Detailed Description

Heightmap represents a shape defined by a 2D field, and is usually accessed through a Geometry.

Constructor & Destructor Documentation

◆ Heightmap()

sdf::v12::Heightmap::Heightmap ( )

Constructor.

Member Function Documentation

◆ AddBlend()

void sdf::v12::Heightmap::AddBlend ( const HeightmapBlend _blend)

Add a heightmap blend.

Parameters
[in]_blendBlend to add.

◆ AddTexture()

void sdf::v12::Heightmap::AddTexture ( const HeightmapTexture _texture)

Add a heightmap texture.

Parameters
[in]_textureTexture to add.

◆ BlendByIndex()

const HeightmapBlend* sdf::v12::Heightmap::BlendByIndex ( uint64_t  _index) const

Get a heightmap blend based on an index.

Parameters
[in]_indexIndex of the heightmap blend. The index should be in the range [0..BlendCount()).
Returns
Pointer to the heightmap blend. Nullptr if the index does not exist.
See also
uint64_t BlendCount() const

◆ BlendCount()

uint64_t sdf::v12::Heightmap::BlendCount ( ) const

Get the number of heightmap blends.

Returns
Number of heightmap blends contained in this Heightmap object.

◆ Element()

sdf::ElementPtr sdf::v12::Heightmap::Element ( ) const

Get a pointer to the SDF element that was used during load.

Returns
SDF element pointer. The value will be nullptr if Load has not been called.

◆ FilePath()

const std::string& sdf::v12::Heightmap::FilePath ( ) const

The path to the file where this element was loaded from.

Returns
Full path to the file on disk.

◆ Load()

Errors sdf::v12::Heightmap::Load ( ElementPtr  _sdf)

Load the heightmap geometry based on a element pointer.

This is not the usual entry point. Typical usage of the SDF DOM is through the Root object.

Parameters
[in]_sdfThe SDF Element pointer
Returns
Errors, which is a vector of Error objects. Each Error includes an error code and message. An empty vector indicates no error.

◆ Position()

ignition::math::Vector3d sdf::v12::Heightmap::Position ( ) const

Get the heightmap's position offset.

Returns
The heightmap's position offset.

◆ Sampling()

unsigned int sdf::v12::Heightmap::Sampling ( ) const

Get the heightmap's sampling per datum.

Returns
The heightmap's sampling.

◆ SetFilePath()

void sdf::v12::Heightmap::SetFilePath ( const std::string &  _filePath)

Set the path to the file where this element was loaded from.

\paramp[in] _filePath Full path to the file on disk.

◆ SetPosition()

void sdf::v12::Heightmap::SetPosition ( const ignition::math::Vector3d &  _position)

Set the heightmap's position offset.

Returns
The heightmap's position offset.

◆ SetSampling()

void sdf::v12::Heightmap::SetSampling ( unsigned int  _sampling)

Set the heightmap's sampling.

Defaults to 1.

Parameters
[in]_samplingThe heightmap's sampling per datum.

◆ SetSize()

void sdf::v12::Heightmap::SetSize ( const ignition::math::Vector3d &  _size)

Set the heightmap's scaling factor.

Defaults to 1x1x1.

Returns
The heightmap's size factor.

◆ SetUri()

void sdf::v12::Heightmap::SetUri ( const std::string &  _uri)

Set the URI to a grayscale image.

Parameters
[in]_uriThe URI of the heightmap.

◆ SetUseTerrainPaging()

void sdf::v12::Heightmap::SetUseTerrainPaging ( bool  _use)

Set whether the heightmap uses terrain paging.

Defaults to false.

Parameters
[in]_useTrue to use.

◆ Size()

ignition::math::Vector3d sdf::v12::Heightmap::Size ( ) const

Get the heightmap's scaling factor.

Returns
The heightmap's size.

◆ TextureByIndex()

const HeightmapTexture* sdf::v12::Heightmap::TextureByIndex ( uint64_t  _index) const

Get a heightmap texture based on an index.

Parameters
[in]_indexIndex of the heightmap texture. The index should be in the range [0..TextureCount()).
Returns
Pointer to the heightmap texture. Nullptr if the index does not exist.
See also
uint64_t TextureCount() const

◆ TextureCount()

uint64_t sdf::v12::Heightmap::TextureCount ( ) const

Get the number of heightmap textures.

Returns
Number of heightmap textures contained in this Heightmap object.

◆ ToElement()

sdf::ElementPtr sdf::v12::Heightmap::ToElement ( ) const

Create and return an SDF element filled with data from this heightmap.

Note that parameter passing functionality is not captured with this function.

Returns
SDF element pointer with updated heightmap values.

◆ Uri()

std::string sdf::v12::Heightmap::Uri ( ) const

Get the heightmap's URI.

Returns
The URI of the heightmap data.

◆ UseTerrainPaging()

bool sdf::v12::Heightmap::UseTerrainPaging ( ) const

Get whether the heightmap uses terrain paging.

Returns
True if the heightmap uses terrain paging.
