Member Function Documentation

void CloudsManager::Delete

(

void

)

Deletes the cloud manager and all clouds associated with it.

void CloudsManager::LoadAndInitiate

(

void

)

Initializes and generates (loads from files) all the clouds and attributes associated with them (also saves them afterwards to disk if necessary).

int CloudsManager::LoadFromFile

(

void

)

Loads previously saved cloud files from the disk into the manager's std::vector. Files are loaded sequentially in ascending order. If the loading process of one of any them fails, all the following files are not loaded.

Returns

0 if at least one cloud file was successfully loaded, false otherwise.

int CloudsManager::SaveToFile

(

void

)

Saves the clouds into filesystem, every cloud in a separate .txt file.

Returns

0 if everything went well and all files were saved to the disk, -1 otherwise.

void CloudsManager::SetUVCoords

(

bool

singleTexture = false

)

Set up the UV texture coordinates for all of the cloud particles.

Parameters

singleTexture

Indicates whether the cloud texture cotains a single texture which is displayed on every particle or four different textures for different values of alpha channel (optional, default = false)

void CloudsManager::Update	(	const osg::Vec3f &	cameraPosition,
		const osg::Vec3f &	cameraView,
		const osg::Vec3f &	cameraUp
	)

Updates the status of all of the clouds and launches the realization of the update of impostors from the priority queue.

Parameters

[in]	cameraPos	Position of the camera.
[in]	cameraView	Direction in which the camera is looking.
[in]	cameraUp	The 'Up' direction of the camera.
