Detailed Description

Represents a cloud and all data and functionality associated with it.

Constructor & Destructor Documentation

Cloud::Cloud ( )

inline

Member Function Documentation

bool Cloud::AddToQueue ( Cloud *  cloudToUpdate )

static

Adds the cloud to the update queue.

Parameters

cloud

Cloud to be added to the update queue.

Returns

TRUE if the cloud has been added to the queue, FALSE if the cloud had already been in the queue.

void Cloud::CalculateBoundingBox

(

void

)

Computes the bounding box (bounding sphere, actually) of the cloud.

void Cloud::ComputeUpRightVectors

(

)

Deprecated:

Should be rewritten in OSG. Computes the new Up and Right vectors based on the curent view - used in the update of cloud particle rotations.

void Cloud::Delete

(

void

)

Deletes all the data associated with the cloud.

void Cloud::DestroyLightTexture ( void  )

static

Destroys the temporary texture used for the computation of lighting.

void Cloud::GenerateLightTexture ( void  )

static

Generates a temporary texture which is used for light computation. Based on the function used by Harris et al. (www.markmark.net/SkyWorks/)

void Cloud::InitCloudGeometry

(

osg::ref_ptr< osg::Geometry >

cloudGeometry

)

Initializes the geometry of the cloud, its vertices and color and texture coordinates.

Parameters

cloudGeometry

Geometry of the cloud which is used to create the cloud in it.

void Cloud::LightCloud

(

void

)

Deprecated:

Should be rewritten in OSG. Computes the lighting of the cloud.

void Cloud::RealizeQueue ( void  )

static

Realizes the cloud update queue.

void Cloud::RegularUpdate

(

)

Regular update of the cloud which is being called once per frame.

void Cloud::SetCamera ( const osg::Vec3f &  newCameraPosition, const osg::Vec3f &  newCameraView, const osg::Vec3f &  newCameraUp  )

static

Updates the camera data.

Parameters

newCameraPosition	Current position vector of the camera.
newCameraView	Current view vector of the camera.
newCameraUp	Current up vector of the camera.

static void Cloud::SetCloudParticleTexture ( osg::ref_ptr< osg::Texture2D >  newCloudParticleTexture )

void Cloud::SetLastCam ( osg::Vec3f  last_cam )

inline

static void Cloud::SetMaxCloudUpdates ( unsigned int  max )

inlinestatic

static void Cloud::SetSceneInfo ( const CloudSceneInfo &  info )

inlinestatic

static void Cloud::SetSunLight ( SunLight &  sun )

inlinestatic

static void Cloud::SetTranslateErrorTolerance ( float  tolerance )

inlinestatic

static void Cloud::SetViewMatrix ( const osg::Matrix &  newViewMatrix )

inlinestatic

void Cloud::UpdateCloud

(

)

Updates the vertices and color of the cloud.

void Cloud::UpdateCloudColor

(

)

Updates the color of the cloud.

void Cloud::UpdateCloudLotRocScale

(

)

Updates the vertices of the cloud.
