(

const HeightmapBlend &

_blend

)

Add a heightmap blend.

Parameters

[in]

_blend

Blend to add.

AddTexture()

void sdf::v9::Heightmap::AddTexture

(

const HeightmapTexture &

_texture

)

Add a heightmap texture.

Parameters

[in]

_texture

Texture to add.

BlendByIndex()

const HeightmapBlend* sdf::v9::Heightmap::BlendByIndex

(

uint64_t

_index

)

const

Get a heightmap blend based on an index.

Parameters

[in]

_index

Index 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::v9::Heightmap::BlendCount

(

)

const

Get the number of heightmap blends.

Returns

Number of heightmap blends contained in this Heightmap object.

Element()

sdf::ElementPtr sdf::v9::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::v9::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::v9::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]

_sdf

The 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.

operator=() [1/2]

Heightmap& sdf::v9::Heightmap::operator=

(

Heightmap &&

_heightmap

)

Move assignment operator.

Parameters

[in]

_heightmap

Heightmap to move.

Returns

Reference to this.

operator=() [2/2]

Heightmap& sdf::v9::Heightmap::operator=

(

const Heightmap &

_heightmap

)

Copy Assignment operator.

Parameters

[in]

Sampling()

unsigned int sdf::v9::Heightmap::Sampling

(

)

const

Get the heightmap's sampling per datum.

Returns

The heightmap's sampling.

SetFilePath()

(

const std::string &

_filePath

)

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

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

SetPosition()

void sdf::v9::Heightmap::SetPosition

(

const ignition::math::Vector3d &

_position

)

Set the heightmap's position offset.

Returns

The heightmap's position offset.

SetSampling()

void sdf::v9::Heightmap::SetSampling

(

unsigned int

_sampling

)

Set the heightmap's sampling.

Defaults to 2.

Parameters

[in]

_sampling

The heightmap's sampling per datum.

SetSize()

void sdf::v9::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::v9::Heightmap::SetUri

(

const std::string &

_uri

)

Set the URI to a grayscale image.

Parameters

[in]

_uri

The URI of the heightmap.

SetUseTerrainPaging()

void sdf::v9::Heightmap::SetUseTerrainPaging

(

bool

_use

)

Set whether the heightmap uses terrain paging.

Defaults to false.

Parameters

[in]

_use

True to use.

Size()

ignition::math::Vector3d sdf::v9::Heightmap::Size

(

)

(

uint64_t

_index

)

const

Get a heightmap texture based on an index.

Parameters
