Detailed Description

Encapsulates an image that will be interpreted as a heightmap.

Constructor & Destructor Documentation

gazebo::common::ImageHeightmap::ImageHeightmap ( )

Constructor.

Parameters
[in]_filenamethe path to the image

Member Function Documentation

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

Create a lookup table of the terrain's height.

Parameters
[in]_subsamplingMultiplier 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]_vertSizeNumber of points per row.
[in]_sizeReal dimmensions of the terrain.
[in]_scaleVector3 used to scale the height.
[in]_flipYIf true, it inverts the order in which the vector is filled.
[out]_heightsVector containing the terrain heights.

Implements gazebo::common::HeightmapData.

std::string gazebo::common::ImageHeightmap::GetFilename ( ) const

Get the full filename of the image.

Returns
The filename used to load the image
unsigned int gazebo::common::ImageHeightmap::GetHeight ( ) const
virtual

Get the terrain's height.

Returns
The terrain's height.

Implements gazebo::common::HeightmapData.

float gazebo::common::ImageHeightmap::GetMaxElevation ( ) const
virtual

Get the maximum terrain's elevation.

Returns
The maximum terrain's elevation.

Implements gazebo::common::HeightmapData.

unsigned int gazebo::common::ImageHeightmap::GetWidth ( ) const
virtual

Get the terrain's width.

Returns
The terrain's width.

Implements gazebo::common::HeightmapData.

int gazebo::common::ImageHeightmap::Load ( const std::string &  _filename = "")

Load an image file as a heightmap.

Parameters
[in]_filenamethe path to the image file.
Returns
True when the operation succeeds to open a file.
