virtual const csVector4& iLightFactory::GetAttenuationConstants

(

)

const [pure virtual]

Get attenuation constants.

See also:

csLightAttenuationMode

virtual csLightAttenuationMode iLightFactory::GetAttenuationMode

(

)

const [pure virtual]

Return current attenuation mode.

csLightAttenuationMode

virtual const csColor& iLightFactory::GetColor

(

)

const [pure virtual]

Get the diffuse color of this light.

virtual float iLightFactory::GetCutoffDistance

(

)

const [pure virtual]

Get the the maximum distance at which the light is guaranteed to shine.

Can be seen as the distance at which we turn the light off. Used for culling and selection of meshes to light, but not for the lighting itself.

virtual float iLightFactory::GetDirectionalCutoffRadius

(

)

const [pure virtual]

Get radial cutoff distance for directional lights.

The directional light can be viewed as a cylinder with radius equal to DirectionalCutoffRadius and length CutoffDistance

virtual csFlags& iLightFactory::GetFlags

(

)

[pure virtual]

Get flags for this light.

Supported flags:

• CS_LIGHT_ACTIVEHALO

virtual const csColor& iLightFactory::GetSpecularColor

(

)

const [pure virtual]

Get the specular color of this light.

virtual void iLightFactory::GetSpotLightFalloff	(	float &	inner,
		float &	outer
	)			const [pure virtual]

Get spot light falloff angles.

Get in cosine of the angle.

virtual csLightType iLightFactory::GetType

(

)

const [pure virtual]

Get the light type of this light.

virtual iObject* iLightFactory::QueryObject

(

)

[pure virtual]

Get the iObject for this light factory.

virtual void iLightFactory::SetCutoffDistance

(

float

distance

)

[pure virtual]

Set the the maximum distance at which the light is guaranteed to shine.

virtual void iLightFactory::SetDirectionalCutoffRadius

(

float

radius

)

type

)

[pure virtual]

Set/Get the dynamic type of this light.

Supported types:
