Constructor & Destructor Documentation

CloseDropsParticles::CloseDropsParticles (  SceneManager *  sceneMgr, SceneNode *  parentSyst, SceneNode *  parentCam )

constructor, taking in parameters : the SceneManager used in the scene the SceneNode to which the particle system should be attached the SceneNode to which the auxiliary camera (which we use to texture our drops) should be attached

CloseDropsParticles::~CloseDropsParticles (   )

Destructor

Member Function Documentation

void CloseDropsParticles::createLights (   )

function wich creates the lights (streetlights and bindings to light the drops)

void CloseDropsParticles::definePosTextureAndBackup (   )

function which creates the position texture and it's backup. should be called when initiaiting the rendering of the first frame (through frame listener)

RainLightManager * CloseDropsParticles::getLightManagerPtr (   )

function to retrieve a pointer to the rainLightManager associate with this CloseDropsParticles

void CloseDropsParticles::hidePositionBillboards (   )  [inline]

functions which hide the particle position billboards. billboards must be hidden when rendering the scene, and visible when updating the position texture

void CloseDropsParticles::makeControlOverlay (   )

control function, to check what the textures look like
