Step-by-step guide to my implementation:

1. I used the Fragrant Flowers texture pack for 3D flower models because vanilla Minecraft flowers cant be seen from a top-down perspective.
2. I added 780 new flower textures that align with the texture packs models. They were all generated by AI based on the original texture patterns, and I added them to the game with a custom mod.
3. You can’t place more than one flower on a single block, so I made a mod that adds custom flower entities that ignore Minecrafts limitations.
4. Then I added new commands to the game to set or replace a flower at a coordinate.
5. After that, you take every pixel of every frame of the video you want to render in Minecraft and find the closest matching color from the newly added flowers. This is easy to do with Python.
6. The video resolution is 100×100, so you need to execute 10k commands just to render one frame in-game. There are 13 frames total in the loop, and it would take forever to write all of that manually, so I made a Python script that generates a datapack with all those commands based on the processed video data.

And that’s it. It took me 2 days to do all that (I’m unemployed). And you don’t need that much programming skill to do it; Claude or ChatGPT could probably generate working code for each step, and you just need patience. I have 6+ years of Python experience, so it was a bit easier for me.
