After The God Particle...

Going on with some tests for the animation of an underwater scene, this time playing with particle system and forces in blender (with which I am not very familiar). 

The particle system I used to create this shoal of fish is set with a simple fish model (same as [Abstract aquarium](https://skfb.ly/6ypzL)) as render object. 

The fish particle system was set to a "**Boids**" physics, and tweaking parameters gave the unique fish a smooth movement. A **vortex force field** was then added to the scene to create the swirling motion on the particles. I also added a collision domain (as a cube) to make sure that no fish went outside of a specified volume, but it proved unnecessary...

I still have to figure out how to properly export keyframed animations to a fbx file, as the only file I managed to obtain was a 120MB one (for a < 100 tris fish model). A python script which has helped me is [here](https://blender.stackexchange.com/a/7142), but it does not pass the export phase very well...

Box Aquarium

As it appears to be a trend, a small WIP diorama ([Nice one here!](https://skfb.ly/6xvV6)) just to try out some lighting technique for an incoming model (not a WIP I hope).

The refractive "box" around the model is just eye-candy, what was really of interest to me was to get an idea about bubbles (spheres with an emissive material coupled with dithering transparency), sun rays (elongated planes with blending opacity and a light emission to them) and the ground lights (not done well here, but basically voronoi textures to simulate the effect of waves on the light, baked on the ground model).

The ground is a quick and ugly dyntopo sculpt done in blender, while the little fish are just a particle system set with a lowpoly mesh as render object.

A nice point to spend time on will be the ocean surface, to do with the appropriate modifier in blender, and a refractive/small-scale-roughness/foamy-at-the-edges material.

Plus, I should try to animate rays, bubbles and fish (as boids) to give it a living touch.

Abstract aquarium

Conceptual model of floating restaurant. concept inspired by the sea turtle. This design concept encompasses space for lounge/bar restaurant zones. in the center is a aquarium wall for visual focal point.

Made with Fusion 360. A toy car with double-acting 1-cylinder compressed air engine (like the steam locomotives have). Has steering, which even works. I call it "vapemobile" because of the remote shape).

Apart from these printed parts, you'll need some extra ones to assemble it:

* 623ZZ bearing (4x10mm, 3mm hole) (may poorly work without it)
* Piece of 1.75mm filament
* Rubber band
* Thin plastic bag
* 6mm silicon pipe (can be found in any aquarium shop)
* 4mm pipe from intravenous dropper (or any that you could pull onto the syringe end)
* Two 2ml syringes
* 8mm piece of 4mm PTFE tube (optional)
* Air balloon
* Bolts: M3x6 x8, M3x8 x8, M3x10 x3, M3x12 x5, M3x14, M3x25, M3x50
* M3 washers x10
* M3 nuts x30

3d Printable Pneumatic-Engined Toy Car

This is a 3D model (“Tumbleweed”) of a juvenile Kemps Ridley Sea Turtle (ID 132) (*Lepidochelys kempii*) that was initially rescued by the New England Aquarium in Massachusetts, and then photographed with the Beastcam technology with 30 Canon G16 cameras. The sea turtle was released soon after in the Southern United States in good condition. The 3D model was initially created through a photogrammetry scan using Capturing Reality.  We digitally scrubbed the ID tag on the shell.

Animator Robert Gutierrez used Blender to reconstruct the full sea turtle from these scans, as well as animate the movements. Jeanette Wyneken from Florida Atlantic University, and Connie Merigo from the New England Aquarium each provided feedback on the movements.

Model 52A - Kemps Ridley Sea Turtle (no ID)

Here is a 3D photogrammetric reconstruction of a young whale that came to rest at the bottom of the ocean near Davidson Sea Mount off of Monterey Bay, CA.  The species of this whale is still being determined, but it is speculated to be a young Grey or Humpback Whale, which are often predated upon by Killer Whales in the area.  The whale is approximately 4 to 5 meters in length and was found at a depth of over 3000m.
Researchers at the Monterey Bay National Marine Sanctuary and the [E/V Nautilus](http://nautiluslive.org/video/2019/10/17/baleen-whale-fall-becomes-deep-sea-banquet-davidson-seamount) happened upon this whale in 2019, while surveying the nearby octopus brooding grounds.  Several octopus and species of bone-eating worms, called Osedax, which appear as red fur on the tail section, can be seen scavenging the whale. 

This model was reconstructed by a team at the Monterey Bay Aquarium Research Institute using approximately 600 still frames from video taken by ROV Hercules and the E/V Nautilus crew.

