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.

Vetulicola 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 Vetulicola 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.

The Sketchfab Model Inspector allows you to view the armature of any bones-driven animation  on Sketchfab. It also permits you to view the Bones weight, or the part of the model that is affected by a particular bone. To view the bones on the model above, just activate the Model Inspector (shortcut "I") and select "Bones". Alternately, you can press "6" on your number pad to view the bones, and press it again to view the bones weight. For more on this feature, head over to the [Sketchfab Help Center](https://help.sketchfab.com/hc/en-us/articles/115004862686-Model-Inspector#animation).

*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

Subsurface scattering (SSS) simulates the effect of light scattering inside an object. It is useful for translucent materials like skin, wax, and ice. Rotate the lights with ALT-drag (or three finger drag on mobile) to see this effect change in real-time. SSS is available on all plans, including Basic - [learn how to use it on our Help Center](https://help.sketchfab.com/hc/en-us/articles/204429595-Materials-PBR-#sss).

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...

[Camera Limits](https://help.sketchfab.com/hc/en-us/articles/115003399103-Camera-Limits) constrain the movement of the camera around a model or scene. In this Van Gogh Room, Camera Limits are used to hide the missing parts of the model to the viewer, making the experience more immersive. The [Model Inspector](https://help.sketchfab.com/hc/en-us/articles/115004862686-Inspector) will disable camera limits - click the icon in the bottom-right corner of the viewer, or press ‘I’ to try it out.

Refraction is the phenomenon that makes light bend when passing through different transparent materials due to the velocity of light changing in different media. It makes objects behind the refractive material look distorted. Refraction is useful for simulating glass, gemstones, and many other transparent materials. Real-time refraction is available on all plans, including Basic - [learn how to use it on our Help Center](https://support.fab.com/s/article/Transparency-Opacity).

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 !

Making progress on underwater scenes ( but still more to come :) ) !

[Original scan](https://skfb.ly/6suDz) from @ariosgeo, and inspiration from [Il Cristo degli Abissi](https://goo.gl/RU5PtJ), a submerged statue of Jesus in Italy.

**Modeling**:

* The scan was remeshed with [mmgs](http://mmgtools.org) from 500k verts to 7k, keeping the face and hands at a higher resolution.
* The ocean surface and ground were created with blender's ocean modifier.
* Light shafts are simply a randomized array of elongated planes.
* The fish is a lowpoly model ( a 30s model ).
* A particle system was created for fish instances, with force fields applied (boids physics, vortex, attraction force and collision on the statue)

**Texturing/lighting**:

* Mix of concrete and coral on the statue
* Sand on the ground
* Nothing on the sea surface
* Radial opacity for ground and surface
* Voronoi textures baked as emission on the statue and the ground, to simulate the light deformation through water
* Lots of color processing

Refraction is the phenomenon that makes light bend when passing through different transparent materials due to the velocity of light changing in different media. It makes objects behind the refractive material look distorted. Refraction is useful for simulating glass, water, gemstones, and many other transparent materials.

To see for yourself how refraction works, just rotate the model, paying attention to how the shell appears to distort beneath the egg white.

Free high-poly liquid splash mesh.
Had a recent project where I had to learn using X-Particles. these are the results of days of watching tutorials, simulations, & trial and error.
Enjoy.

Liquid Splash 2

A little scene tightly inspired (badly copied/recreated) from the animated video-clip of ["Bouche à lèvres"](https://youtu.be/OrvkJJc4yLc) (warning: contains nudity) by **Odezenne**, one of my favorite french bands.

The clip was directed by [Vladimir Mavounia-Kouka](https://www.vladimirmavouniakouka.com/), and gives a crude view of the fear and anticipation of fatherhood depicted in the song.

The woman in this model is from makehuman, and the assets were naively modeled in blender, then scattered with a simple particle system.
