this would depend on the projection of the map…

this would change depending on where you have your international date line… but assuming the date line is on the left edge of the screen and 90 degrees N is at the top edge of the screen and -90 is at the bottom edge, I think this would work:

lat = 47 ; // enter latitude value
lon = -122 ; // enter longitude value
y = linear( lat, -90, 90, 1080, 0 ) ;
x = linear( lon, -180, 180, 0, 1920 ) ;
[ x, y ]

i haven’t written an expression to load data from an external file, but it can be done. search this forum for terms like “load data csv”, then use that to fill the lat and lon values.

can you capture the sag playing another piece of software?

i capture the occasional htlm5 animation that way to bring it into ae. it will just be a footage element, but that’s usually all i need…

the branching is created by using the ‘aux system’ which can be set to allow the particles to emit particles.

however to get that those to branch again will be difficult, if not impossible….

the advanced lightning effect can create branch-like forms. set the glow settings to 0, enable decay main core and scrub the decay property yo see if that could pass as a growing tree branch. fiddle around with other settings like core radius, turbulence and forking to see if it might work….

sampleImage() has a time parameter: sampleImage(point, radius = [.5, .5], postEffect = true, t = time)

so you could p to this: p = L.sampleImage([i,h], [.1,.1], true, 5);

sample image would then only sample the frame at 5 seconds.

potentially… if your system gets low on ram, it will typically start caching to the main drive (i don’t believe that location can be changed in the OS). so, it’s possible that the combination of disk caching and reading/writing media could create a bottleneck, though SSDs are pretty darn fast…

plus you likely had a similar set up on your macbook…. so i’m not sure that’s the issue, at least not all of it.

pnot sure if your media setup might have been different on your macbook…. but having the media itself on a fast drive may help. put your 4k footage on a fast SSD with a fast bus/connection (like PCIe, USB3, Thnderbolt3, etc).

you may want to experiment with codecs too… a codec that compresses less will help reduce CPU load, but increase load on the drive that it is stored on (good for slower CPUs and/or fast SSDs) vs a codec that compresses more will have more load on CPU and less on the drive (good for fast CPUs and/or slow drives). so there’s a balance you need to find… though the conformed media cache is supposed to help wth that particular issue, so if that is on your fastest drive, then the may be as good as it is going to get.

the foam effect will allow you to use a ‘flow’ map — a grayscale image that the foam bubbles will follow. you can replace the ‘bubbles’ with a custom particle, so it might work for you… search for some tutorials on foam.

particular does allow the use of motion paths (under physics > air). those use the motion of a 3d light named ‘Motion Path 1’ (or Motion Path 2, etc). so you may be able to animate a light to follow the vein, then use that light as a motion path for the particles in a believable way.

on the original open, it looks like a simple mask or track matte layer with the pattern that is animated across the screen.

for the newer tv show version you might look at using card wipe on a solid and use the solid as a track matte. setting card wipe ‘rows’ to 1 will make vertical lines (or cards), setting the flip axis to ‘y’ will get the rotation needed and setting the back layer to ‘none’ will keep the solid from wiping back on.

make the solid larger than the comp to avoid seeing the top and bottom edges of the ‘cards’ as they rotate and also allow you to angle it to match the example.

try this on the scale property to flip the layer:
if ( transform.position.velocity[0] < 0 ) [ -value[0], value[1] ] else value
