The Technician

I used grid nodes for the 3d smoke sims, lots of fun possibility with them! (they also have many useful functions already implemented as nodes) but Im not sure they offer much performance improvement for a 2d sim

turned the compositor version into a smoke sim with dispersion

#blender #blender3d #b3d

I was using geonodes, with just a little shader stuff for some effects (sometimes doing the final steps in the shader lets me run the simulation on a less dense mesh).

the bump trick is pretty slick, but it doesn't work in the compositor, so I had to do that the hard way.

yeah, but I'm combining his method of caching frames with some of the fluid stuff I was already doing. Ive been looking to move all my 2d sim's into the compositor for performance

same basic effect, but running 4 times faster in the compositor

Thats wild! Love it

hmmmmm.....

Also the real one came with matching batteries (photo for ebay)

turn around!

3d of a real studio ghibli DVD player. these were introduced in 2002, tho Im not sure how long they made them. I like the kid sized 2nd remote with only the most important buttons.

thank you!! ^^

improved the boundary collisions and implemented pockets ^^

thanks! and yeah, its really crazy how much complexity these collisions add to the particle solver

made a basic particle sim with particle-to-particle collisions in #blender #geonodes
this version assumes a fixed density, but takes particle radius into account for the collision distance and mass.

I tried that first. It didnt work for the a 2 dimensional shape, only 1 dimentional waves.

it would be easy to get a better oscilloscope effect with geonodes tho, and with a simulation zone that could take a sound input.

thank you! yes, this can make different shapes, but it wont take a key-framed input, so no sound.

because there is no memory in the shader editor I generated the phosphor (which is basically motion blur) by offsetting the frame and recalculating, so the input has to be a math equation.

the nodes!

I got it working, but the phosopher took 2500 substeps per frame and made my gpu rev like a hot rodder pulling away from a stoplight

that flicker is physically accurate btw, and is very noticeable on the cheep scopes they make now

#oscilloscope #blender #blender3d #b3d

lol

you can make the beam like this, but not the phosphor, so it doesn't match the irl video

it'd be pretty easy in geonodes, because this is just x-y of a point controlled with two sin waves, + the phosphor effect keeping those points on screen to make lines, but replicating that in the shader editor requires a completely different approach

some discussion of Lissajous figures reminded me of this video I took of my oscilloscope (when I was supposed to be working lol)

I assume it has something to do with how blender interprets the node tree, there's some more complex stuff going on under the hood for error checking, anti-crash, ect, so I maybe it thinks this will cause an error. I think the real problems all give warnings now tho

huh, Ive never noticed that before, it might be a bug, but it works if you set it up like this. Ao can control the strength of the normal node.
