Function clearUnwalkableTriangles

clearUnwalkableTriangles(
    inVertices: ArrayLike<number>,
    inIndices: ArrayLike<number>,
    inOutTriAreaIds: ArrayLike<number>,
    walkableSlopeAngle?: number,
): void
Clears (sets to NULL_AREA) triangles whose slope exceeds the walkable limit. Mirrors markWalkableTriangles but does the inverse operation.
Parameters
- inVertices: ArrayLike<number>
  Array of vertex coordinates [x0, y0, z0, ...]
- inIndices: ArrayLike<number>
  Array of triangle indices [i0, i1, i2, ...]
- inOutTriAreaIds: ArrayLike<number>
  In/out array of triangle area IDs (modified in place)
- walkableSlopeAngle: number = 45.0
  Maximum walkable slope angle in degrees (default: 45)
Returns void
- Defined in src/generate/input-triangle-mesh.ts:77
