Member Function Documentation

void FillHeightMap	(	int	_subSampling,
		unsigned int	_vertSize,
		const math::Vector3 &	_size,
		const math::Vector3 &	_scale,
		bool	_flipY,
		std::vector< float > &	_heights
	)

void FillHeightMap ( int  _subSampling, unsigned int  _vertSize, const ignition::math::Vector3d &  _size, const ignition::math::Vector3d &  _scale, bool  _flipY, std::vector< float > &  _heights  )

virtual

Create a lookup table of the terrain's height.

Parameters

[in]	_subsampling	Multiplier used to increase the resolution. Ex: A subsampling of 2 in a terrain of 129x129 means that the height vector will be 257 * 257.
[in]	_vertSize	Number of points per row.
[in]	_size	Real dimmensions of the terrain.
[in]	_scale	Vector3 used to scale the height.
[in]	_flipY	If true, it inverts the order in which the vector is filled.
[out]	_heights	Vector containing the terrain heights.

Implements HeightmapData.

std::string GetFilename

(

)

const

Get the full filename of the image.

Returns

The filename used to load the image

unsigned int GetHeight ( ) const

virtual

Get the terrain's height.

Returns

The terrain's height.

Implements HeightmapData.

float GetMaxElevation ( ) const

virtual

Get the maximum terrain's elevation.

Returns

The maximum terrain's elevation.

Implements HeightmapData.

unsigned int GetWidth ( ) const

virtual

Get the terrain's width.

Returns

The terrain's width.

Implements HeightmapData.

int Load

(

const std::string &

_filename = ""

)

Load an image file as a heightmap.

Parameters

[in]

_filename

the path to the image file.

Returns

True when the operation succeeds to open a file.
