Here's a visualization of global winds and precipitations on September 1st, 2019 (when [Hurricane Dorian](https://tinyurl.com/y3jewqqt) was hovering over the Bahamas, off the coast of Florida).

* Created in Python (using Matplotlib, NetCDF4, Scipy and Numpy modules)
* Public wind and precipitation data from the [NCEP/NCAR Reanalysis](https://tinyurl.com/y6mfqr6f)
* Wind particles colored according to speed (using Matplotlib "inferno" colormap)
* Rain particles scattered according to the precipitation rate

The seamless-loop effect was achieved by periodically spawning the particles at their initial location on a time range greater than the animation, and subsampling this time range before export. This effect was further enhanced by fading each particle's color to black at their birth and death, and using the "Additive" opacity in Sketchfab material settings to hide black points.

*PS: for Python enthusiasts, I've uploaded a [script to preview point cloud animations locally](https://tinyurl.com/yhyuuqev) !*

A collection of 282 (A.K.A more than you'll ever need) lowpoly people. Allright. Who cares. **Where is waldo?!**, that's the real question!

Automagically remeshing body scans to lowpoly assets (check out my growing collection of [free assets](https://skfb.ly/6yQSW)!), which can be used for archviz placeholders.

Each model has its origin located at its feet, so that placement in a scene is made easy. However, some refined scaling is probably needed as some children have become giants in the process...

Lowpoly People + Waldo

Yunnan Province, China, ~518 million years old.

<i>Vetulicola</i> had a large **body** with triangular **pouches** on either side and a segmented **tail** for swimming. The pouches may be gill slits opening into an internal body chamber, as found in modern tunicates, such as sea squirts and salps. It is thought that <i>Vetulicola</i> fed by drawing water in through the wide frontal opening to internally filter microscopic food particles suspended in water, with waste water expelled through the side pouches.

Vetulicola cuneata

Yunnan Province, China, ~518 million years old.

*Cotyledion* lived on the sea floor, using **tentacles** to feed on particles suspended in the water. Some individuals have been found attached to small fragment of trilobites. The overall body shape, presence of tentacles surrounding the mouth and U-shaped gut, are characters that unite *Cotyledion* with entoprocts – a modern group of animals that measure less than a centimetre across.

Cotyledion tylodes

A collection of reprocessed scanned animal skulls ([other free assets here](https://skfb.ly/6yQSW)), initally designed to be used as as game props, particles or for optimized renderings. 

**BUT**:  the method I used for remeshing and texture baking was not adapted in this case, and many normal inversions for instance have happened. Moreover, as these assets were batch-processed, I neglected some parts of the material, hence some black zones on the scans... 

You can of course still use them for your projects, but know that the quality on those baked models is not that good! Plus 1024px is too few for those complex objects...

Each model is made of 2500 triangles, and 1024 pixels albedo and normal maps.

The original scans were first remeshed with [mmgs](http://mmgtools.org), and decimated, UV unwrapped and baked in blender. Normal maps are ready to use for Unreal Engine, don't forget to flip their green channel in Unity!

All the original scans come from the great collection of UVic Libraries - @uviclib .

Educational project

Main study areas:

* 3d modelling of middle-complexity hardsurface object (bycicle), 
* texturing process (substance painter) and texture baking, 
* particles distribution (blender), 
* creating trees of a custom shape with prcedural workflow (built-in sappling addon) and creating planar foliage for tree (branches with leafs) 
* and overall environment setup for a small scene.

Main assets:

* Bycicle (4k x 4)- may be used as a background asset (a bit clunky geometry. Was reusing geometry from my old beginner's project)
* Bench, lantern, bin, package, tree (varies 4k-2k) - quality varies, can be used as a backround assets.
* Street elements, such as road, pavement and etc are hardly reusable..

Feedback is welcome :P

The house lost at sea

Wanted to make use of the long rendering time for commissioned work, so I decided to upload my recent castle build.

Minecraft 1.11 Map Download:

http://www.mediafire.com/file/l22h2a50ptt8yi9

*****

This build project was originally just a gradient palette test using the quartz, bone, mushroom stem, and diorite block. Then I decided to make a castle using that palette, with the angular roof style similar to the Minas Morgul of the LotR series. I've added animated gates with soundeffects using command blocks, and custom monsters that spawns randomly in the castle.

Unfortunately had to change the design before uploading because Mineways doesn't export armorstands, shulker boxes, and custom textured player heads.

*****

Built in Minecraft ver 1.11 using default texture. Map clean up with WorldEdit and MCEdit. Exported with Mineways (still getting misplaced blocks). Unwrapped uv in ZBrush. AO, light, and gradient map (for fake fog) baked in 3ds Max. Beacon light beam and snow particles added in 3ds Max.

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...

The Fish Particle

Yet another nice looking pointcloud ;)

Those latest models are just the results of me testing stuff to update and improve a small C++ particle simulations code I previously used to create [this model ("Need some space?")](https://sketchfab.com/3d-models/need-some-space-d6521362b37b48e3a82bce4911409303). 

I've made the code a bit more robust and easier to setup, tweak, and run... And I've just fixed some huge memory leaks and drastically improved its performance, Yipiii !

Liquid Splash 3

Given the recent scientific news and the fact that I'm on the "experimenting with volumetrics" path, I figured out that trying to reproduce space objects with simple force-driven particle simulation could be a fun exercise. Here are some first tests !

This object was made by moving 1000 particles around (rigid body rotation initial speed, one central repulsive force and two attractive ones), and "registering" their paths in an alpha voxels grid (225x225x225), which I finally mapped to textured planes for the volumetric effect.

A final central sphere was used with refraction parameters to create the center "black hole".

Might be resource intensive, sorry for that !

Not a Black Hole - 1

Visualization of global oceanic currents, averaged on the month of September 2019.

* Created in Python (using Matplotlib, NetCDF4, Scipy and Numpy modules)
* Public ocean data from the [NCEP Global Ocean Data Assimilation System (GODAS)](https://www.esrl.noaa.gov/psd/data/gridded/data.godas.html)
* Particles colored according to speed (using the “bone” colormap in Matplotlib)

If you are curious, [here](https://skfb.ly/6OGwB) is a similar model made by using similar tools and data, showing an animation of the winds and precipitation on September 1st, 2019.

Oceanic Currents

This is just an experiment with exporting a particle animation to Alembic format (.abc) from Blender.  I created the effect using similar steps as those shown in this tutorial (except I used a cube as the particle so it's lower poly, and I added randomness to the velocity, which I don't like in retrospect): https://youtu.be/k5WH5WY1Osc?si=Y1sfy87AwmzhI96m only up to the point where you start adding a material and adjusting render settings, since that is not necessary for export.

Initially I just selected the emitter and particle and exported them as Alembic with default export settings, and overall it worked remarkably well.  Sketchfab had no issue importing the animation.  Unfortunately though, without any adjustments, the animation's two stages (rising up into the air, then bursting) came out overlapped.  So I went looking for a way to fix that, and found a great Blender addon for baking particle effects by searching Gumroad for scaryplasmon CakeParticles.

In future tests I will remap the texture.
