flow field mesh

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

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+00:00

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+00:00

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+00:00

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+00:00

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.

many force fields

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

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.

boid particles in a force field

Nikolaus Gradwohl2016-11-15T05:24:56+00:00

I rendered a new Particle simulation yesterday. For this animation I used a particle system with boid- or swarm particles that are influenced by a forcefield. I experimented with different values of the Flow parameter, and tried to find a sweet spot for the mass of the particles to prevent the particles from clumping together or dissolving immediately.

The particles use a simple white diffuse cycles material node. I set the world background to a grayish blue and added a slightly warmer light on the right side to create a little bit of contrast. I originally intended to add some volumetric light to make the scene look like under the sea - but that would have increased the render time dramatically so I sacrificed it to be able to render the animation over night.

DNA Nucleotides

I finally found the time to install and test blender 2.78. To test it I modeled the DNA nucleotides adenine, tyhmine, guanine and cytosine

animation node cube cluster

Nikolaus Gradwohl2016-07-27T07:16:36+00:00

For this experiment I morphed a cluster of random locations into the mesh of a cube using the animation node addon for blender. The mesh of the cube is then turned into a group of splines using the "find close vertices node" and the "Splines from Edges" node.
