I made a volumetric material in cycles based on particle density. The particle set I used is influenced by a turbulence force field. I used a small ico-sphere as a particle object and added an emission shader. I noticed a pretty noticable offset between the particles and the volume material that changes over time - I'm not sure yet where that offset comes from, but I think it still looks pretty.

For this animation I have used an emission shader in a volumetric material for the first time. I added the shader on top of a volume scatter and a volume whatever shader and used a gradient curve to modify the density values for the emission shader a bit.

The input for the density function is a Point-Density Texture which is connected to a particle system.

The results aren' t quite as I expected them (which is kind of a recurring theme in my blender experiments :-) ) But I really like how it looks.

For this experiment I used a texture in blender and mapped it to the density value of a volumentric material

I experimented with some animated camera quaternoid rotations in blender

For this animation I used the "Network From Particles"-Template of the Animation-Node-Addon to add splines between clusters of particles

For this animation I combined a volumetric material and a particle system

To achieve the light effect I placed the particle system in a box with a that only uses a "Volume Scatter"-node in the material with a Density of 0.2

Then I used a Spot-Light with a linear light falloff, by plugging the "Linear" output of a "Light Falloff"-node into the strength input of the Emission-node.

For this animation I used a voumetric material on the world node

This animation was created with a goosberry testbuild of blender using the new point density node to create volumetric materials using particle systems in blender

you will need a gooseberry-testbuild to render the animation testbuilds of blender can be found here

the Toxiclibs are a very interesting collection of processing libraries. One of the libraries is called volumeutils and allows to use a volumetric space to model a 3D object.

I used it to generate a tentacle and export it as a stl file to make it printable on my 3D-printer.

In the setup method i define a volumetric space containing 100x100x100 voxel, a iso surface and a Triangle mesh (which is needed to display the object and export it later)

gfx = new ToxiclibsSupport(this);
VolumetricSpace volume = new VolumetricSpaceArray( new Vec3D(100,200,100), 100, 100, 100 );
IsoSurface surface = new ArrayIsoSurface( volume );
mesh = new TriangleMesh();
