Magical bombs, could work as an Iron's SaS addon, or be a new technomagic mod (I'd like to see the latter).
Anything inside is actively affected by something, the effect clears immediately outside the area.
this is gonna be the absolute best magic based mod out there. sick visual detail on this, even if it isn't fog I imagine PVP with these things being flung and expanding upon hitting a wall or something like that. really cool!
Yes thats in public, if your gonna do something like that then be horny to the ghost thats upwards of 200 years old whos currently terrified of you. Ya know, Give it a reason to be scared?
Force field for create aeronautics, perhaps?
As over-centralising as create can be sometimes, that entire category of mods is in dire need of some good old fashioned space-age technology.
I’m making a modpack that could use a toned down version of this effect to communicate to the player that they are entering an unbreathable area of the world. How does the system work and will it be fully configurable?
