ronin experiment 1

Nikolaus Gradwohl2019-07-16T14:52:36+00:00

I discovered the livecoding environment ronin a lisp based environment thats described as a mix of vim and photoshop by it's creators.

Its in a pretty early stage of development and there isn't much documentation yet other than a few examples, but I have played with it for a few hours and I'm pretty impressed by what came out already.

floating rectangles in processing

Nikolaus Gradwohl2019-07-14T11:13:43+00:00

I created some floating rectangles in processing, that change their position and size and morph between the current and the new state

grease pencil experiment 4 - depth of field

Nikolaus Gradwohl2019-07-13T10:01:15+00:00

While experimenting with grease pencil animation scripted in python, i recognized that the grease pencil shapes also affect the depth map - so they can be used to change the DoF using the defocus node in the compositor. I was really pleasantly surprised - this opens a whole lot of new possibilities :-)

grease pencil experiment 2 - freestyle

Nikolaus Gradwohl2019-07-11T05:16:41+00:00

for this animation i used a python scripted grease pencil animation similar to that in my blogpost from yesterday and added a proper blender 3D Object. I rendered the animation with eevee and freestyle

scripted grease pencil animation experiment 1

Nikolaus Gradwohl2019-07-10T05:09:18+00:00

i recently read an article by Alex Martinelli about scripting the grease pencil objects in blender 2.8 (available here) and had to try this myself. I haven't used the grease pencil system in blender much so far, but now that I can use it to script in 3D I will definitly do more experiments with it.

the source code is heavily based on the examples of Alex, only the two nested loops are my code

corral structures from particle collisions

Nikolaus Gradwohl2019-07-09T06:53:47+00:00

I wrote a processing sketch that creates 2D corral like structures, by throwing a group of particles at a center location and making them stick whenever they hit another already sticked particle


the sketch starts by initializing a sticky particle at the seed location and then placing all other particles at random locations with their direction vector pointing to the seed particle

then each particle moves in the direction of the center and if it hits an already sticky particle it gets sticky as well. When two nonsticky particles collide, they get shifted around a to a random position to prevent them creating endless loops.

generative sine displacement texture in blender

Nikolaus Gradwohl2019-07-08T04:18:42+00:00

the texture in this animation was created in the shader editor by calculating the color value based on uv coordinates using math nodes
