Painting with polygons in BLender 2.8 - help needed

Question

I've been intrigued with paining with polygons effect - info below:

I have tried to recreate this in Blender 2.8. First I have created shader with displacement using texture offset:

After this I used linear interpolation and cycling over frame 0 and 1 with changing texture mapping rotation:

After that I tried rendering (In cycles) but it doesn't work. I am at loss what do next.

I have found one topic about this but it is from 2009 so not actual: https://blenderartists.org/t/painting-with-polygons/453991/7

I also found a guy who uploaded a working blend file, but it is for version 2.63 and I haven'T been able to recreate it. It can be found here: http://rylanwright.blogspot.com/2012/09/sharing-fun.html

Finally, here is my blend file: https://pasteall.org/blend/2706155074d9419da210ebd9950097e6

I would be very thankful if someone could help me to work this out, thanks in advance.

Answer 1

I managed to recreate painting with polygons by using the ideas from this paper. http://www.isaacbotkin.com/siggraph/

Here is my result:

To achieve the hand painted look by motion blur, i used the displacement modifier and did a variation of the "Strength" over time.

Also i did a little rotation of the monkey head during rendering a single frame.

To get the oszillation of the object during rendering, i defined this in the Dope Sheet so that the oszillation is performed multiple times during one frame.

Then i activated motion blur inside the Render Tab.

For a stronger representation of the blur effekt raise Diffuse value at Light Path settings.

At least i used a brush stroke Bump Map and a Gradient Texture node setup.

For the rendering i used a frame rate 25ps

and a render sampling rate of 600 and Pixel Filter 3
