When to Use

Use when generating terrain needs random fault line.
Use when the input matches the assumptions behind terrain Generation.

When Not to Use

Avoid when the design needs strict authored control over every generated detail.
Avoid when a simpler algorithm gives the required result with less setup.

What It Does

Creates terrain by repeatedly raising one side of random fault lines
Uses random fault line and height displacement to guide the work.
Produces generated map, texture, layout, or pattern.

Key Formulas (1)

Fault update

height(p) += δ if side(line, p) > 0 else −δ

height(p) += delta if side(line, p) > 0 else -delta

Raises or lowers terrain depending on which side of the fault line a point lies.

Pseudocode

1.Prepare the inputs and state needed for Fault Formation Terrain.
2.Apply the random fault line step while the stopping condition has not been met.
3.Update intermediate state and discard invalid candidates.
4.Return generated map, texture, layout, or pattern.

Canonical Example

Input: Fault Formation Terrain input with a small representative case
Output: Generated map, texture, layout, or pattern
Explanation: Fault Formation Terrain applies random fault line to produce generated map, texture, layout, or pattern.

Implementation Notes

Keep the seed and parameters stored with generated output for reproducibility.
Keep the random fault line step separate enough to test independently.

Common Pitfalls

Small parameter changes can create large visual or structural differences.
Forgetting to check edge cases can make Fault Formation Terrain look correct on only ideal inputs.

Notes

Fault Formation Terrain should be used with the assumptions and tradeoffs of terrain Generation in mind.
