PolylightEffect Class Reference

A PolylightEffect can be used on a node to define a LightGroup for that node. A LightGroup contains PolylightNodes which are essentially nodes that add color to the polygons of a model based on distance. PolylightNode is a cheap way to get lighting effects specially for night scenes. More...

 Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams.

 Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...

◆ addLight()

const RenderEffect addLight ( const NodePath  newlight)

Add a PolylightNode object to this effect and return a new effect.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getContrib()

Returns CT_all or CT_proximal.

◆ getEffectCenter()

LPoint3 getEffectCenter ( )

Return the value of the _effect_center.

◆ getWeight()

float getWeight ( )

Get the weight value.

◆ hasLight()

bool hasLight ( const NodePath  light)

Returns true if the indicated light is listed in the PolylightEffect, false otherwise.

◆ make() [1/3]

static const RenderEffect make ( )
static

Constructs a new PolylightEffect object.

◆ make() [2/3]

static const RenderEffect make ( float  weight,
PolylightEffect::ContribType  contrib,
const LPoint3  effect_center 
)
static

Constructs a new PolylightEffect object.

◆ make() [3/3]

static const RenderEffect make ( float  weight,
PolylightEffect::ContribType  contrib,
const LPoint3  effect_center,
const PolylightEffect::LightGroup  lights 
)
static

Constructs a new PolylightEffect object.

◆ removeLight()

const RenderEffect removeLight ( const NodePath  newlight)

Remove a light from this effect. Return the new updated effect.

◆ setContrib()

const RenderEffect setContrib ( PolylightEffect::ContribType  c)

Set Contrib Type and return a new effect... the reason this couldnt be done through make was because that would return a new effect without the lightgroup which is static and cant be accessed Here, we just pass that to the make.

◆ setEffectCenter()

const RenderEffect setEffectCenter ( const LPoint3  ec)

Set weight and return a new effect... the reason this couldnt be done through make was because that would return a new effect without the lightgroup which is static and cant be accessed Here, we just pass that to the make.

◆ setWeight()

const RenderEffect setWeight ( float  w)

Set weight and return a new effect... the reason this couldnt be done through make was because that would return a new effect without the lightgroup which is static and cant be accessed Here, we just pass that to the make.
