flow field fluid

Nikolaus Gradwohl2016-12-05T04:50:27+01:00

For this animation I created a particle simulation with fluid particles emitted from an icosphere. The particles are emitted along the y-axis and hit a forcefield, with the flow parameter set to 0.1. I used the cubesurfer addon by pytoevil to create a mesh from the particles.

forcefield flow explode

Nikolaus Gradwohl2016-12-01T04:19:50+01:00

I used the blender explode modifier to move the vertices of an icosphere in a turbulence forcefield in blender. The particles that move the vertices are form the same icosphere that acts as the emitter of the particles. If you do that make sure the particle system is the first modifier in the stack and that "use modifier stack" in the particle settings is NOT ticked. Otherwise this leads to pretty wired behaviour and probably a blender crash.

The forcefield has an increased flow parameter as with all my flow experiments.

To make the shards look like 3D objects instead of thin paperlike triangles I used the solidify modifier to give them a little bit of depth.

forcefield flow vortex

Nikolaus Gradwohl2016-11-29T05:45:35+01:00

For this animation I combined a vortex forcefield and a turbulence force field. As with all my latest particle experiments I increased the flow parameter of the turbulence forcefield. The particles are emitted by the faces of an icosphere.

flow field mesh

Nikolaus Gradwohl2016-11-25T04:13:12+01:00

For this experiment I used the turbulence forcefield with the flow parameter set to 2.0 to influence a set of particles using an emission shader to make them glow. I also used the "Mesh from Particles" template of the animation node addon to create the network.

In the compositor I used a defocus node to create the depth of field effect and a very slight lens distortion to add the dispersion color distortion at the edges of the image.

forcefield flow particle trace

Nikolaus Gradwohl2016-11-24T03:38:59+01:00

I created another particle set that interacts with a turbulence force field with the flow parameter set. This time I used the bTrace addon to trace 500 particles and create the purple particle trails. The bTrace addon creates the curves by stepping through all frames, taking the particle position and adding a new vertex to the curve.

I copied the purple material to all curves by selecting them and selecting Ctrl-L and "Material"

forcefield flow animation

Nikolaus Gradwohl2016-11-23T07:43:40+01:00

For this animation I used a turbulence forcefield to influence a set of particles emitted by a plane. at the beginning of the animation the flow parameter of the forcefield is set to zero. I keyframed the flow parameter and increased it during the animation. In the end the flow parameter stays at 1 to prevent the particles from leaving.

flow field experiment

Nikolaus Gradwohl2016-11-22T04:45:47+01:00

I created another particle simulation in blender - the particles are influenced by a turbulence force field. The size parameter is set to 2 and I increased the flow to 1. When this parameter is set the particles start to rotate and behave like in an air current. The particles are emitted from an icosphere with subdivision level 2 and flat shading.

drift off

Nikolaus Gradwohl2016-11-21T04:47:30+01:00

another particle animation in blender - I created some particles that take off from a plane and drift off the screen at a random speed.

I added a fresnel input to blend between the diffuse- and the glossy-shader on the sphere material used by the particles and I lit the whole scene using a sun light to create the shadows on the floor plane.

particles in the wind

Nikolaus Gradwohl2016-11-18T05:09:29+01:00

I just noticed that the last time I posted a processing sketch was in july - which is a shame. So to all the processing fans among my readers who are eagerly waiting for another sketch - here is my newest processing sketch.

I created a particle fountain in the middle of the screen and added a little bit of noise to the velocity of each particle. The noise fields are influenced by the current velocity and to add a bit of movement to the noisefield I also add a factor based on the current framecount to the noise function. If a particle leaves the screen it gets deactivated and is then reactivated in the middle of the screen at a random time.

If you like it or have any questions feel free to leave a comment below.

many force fields

Nikolaus Gradwohl2016-11-16T05:54:14+01:00

I rendered a new particle simulation in blender today. For this animation I placed 64 forcefields in a grid using a particle system on a cube. I've set the particle system physics to none and the particle placement mode to Grid to spread the particles evenly on the volume. Then I chose an empty with a forcefield as the particle object and applied the system, to turn the forcefields into objects. Then deleted the cube and added an ico-sphere with a new particle system. These particles are emitted inside the grid of focefields and use no gravity or inital velocity all movements are generated by the forces the fields exert on the particles.

Initially I wanted to render the animation with BI to speed things up, but in the end cycles rednered the frames faster on my GPU than BI could render them, so I used a diffuse shader-node and a sun light to render the scene.
