First post:
Trying some weird stuff on this one, but who doesn’t like some challenge ?
I’m trying a “partixel” approach on this one, here I use my particles as screen pixels that are raytracing the scene You can see me changing the resolution on the gif.
I know this type of effect can be achieved through post-processing but I find it quite funny to try that with particles.
Next steps:
Animating a whole startup/end
Finding a nicer mesh and texture, maybe animated
Polish here and there
Here you can see the “particle clip-plane” formed when I pause the system:
This is a full #popcornfx v2 effect, 100% particle !
The basic idea is finding your viewport resolution and using you camera datas (position, vectors, etc.) to stick your particles to a clip-space transform. Depending on the effect, you might need some tweaks, here i’m using a continuous spawn setup so my particle are constantly spawning and dying and ordering themselves on the camera plane, so it acts like a “scanner”, from bottom-left to top-right
From there I’ve got the screenspace plane, then I do some raycast in the scene from camera position to particle position and modulate my particle color based on the result (if the ray hits something, give the particle it’s color, if not make it transparent).
This effect is heavily based on Julien Bilalte’s implementation of particle raytracing inside PopcornFX v1.
I was searching for meshes to use on Sketchfab and I stumbled upon Geoffrey Marchal’s post of this nice Ganesha statue so I went using it and imagining a “futuristic antique store” located somewhere in India.
Here is a gif of the spawning part, still WIP:
So here I spawn 3 different partixel layers at the beginning with different resolutions so I can have this nice “resolution update/refining”.
Here’s a more HD video of the effect running in the editor:
Amazing! Right with Assimbly, yellow is better. Maybe you can replace the border bars by a ribbon that follow the outline of the box in every side, or other thing, but without is better.
this is RAD!! awesome stuff \m/ may be the top bars can spawn when the cube reached their position!? I don’t know, over all this is amazing , keep rockin \m/
Thank you !
Yes I’m planning to polish that overall spawn animation, I’m thinking about something more constructed/sequenced to have a nice building effect.
Update on the spawning part, i changed colors and kept the particle grid, and made “corners” to show some kind of box (made from capsule-aligned billboards).
I also kept the “grid floor” part and added some noise on the opacity to get this disco-holographic pattern.
Also added some “VHS distortion” on the partixel to add some perturbation/organic feel.
Little sunday update with some more polish on the first part of the sequence. I tried several ways to get a nice “wavy” effect, and this is what I came up with (kind of full grid+turbulence pattern).
Here is a close-up specific shot of the globe:
You can see me changing the resolution on the gif.
