FFTCanvas is a simple, interactive 2D Fast Fourier Transform (FFT) visualizer built for the web. It's designed to help users intuitively explore how 2D frequency domain works, by drawing directly on a canvas and instantly seeing the FFT result.
- ✏️ Draw or upload images onto a 2D canvas
- ⚡ Instantly see the 2D FFT result
- 🔁 Switch between spatial and frequency domains
- 🌗 Optional real/imaginary or magnitude/phase visualizations
- 🧪 Great for learning, teaching, and experimenting
