LightSourceType
Light source types for 3D scenes.
@ Directional
Directional light source.
static QColor colorFromString(const QString &string)
Decodes a string into a color value.
static QString colorToString(const QColor &color)
Encodes a color into a string value.
bool operator==(const QgsDirectionalLightSettings &other)
QgsDirectionalLightSettings * clone() const override
Returns a copy of the light source.
float intensity() const
Returns intensity of the light.
QColor color() const
Returns color of the light.
QDomElement writeXml(QDomDocument &doc, const QgsReadWriteContext &context=QgsReadWriteContext()) const override
Writes the light source's configuration to a new DOM element and returns it.
QgsDirectionalLightSettings()=default
Construct a directional light with default values.
Qt3DCore::QEntity * createEntity(const Qgs3DMapSettings &map, Qt3DCore::QEntity *parent) const override
Creates an entity representing the light source.
void readXml(const QDomElement &elem, const QgsReadWriteContext &context=QgsReadWriteContext()) override
Reads configuration from a DOM element previously written using writeXml().
QgsVector3D direction() const
Returns the direction of the light in degrees.
Qgis::LightSourceType type() const override
Returns the light source type.
The class is used as a container of context for various read/write operations on other objects.
Class for storage of 3D vectors similar to QVector3D, with the difference that it uses double precisi...
double y() const
Returns Y coordinate.
double z() const
Returns Z coordinate.
double x() const
Returns X coordinate.
void set(double x, double y, double z)
Sets vector coordinates.
