Meteo Class

Members

void refresh ( ) #

Region * getRegion ( int64_t id ) #

Arguments

• int64_t id - Weather region identifier.

Return value

Vector < IG::Region * > getRegions ( ) #

void removeRegion ( int64_t id ) #

Arguments

• int64_t id - Identifier of the weather region/layer to be removed.

void clearRegions ( ) #

vec3 getMeanWindSpeed ( const dvec3 & world_pos ) #

Arguments

• const dvec3 & world_pos - Geographic coordinates of a point (lat, lon, alt), for which an average wind speed and direction are to be calculated.

Return value

void setWindSpeed ( const vec3 & wind_speed ) #

Arguments

• const vec3 & wind_speed - Vector defining wind speed in all directions, in meters per second.

void setVisibilityDistance ( float visibility_distance ) #

Arguments

• float visibility_distance - Global visibility range, in meters.

void setMaxPrecipitationAltitude ( double max_precipitation_altitude ) #

Arguments

• double max_precipitation_altitude - Upper height limit for precipitation, in meters.

double getMaxPrecipitationAltitude ( ) #

Return value

double getLowerCloudAltitude ( ) #

Return value

void setCloudsOptimization ( int enable ) #

Arguments

• int enable - 1 to enable simplified rendering for clouds; 0 - to disable it.

void setVisibilityTransitionTime ( float time ) #

Arguments

• float time - Time, in seconds, for gradual change of visibility range.

void setPrecipitationsTransitionTime ( float time ) #

Arguments

• float time - Time, in seconds, for gradual change of precipitation.

void setCloudTransitionTime ( float time ) #

Arguments

• float time - Time, in seconds, for gradual change of cloudiness.

void addCallbackMeteoChanged ( void * subscriber, Unigine::CallbackBase * callback ) #

/// callback function to be called when weather conditions change
void SomeClass::my_weather_callback()
{
	// setting orientation of the vane downwind
	vec3 wind_direction = ig_manager->getMeteo()->getMeanWindSpeed(vane_node->getWorldPosition());
	vane_node->setWorldDirection(wind_direction, vec3_up);
}

// ...
// somewhere in code
void SomeClass::init()
{
	// adding "my_weather_callback" to be called on changing weather conditions
	ig_manager->getMeteo()->addCallbackMeteoChanged(this, Unigine::MakeCallback(this, &SomeClass::my_weather_callback );
}

Arguments

• void * subscriber - Callback subscriber ID. This ID can be used to remove this callback when necessary.
• Unigine::CallbackBase * callback - Callback pointer.

void removeCallbackMeteoChanged ( void * subscriber ) #

Arguments

• void * subscriber - Callback subscriber ID specified when adding it.