Whale Fall at the Davidson Octopus Gardens

The orange clownfish is widely known as a popular aquarium fish. Like other clownfishes, it often lives in association with sea anemones. A percula is associated specifically with Heteractis magnifica and Stichodactyla gigantea, and as larva use chemical cues released from the anemones to identify and locate the appropriate host species to use them for shelter and protection.

Model 51 - Kemps Ridley Sea Turtle (with ID)

Serrasalmus Compressus, prolly named after the shape of its body, though many piranhas share that, it also belongs to the carnivorous Serrasalmidae family of piranha fish and genus type is serrasalmus, known for having a strong bite and predatory behaviour. Wouldnt want to try and hand fed this one if it has not eaten for 3 days. In fact, when handeling another piranha species it bit a chunk out of my fingers when i was convinced i could just catch it with my aquarium net, first the net then my finger. And it was a cautionary bite, not to eat but to show it will not be fooled around with.

Serrasalmus Compressus

Northern Pike (Esox lucius), once held in my aquarium, easy to manage, would eat anything, but grew out of proportion too quick, and when the fish is longer than the aqaurium is wide, it is time for a bigger aquarium or for release. Top predator. This is not an equivalent of my pet pike

The Red Pacu Piranha (Piaractus Brachypomus), is not a real Piranha, despite belonging to the family  Serrasalmidae, this is a herbivor and actually a colorful one, harmless, often also called red-bellied Piranha or Red Piranha (Pygocentrus nattereri), its genus (Piaractus) tells us more factual information as well as the actual species which is Brachypomus, it can grown up to almost 90cm, and would not be recommended as a private aquarium fish unless you have spare space in Sea World

Red Pacu Piranha (Piaractus Brachypomus)

The Slender Piranha or Serrasalmus Elongatus or even Pike Piranha has lived 2,5 years in my aquarium, it had never ever tolerated any other thing or fish and would even attack my hand, Elong was the top predator, you will be missed, and a cousin of you has been digitalized too

Dragon Head Guppy Male. These guppies come in various bright colors, including shades of violet, red, orange, purple, yellow, and blue. They are swiftly swimmers, the species of guppy are very active in the aquarium and chase each other all day. You can prevent the strong dragon fish from harassing the weak ones by providing enough hiding space.

Three dragon guppies are recommended for a ten-gallon tank, though six to ten dragon fish can be kept in a twenty-gallon size tank.

Dragon Head Guppy Male

Im not making it less common but the Common Carp is a freshwater fish that can easily be kept in any aquarium, though it will become 75cm at least which would then require it to be the size of your living room, unless youre living in a deserted castle like me ofcourse, anyway, its a great gamefish too, my record is 92cm in length and 35 pounds in weight. Compared to variants with less scales, i.e. mirror carp, this one is much more resistant to diseases and parasites, but its looks are quite ehm common.

Common Carp (Cyprinus Carpio) Final

Zander (Sander lucioperca), perfect to be held in an aquarium, though once it reaches 22cm and eats 5 goldfish a day, better make sure you have a few of those ready and steady, which illustrates the only problem i had with my pet Glasoog, which therefore had to be released in the wild. The only other things to remember are that it highly depends on the right type of water, and will attack anything that enters the aquarium.

Zander (Sander lucioperca)

Bream (Abramis Brama), a very slimy fish, which most likely does not know when or why or how to eat, at least that is what i make up of it while it is taking hours to finally get hooked. The only fish you will not likely be keeping for very long in an aquarium, but who would want that anyway.

Bream (Abramis Brama)

The Pygopristis Denticulata is not as aggressive as most other piranhas but will eat anything. its family is serrasalmidae but its genus is pygopristis, from what i know its teeth are much smaller and finer than those of the more aggressive piranhas. That having said it is not a good idea to hand feed this one either, it is capable of some painful bites if cornered, which obviously would happen in the aquarium, unless its round ofcourse;) Your biggest challenge is obtaining one anyway

Denticulated Piranha (Pygopristis Denticulata)

Rudd (Scardinius Erythrophthalmus), in holland you will not encounter a more common fish than this one, i assume in England too, can also be kept in aquarium, even together with a pike, for a while at least;)

Rudd (Scardinius Erythrophthalmus)

Jarawee Lazuli Guppy Male. This guppy is named after the aquamarine stone of lapis lazuli. The bright blue head is similar to that of the Japanese blue guppy. It’s also known as the green algae guppy due to its coloring and stands out in any aquarium tank.

Beautiful plants for an aquarium like: Java Fern Narrow, Vallisneria, Staurogyne Repens and the Red Tiger Lotus
Actually these were at one time all in my own aquarium, which has had carp, eel, pike, walleye, koicarp, black piranha, slender pike, red bellied piranhas and a snakehead many years ago.
