Detailed Description

Class storing the values in a vertex attribute array, instantiable from QML.

Values are stored as raw lists of floats, and must be interpretted by the consumer. For example, if this vertex attribute is actually a 2D float vector, the consumer must de-interleave the list into vectors.

TerrainMeshRenderer converts each of these into an AttributeArray, which are used to fill a Mesh.

Parameters

parent Parent object

Member Function Documentation

const QString& PolygonVertexAttributeArray::getName ( ) const

inline

Returns name.

const QList<float>& PolygonVertexAttributeArray::getValues ( ) const

inline

Returns values as a QList of floats.

QString PolygonVertexAttributeArray::getValuesAsBase64Binary ( ) const

Returns valuesAsBase64Binary.

QVariantList PolygonVertexAttributeArray::getValuesAsVariantList ( ) const

Returns values as a QVariantList.

void PolygonVertexAttributeArray::nameChanged ( )

signal

Emitted when name changes.

void PolygonVertexAttributeArray::setName ( const QString & value )

Sets name.

Parameters

value QString to set name to

void PolygonVertexAttributeArray::setValues ( const QList< float > & values )

Sets values from a QList of floats.

Parameters

values QList of float values to set values to

void PolygonVertexAttributeArray::setValuesFromBase64Binary ( const QString & base64Str )

Sets valuesAsBase64Binary.

Parameters

base64Str Base64 encoded array of floats

void PolygonVertexAttributeArray::setValuesFromVariantList ( const QVariantList & variants )

Parameters

variants QVariantList to interpret as a list of floats to set values to

void PolygonVertexAttributeArray::valuesChanged ( )

signal

Emitted when values changes.

Property Documentation

QString PolygonVertexAttributeArray::name

readwrite

Name of the attribute represented by this array, mapping it to the corresponding attribute in the Shader (in this case, TerrainShader) used for rendering.

QVariantList PolygonVertexAttributeArray::values

readwrite

List of floats contained in this array, as a QVariantList.

QString PolygonVertexAttributeArray::valuesAsBase64Binary

readwrite

List of floats contained in this array, encoded as a base64 string.

Data is encoded as follows:

float values are treated as a packed array of single precision IEEE floats
that array is then reinterpreted as a byte array
the byte array is in turn encoded as base64

Decoding reverses the process.

Note: This property is used for initialization (i.e. level load) efficiency. values can also be used, but it requires excessive QVariant creation and copying, as well as significantly more text processing.
