Detailed Description

Base class for modifiers to the procedurally generated terrain.

Anything that modifies the terrain implements this interface.

Member Function Documentation

◆ apply()

virtual void Mercator::TerrainMod::apply	(	float &	point,
		int	x,
		int	y
	)		const

pure virtual

Apply this modifier on a terrain segment.

The segment is at x,y in local coordinates. Output is placed into point.

Implemented in Mercator::CraterTerrainMod< Shape >, Mercator::SlopeTerrainMod< Shape >, Mercator::AdjustTerrainMod< Shape >, and Mercator::LevelTerrainMod< Shape >.

Referenced by Mercator::Segment::applyMod().

◆ m_function

effector_func Mercator::TerrainMod::m_function

protected

Function used to apply this mod to existing points.

This makes the basic mods much more powerful without the need for extra classes. It completely obsoletes AdjustTerrainMod, which is now the same as LevelTerrainMod with this function changed from set() to sum()

Referenced by setFunction().
