trapped light
For this animation I placed a lightsource inside a transparent object with an animated displacement texture. The lightsource is a simple sphere with a emmission shader.

For this animation I used an XYZ-Function from the Extra Objects addon to create a "Clifford Torus" and added an diplacement modifier and keyframed the turbulence factor of the magic texture to create the movement

For this animation I created a particlesystem on a ico-sphere mesh that emits exacly one particle per vertex. Then I used the animation node addon to move the vertices of the mesh along with the corresponding particle. The particles are influenced by a curly noisefield.

For this animation I used the latest beta of the animation nodes 2.0 addon, to create polygons form particles using the KVTree nodes

For this animation node experiment I copied instances of a hollow box and rotated them slightly using a loop

For this animation I used a dynamic paint canvas on a plane that emits hair particles based on a wet map. I used another particle system as the dynamic paint brush

For this animation I distributed instances of a box on instances of a bezier circle and delayed their appearance by animating their scale

For this animation I used the distance node from the animation nodes addon to change the height of the boxes based on their distance to an empty.

For this animation I used the animation nodes "distribute instances on spline"-Template and animated the instances using a math node and wiggle node. I rendered the animation using cycles and freestyle.

read more ...denoising blender animations with opencv and python
Nikos Priniotakis posted a teaser of a denoising script for blender animations a few months ago, that shows really impressive improvements on a noisy cycles animation (see his original tweet here) I sent some twitter messages back and forth with him and he sent me the links to the opencv denoise function he used for the demo. So I finaly found the time to wirte a short python script that uses pyopencv to denoise all the pictures in a folder and copies it to another folder.
The script I used to denoise my animation is here
import cv2
import os
import numpy as np
from matplotlib import pyplot as plt
files = os.listdir("metabubbles/")
for f in files:
if f.endswith('.png') and f.startswith('0'):
print f
img = cv2.imread("metabubbles/%s" %f);
dst = cv2.fastNlMeansDenoisingColored(img)
cv2.imwrite('res/%s' %f, dst);
The denoising process is no magical pixiedust that can be sprinkled on your noisy cycles-renders to fix everything but when used correcly it can improve preview renders a lot, but if the script is used on an image sequence that is too noisy it introduced a whole lot of new artifacts. I used the script on an amiation I rendered last year. Here is how the original video compares to the denoised version.
