Detailed Description

Class CLightEnv: description of a lighting environment - contains all the necessary parameters for representation of the lighting within a scenario.

Constructor & Destructor Documentation

CLightEnv()

CLightEnv::CLightEnv

(

Member Function Documentation

CalculateSunDirection()

void CLightEnv::CalculateSunDirection ( )

private

EvaluateUnitScaled()

RGBColor CLightEnv::EvaluateUnitScaled ( const CVector3D &  normal ) const

inline

Calculate brightness of a point of a unit with the given normal vector, for rendering with CPU lighting.

The resulting color contains both ambient and diffuse light. To cope with sun overbrightness, the color is scaled by 0.5.

Parameters

normal

normal vector (must have length 1)

GetElevation()

float CLightEnv::GetElevation ( ) const

inline

GetRotation()

float CLightEnv::GetRotation ( ) const

inline

GetSunDir()

const CVector3D& CLightEnv::GetSunDir ( ) const

inline

operator!=()

bool CLightEnv::operator!= ( const CLightEnv &  o ) const

inline

operator==()

bool CLightEnv::operator== ( const CLightEnv &  o ) const

SetElevation()

void CLightEnv::SetElevation

Member Data Documentation

m_AmbientColor

RGBColor CLightEnv::m_AmbientColor

m_Bloom

float CLightEnv::m_Bloom

m_Brightness

float CLightEnv::m_Brightness

m_Contrast

float CLightEnv::m_Contrast

m_Elevation

float CLightEnv::m_Elevation

private

Height of sun above the horizon, in radians.

For example, an elevation of M_PI/2 means the sun is straight up.

m_FogColor

RGBColor CLightEnv::m_FogColor

m_FogFactor

float CLightEnv::m_FogFactor

m_FogMax

float CLightEnv::m_FogMax

m_Rotation

float CLightEnv::m_Rotation

private

Direction of sun on the compass, in radians.

For example, a rotation of zero means the sun is in the direction (0,0,-1) and a rotation of M_PI/2 means the sun is in the direction (1,0,0) (not taking elevation into account).

m_Saturation

float CLightEnv::m_Saturation

m_SunColor

RGBColor CLightEnv::m_SunColor

m_SunDir

CVector3D CLightEnv::m_SunDir

private

Vector corresponding to m_Elevation and m_Rotation.

Updated by CalculateSunDirection.
