Detailed Description

Terrain class for 3D terrain.

The Terrain Object allows users to define a 3D textured and lit terrain based off of a heightmap texture. The class also provides various functions for interacting with the terrain.

Vect Terrain::GetSurfacePoint ( const Vect & pos )

Function that finds the surface point from a given world position.

This function takes in a vector position in world space and returns a similar vector position with an adjusted Y to the Terrain's surface. If the provided position is not above or below the Terrain then the returning vector will have a Y of zero.

Parameters

pos	Vect position in world space

Returns: Vect position of surface point

Matrix& Terrain::GetWorld ( )

Function that gets the world matrix of the Terrain.

Returns: reference to world Matrix.

void Terrain::SetLightColors ( const Vect & lightCol )

Function that sets the Light colors of the Terrain.

This function takes a single color vect and applies it to the ambient, diffuse, and specular light of the Terrain Object.

Parameters

lightCol Color vect for ambient, diffuse, and specular light

void Terrain::SetLightColors	(	const Vect &	amb,
		const Vect &	diff,
		const Vect &	spec
	)

Function that sets the Light colors of the Terrain.

This function takes in (and applies) a seperate color vect for the ambient, diffuse, and specular light of the Terrain Object.

Parameters

amb	Color vect for ambient light
diff	Color vect for diffuse light
spec	Color vect for specular light

void Terrain::SetTexture ( Texture * tex )

Function that sets the Terrain's texture.

Parameters

tex	A pointer to the Texture to be used

void Terrain::SetWorld ( const Matrix & mat )

Function that sets the world matrix of the Terrain.

Parameters

mat	A const Matrix reference for the world.
