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 :-)

for this animation I animated the drawing of the circular grease pencil strokes themselves

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

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

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.

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

I started playing with generated textures in the shader node editor of blender. For this animation I used two sine nodes to calculate the displacement texture and the factor for the color mix node from the uv coordinates of a torus. Then I used a noise texture node to distort the texture coordinates and animated the scale factor

a short processing sketch drawing raindrops on a surface maybe I turn this into an animated texture for a blender render

Since my Strawberry plant started blossoming recently, I played with my macro lenses

for this animation I used two wave texture objects with different scales as the displacement texture
