When we set out to build Neural Canvas, we had one rule: the artist stays in control. AI is a collaborator, not a replacement.
## The Problem with Generative Art Tools
Most AI art tools work like vending machines. Put in a prompt, get out an image. No iteration. No intention. No craft.
We wanted something different — a tool where every parameter is exposed, every layer is manipulable, and the feedback loop is instantaneous.
## Architecture
The pipeline has three stages:
### 1. Perception
Neural networks analyze input — could be a sketch, a photo, a webcam feed, or pure noise. We run multiple models in parallel using Web Workers, each extracting different features: edges, color fields, texture patterns, semantic regions.
### 2. Composition
This is where the artist works. A node-based editor lets you wire perception outputs to visual parameters. Edge detection might drive line weight. Color analysis might control palette. Semantic segmentation might determine layering.
Every connection is a creative decision. The same input, wired differently, produces completely different art.
### 3. Rendering
Custom GLSL shaders render the final output at 60fps. We use WebGPU where available, falling back to WebGL 2.0. The rendering pipeline supports multiple blend modes, post-processing effects, and resolution-independent output.
## The Secret: Feedback Loops
The real magic is that the output can feed back into the input. The camera sees the screen. The screen sees the camera. A feedback loop emerges — and the art begins to evolve on its own.
The artist's job becomes curation. Steering. Guiding something that's alive.
## Performance
Getting this to run at 60fps in a browser was the hardest engineering challenge we've faced. Key optimizations:
- **Tiled inference**: Neural networks process the image in tiles, spreading computation across frames
- **Shared array buffers**: Zero-copy data transfer between Web Workers and the main thread
- **Adaptive quality**: The system monitors frame times and adjusts model complexity in real-time
The result: gallery-quality generative art, running live, in your browser. No installs. No plugins. Just creativity.
