Constructor & Destructor Documentation

TerrainInfo()

TerrainInfo::TerrainInfo

(

const Vec3 &

pos

)

Constructor to initialise terrain data at a given position.

Parameters

pos	The position to get the data from.

Member Function Documentation

getHoT()

float TerrainInfo::getHoT ( ) const

inline

Returns the height of the terrain.

getSurfaceInfo()

bool TerrainInfo::getSurfaceInfo	(	const Vec3 &	from,
		Vec3 *	position,
		const Material **	material
	)

Does a raycast upwards from the given position If the raycast indicated that the kart is 'under something' (i.e.

a specially marked terrain), to another raycast up to detect under whic mesh the kart is. This is using the special gfx effect mesh only. This is used e.g. to detect if a kart is under water, and then to get the proper position for water effects. Note that the TerrainInfo objects keeps track of the previous raycast position.

update() [1/3]

void TerrainInfo::update ( const btMatrix3x3 &  rotation, const Vec3 &  from  )

virtual

Update the terrain information based on the latest position.

Parameters

tran	The transform ov the kart
from	World coordinates from which to start the raycast.

update() [2/3]

void TerrainInfo::update ( const Vec3 &  from )

virtual

Update the terrain information based on the latest position.

Parameters

Position

from which to start the raycast from.

update() [3/3]

void TerrainInfo::update ( const Vec3 &  from, const Vec3 &  towards  )

virtual

Update the terrain information based on the latest position.

Parameters

Position

from which to start the rayast from.
