Detailed Description

Compositor-based precipitation controller.

This class will add and control precipitation controllers to viewports.

Compositors clone the composing materials. This controller will register itself as a compositor listener and change the material in notifyMaterialSetup.

Member Function Documentation

PrecipitationType Caelum::PrecipitationController::getPresetType ( ) const

Get the preset type.

Will return PRECIPITATION_CUSTOM if you modify parameters manually after setPresetType.

void Caelum::PrecipitationController::setFallingDirection ( const Ogre::Vector3 & value )

inline

The basic direction for falling precipitation.

This property define the notion of a "falling down" direction. By default this is Vector3::NEGATIVE_UNIT_Y. You need to change this for a Z-up system.

References value.

void Caelum::PrecipitationController::setAutoDisableThreshold ( Real value )

inline

Automatically disable compositors when intensity is low.

A negative value always enable the compositor.

Note: : Ogre::CompositorInstance allocates/frees resources when enabling or disabling. That is expensive.

References value.

void Caelum::PrecipitationController::setCameraSpeedScale ( const Ogre::Vector3 & value )

inline

Automatically scale camera speed.

This is multiplied per-component with camera speed; manual or automatic. It's most useful for automatic camera speed to control how much of an effect moving the camera has on rain drop directions.

The components should probably be equal.

Default in Ogre::Vector3::UNIT_SCALE

References value.

void Caelum::PrecipitationController::update	(	Real	secondsSinceLastFrame,
		Ogre::ColourValue	colour
	)

Update the the precipitation controller.

Parameters

secondsSinceLastFrame Number of secods since the last frame.
