Overview
Domain warping modifies the coordinates passed into a noise or texture function, usually by adding offsets sampled from another field. The result bends otherwise regular patterns into more organic structures.

When to Use
- Use when base noise looks too regular or axis-aligned.
- Use when repeatable distortion can be controlled by seed, scale, and amplitude.
When Not to Use
- Avoid when exact spatial alignment or monotonic coordinates are required.
- Avoid with warp amplitudes that fold or destroy important structure.
What It Does
- Samples a warp field
- Offsets coordinates before evaluating the main pattern
- Produces distorted procedural texture or terrain structure
Use Cases
- Organic terrain and texture generation
- Breaking grid-aligned noise artifacts
- Layered procedural material patterns
Inputs
- Base coordinates
- Warp noise
- Main noise function
Outputs
- Warped noise value or texture
Key Formulas (1)
Warped sample
value = noise(point + warpstrength · noisevector(point))
value = noise(point + warp_strength * noise_vector(point))Offsets lookup coordinates with another noise field.
Pseudocode
- 1.For each output coordinate
- 2.Sample a warp field to get an offset vector
- 3.Scale the offset by the warp amplitude
- 4.Add the offset to the original coordinate
- 5.Sample the base pattern at the warped coordinate
Canonical Example
- Input
- base noise at coordinate (x, y) and warp noise that returns offset (0.3, -0.1)
- Output
- base noise sampled at (x + 0.3, y - 0.1)
- Explanation
- The offset bends the coordinate domain before the final pattern is evaluated.
Implementation Notes
- Keep warp frequency, amplitude, and base noise frequency separately configurable.
- Test with grayscale previews before using the warped field in terrain or materials.
- Clamp or validate sampled coordinates when the downstream function has bounded input.
Common Pitfalls
- Warp amplitude that is too high can smear features beyond recognition.
- Using the same frequency for warp and base noise can create repetitive artifacts.
- Unrecorded seeds and parameters make visual bugs hard to reproduce.

warped-noiseNotes
Domain warping changes where a pattern is sampled; it does not change the base noise function itself.
