simulo.SubTerrainConfig

Configuration for a sub-terrain type in rough terrain generation.

Sub-terrains are the building blocks of rough terrain. The terrain generator creates a grid of sub-terrains, where each cell is one of these configured types.

Attributes:

  • type — Sub-terrain type name. Supported types: - “flat”: Flat surface - “random_rough”: Random height variations - “pyramid_stairs”: Pyramid-shaped stairs (up and down) - “pyramid_stairs_inv”: Inverted pyramid stairs - “discrete_obstacles”: Discrete height obstacles - “wave”: Sinusoidal wave pattern - “hf_pyramid_slope”: Height-field pyramid slope - “hf_pyramid_slope_inv”: Inverted height-field pyramid slope
  • proportion — Proportion of terrain grid to use this type (0.0-1.0). Defaults to 1.0 — “use 100% of the grid for this single sub-terrain”. Every in-tree caller passes proportion= explicitly (Wave 0 audit verified), so the default-value change from the pre-Wave-B local default of 0.2 is safe.
  • params — Type-specific parameters (e.g., height, step_height, etc.)

Example:

# Random rough terrain with 0.02-0.1m height variations
rough = SubTerrainConfig(
    type="random_rough",
    proportion=0.2,
    params={"grid_height_range": (0.02, 0.1), "grid_width": 0.15}
)
