This returns the resolution of the out-of-screen-fade-effect.

Returns
how many point samples are being used per axis
unsigned int orxonox::LensFlare::getPointCount ( float  dimension) const
private

This function generates point samples of the main burst billboard according to the fadeResolution and returns how many of them are in the view port.

Parameters
dimensionthe current dimension of the main billboard, we're always using square billboards
Returns
the absolute amount of point samples that are currently captured by the camera of the view port
float orxonox::LensFlare::getScale ( ) const
inline
bool orxonox::LensFlare::isFadeOnViewBorder ( ) const
inline

Determine whether the out-of-screen-fade-effect is on or off.

Returns
true if the effect is on, false if it is off
void orxonox::LensFlare::registerVariables ( void  )
private
void orxonox::LensFlare::setColour ( const ColourValue &  colour)
inline

This sets the base colour of the billboards.

Parameters
colourVector3 containing r,g,b values
void orxonox::LensFlare::setFadeExponent ( float  exponent)
inline

This sets the exponent of the fade-out function.

Parameters
exponenthow strong should the fade-out effect be
void orxonox::LensFlare::setFadeOnViewBorder ( bool  fadeOnViewBorder)
inline

Turn the out-of-screen-fade-effect on or off.

Parameters
fadeOnViewBordertrue to turn the effect on, false to turn it off
void orxonox::LensFlare::setFadeResolution ( unsigned int  fadeResolution)
inline

This sets the resolution of the out-of-screen-fade-effect.

the higher the resolution, the smoother the transition, but it will also have a greater impact on the performance this happens with O(n^2) since it's a two dimensional operation.

Parameters
fadeResolutionhow many point samples should be used per axis

note: this will always be an odd number, so the center point is included in the samples

void orxonox::LensFlare::setScale ( float  scale)
inline
void orxonox::LensFlare::tick ( float  dt)
overridevirtual

Gets called every frame.

Parameters
dtThe time since the last frame in seconds

Reimplemented from orxonox::Tickable.

void orxonox::LensFlare::updateBillboardAlphas ( float  alpha)
private

This function updates the alpha values for all billboards except for the one used for Hardware Occlusion Querying.

Parameters
alphathe new alpha value all visible billboards should use
void orxonox::LensFlare::updateBillboardStates ( const Vector3 &  viewDirection,
float  dimension,
bool  lightIsVisible 
)
private

This function updates the states of all the billboards, i.e.

their positions, visibilty and dimensions

Parameters
viewDirectionnormalised vector pointing from the current camera to the point light center
dimensionthe current dimension of the main billboard, we're always using square billboards
lightIsVisibleis the (point-)light source currently visible
void orxonox::LensFlare::XMLPort ( Element &  xmlelement,
XMLPort::Mode  mode 
)
overridevirtual

XML loading and saving.

Parameters
xmlelementThe XML-element
modeThe mode defines the operation that is being executed: loading or saving the object (from or to XML respectively)

Reimplemented from orxonox::WorldEntity.

Member Data Documentation

std::vector<Billboard*> orxonox::LensFlare::billboards_
private

The visible billboards.

ColourValue orxonox::LensFlare::colour_
private

this stores the base colour of the light

float orxonox::LensFlare::fadeExponent_
private

this determines how fast the flare fades away as it gets obstructed

bool orxonox::LensFlare::fadeOnViewBorder_
private

should the effect fade out on the border of the view?

unsigned int orxonox::LensFlare::fadeResolution_
private

how many points should be sampled per axis for the screen border fade. High number => smooth fade, but uses more processing power

std::vector<Lens> orxonox::LensFlare::lensConfiguration_
private

this stores the lensConfiguration

Billboard* orxonox::LensFlare::occlusionBillboard_
private

this is a transparent billboard used solely for the Hardware Occlusion Query

float orxonox::LensFlare::scale_
private

this factor is used to scale the billboard to the desired size
