ACID EYE 360 VR - Psychedelic Deep Dream Fractal Trip 4K



http://www.fractalforums.com/index.php?action=gallery;sa=view;id=20410

360░ VR Deep Dream Fractal animation and slideshow in 4K - Mandelbulb 3D meets google Deep Dream

Use your Cardboard, Oculus Rift or other preferred virtual reality device to dive deep into this deep dreamed 3D fractal star and feel it all around you. Use clicked mouse, WASD-keys or navigation wheel when viewed on monitor or move your phone.

Visualizing a psychedelic experience to its full detail is really hard, but I hope this video can give an impression on these inner worlds.

Animation version

Slideshow version
The video compression at YouTube doesn't kill so much details, because this one is more static. So with the slideshow version you get a better impression of the original quality.

Animation version as flat 4K video
Just a flat, non-360░ version of the animation version. Here you can see the whole fractal deep dream world at one view.

Fractal Animation: rendered in 4K Ultra HD and 360 panorama mode with Mandelbulb 3D

About the google Deep Dream:
I always wanted to run a deep dream algorithm over one of my fractal animations to make it more trippy. But I thought: When you want to do it, then do it right!
So I didn't choose a normal animation as the fractal source but I used a 4K 360░ fractal as the source animation.
That wasn't easy and took a lot of experiments and programming in python.
Problems I had to solve:
- rendering 4K images via CPU is too slow - solution: use google deep dream with CUDA support so my GeForce GTX 970 could do the work much faster
- deep dreaming of 4K images wasn't possible because of memory problems (neural networks need a lot of RAM) - solution: for the final 4K dreaming do a lot of randomly selected 400x400 pixel dream squares
- keep also the fine 4K dream details stable during the animation so it doesn't flicker so much - solution: do some additional blending at the right time
- use various deep dream inception modes but blend them smoothly - solution: start the dreaming of the second animation already based on a fading sequence from the first animation and do some addition blending
- we have a 360░ video, so dream at left side should match to dream at right side - solution: copy a left stripe to the right and a right stripe to the left, dream and crop to original size
- we have a 360░ video, but you can't dream top and bottom correct - solution: blend top and bottom to black
- a fast changing scene is not so good for dreaming (flickering), so the original animation was too fast and I didn't want to render it again completly in 4K - solution: with a short python script create files with odd filenames (X000001.jpg, X000003.jpg, X00005.jpg). In Mandelbulb 3D: stretch animation by factor 2 and disable overwriting files. That way Mandelbulb renders only the even frames between the already rendered odd frames.
I will do a much more detailed tutorial and also release the python code later.

The deep dream itself has also fractal properties because you dream the image at various sizes (from small to big). That way the big structures can be also found as small structures.

Thank you Alex for the great warping, colorization, beat detection and the eternal light :-)
Because of the post processing (gave the files already in May to my friend) I couldn't add the "fractalforums.com Annual Fractal Art Contest 2017" directly in the video, but as always fractalforums.com is mentioned in the credits and the video description.

Enjoy your Deep Dream Fractal Trip
