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.

boid particles in a force field

Nikolaus Gradwohl2016-11-15T05:24:56+01:00

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+02:00

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.

animation node rotation

Nikolaus Gradwohl2016-07-19T06:56:24+02:00

For this animation I played with the rotation-wiggle node of the AN-addon in blender. To fade the wiggling rotation in and out I used an animation rotation node and a delay

animation node bubbles

Nikolaus Gradwohl2016-07-18T05:55:22+02:00

For this animation I used the AN-Addon vector wiggle node to animate a bunch of bubbles. The material is a combination of a transparent- and an emission-shader controlled by a fresnel-input node

animation nodes fold

Nikolaus Gradwohl2016-07-14T07:38:14+02:00

for this animation node experiment moved the vertices of a sphere using the wiggle node but made sure the node stayed on a spherical surface - which leads to a folding/crumbling effect

animation node vertex displace

Nikolaus Gradwohl2016-07-13T04:56:43+02:00

For this animation I used the animation node addon to displace each vertex of a icosphere using a vector wiggle node. The icosphere was rendered with freestyle enabled.
