Detailed Description

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

Member Function Documentation

void PolylightEffect::cull_callback ( CullTraverser trav,
CullTraverserData data,
CPT(TransformState)&  node_transform,
CPT(RenderState)&  node_state 
) const
virtual

If has_cull_callback() returns true, this function will be called during the cull traversal to perform any additional operations that should be performed at cull time.

This may include additional manipulation of render state or additional visible/invisible decisions, or any other arbitrary operation.

At the time this function is called, the current node's transform and state have not yet been applied to the net_transform and net_state. This callback may modify the node_transform and node_state to apply an effective change to the render state at this level.

Reimplemented from RenderEffect.

Definition at line 104 of file polylightEffect.cxx.

PolylightEffect::ContribType PolylightEffect::get_contrib ( ) const
inline

Returns CT_all or CT_proximal.

Definition at line 57 of file polylightEffect.I.

LPoint3 PolylightEffect::get_effect_center ( ) const
inline

Return the value of the _effect_center.

PN_stdfloat PolylightEffect::get_weight ( ) const
inline

Get the weight value.

Definition at line 47 of file polylightEffect.I.

bool PolylightEffect::has_cull_callback ( ) const
virtual

Should be overridden by derived classes to return true if cull_callback() has been defined.

Otherwise, returns false to indicate cull_callback() does not need to be called for this effect during the cull traversal.

Reimplemented from RenderEffect.

Definition at line 82 of file polylightEffect.cxx.

bool PolylightEffect::has_light ( const NodePath light) const

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