Detailed Description

Info about the point being shaded and the lighting of the scene. Used for shaders that implement their own lighting.

Constructor & Destructor Documentation

LightingContext::LightingContext ( ) [inline]

LightingContext::LightingContext	(	I3DExRaytracer *	raytracer,
		const IllumSettings &	illum,
		const RendEnv &	rendEnv,
		const RTLevelInfo &	level,
		const uint32	seed
	)			`[inline]`

Member Function Documentation

void LightingContext::CalcReflectDir	(	const TVector3 &	rayDir,
		const TVector3 &	normal
	)			const `[inline]`

Computes the direction in which a ray reflects on a surface. The result is stored in fReflectDir

Parameters:

	rayDir	is the direction of the incomming ray
	normal	is the normal at the intersection point between ray and surface

const TMCColorRGBA& LightingContext::GetAmbientLight ( ) const [inline]

Returns the intensity of the ambient light in the scene

void LightingContext::Init	(	I3DExRaytracer *	raytracer,
		const IllumSettings &	illum,
		const RendEnv &	rendEnv,
		const RTLevelInfo &	level,
		const uint32	seed
	)			`[inline]`

Inits the lighting context

Member Data Documentation

boolean LightingContext::fCalculateTransparency

If fCalculateTransparency is true, the lighting model must calculate the alpha channel and the straight transparency (by opposition to refracted transparency)

FirstHitInfo* LightingContext::fFirstHitInfo

RayHit3D* LightingContext::fHit

const IllumSettings* LightingContext::fIllumSettings

lighting flags

const Ray3D* LightingContext::fIncomingRay

const RTLevelInfo* LightingContext::fLevel

LightingFlags LightingContext::fLightingFlags

TVector3 LightingContext::fNormal [mutable]

normal on current point after bump is applied (in global coord)

boolean LightingContext::fNormalFlipped

if the normal has been flipped
