Code for creating Bad Apple animation in Blender.

Bad Apple on a 3D Cube

https://www.youtube.com/watch?v=Z-GpzGpXaLA

Always wanted to make bad apple myself, and it was quite a fun challenge. Also spent some time optimizing it with numba and i`m quite pleased with the results. This uses blender`s particle system and changes particles (cubes in this case) position according to positions of white pixels in a video.

Installation

This project uses python 3.9 and poetry.

1. Clone the repo

   git clone https://github.com/B0und/bad_apple_cube.git

2. Install dependencies with poetry

   poetry install

   or install manually with pip:

   pip install opencv-python,numba,numpy

Usage

1. Find and download Touhou_-_Bad_Apple.mp4. (I used 480x360 video, if your is different resolutions look at the scripts and change the constants)

2. Use python vid_to_frames.py to convert video to jpeg images.

3. Run python image_to_locations.py to create cube location files for blender to use.

4. Open blender and add a particle system to a default Cube.

5. Go to the scripting tab at the top, create a new script and paste the contents of blender_script.py, edit the project location, size constants and run it. Warning: this script will take ~3GB of memory, so don`t run it on potato pc.

6. Play the animation.
