bg-generation-domain-warping

Command line that generate "beautiful" image based on noise generation. The idea is inspired by this blog post

• Github : https://github.com/edmBernard/bg-generation-domain-warping

Usage

Single image

zig build --release=fast run -- <filename_without_ext> <width> <height> <variant>

This generates a JPEG image. variant is 1, 2, or 3.

Video

Raw RGB frames are written to stdout, pipe them to ffmpeg to encode a video:

zig build --release=fast run -- video <width> <height> <variant> <fps> <total_frames> | \
  ffmpeg -f rawvideo -pixel_format rgb24 -video_size <width>x<height> \
  -framerate <fps> -i - -c:v libx264 -pix_fmt yuv420p output.mp4

For example, a 10-second video at 30fps:

zig build --release=fast run -- video 1920 1080 1 30 300 | \
  ffmpeg -f rawvideo -pixel_format rgb24 -video_size 1920x1080 \
  -framerate 30 -i - -c:v libx264 -pix_fmt yuv420p output.mp4

Dependencies

We use :

• Zig : 0.15.2
• zpp : SIMD low level processing library.
• stb_image to save result as images.

Compilation

zig build

Disclaimer

It's a toy project. And I completly suck at Zig. So if you spot error, improvement comments are welcome.
