Member Data Documentation

int VRS::AOLightingConfiguration::numSkyLightDirections

The sky light is simulated by light directions that are randomly distributed over the upper hemisphere.

A larger number of light directions increases preprocessing time but increases visual quality. 'numSkyLightDirections' may be 0, so that only directed sun light is visible.

VRS::Color VRS::AOLightingConfiguration::skyColor

int VRS::AOLightingConfiguration::numSunLightDirections

The sun light is simulated by light directions that are densely distributed around a given primary sun direction.

'numSunLightDirection' may be set to 0 to achieve typical Berlin weather. Larger values for 'numSunLightDirections' lead to smooth soft shadows, where small values, e.g., 1, lead to hard shaodws. The 'sunSize' is given in degrees of tolerance around the 'primarySunDirection'. The 'sunIntensityFactor' controls the brightness weighting between sun and sky.

VRS::Vector VRS::AOLightingConfiguration::primarySunDirection

double VRS::AOLightingConfiguration::sunSize

double VRS::AOLightingConfiguration::sunIntensityFactor

VRS::Color VRS::AOLightingConfiguration::sunColor

double VRS::AOLightingConfiguration::brightness

A brightness scaling factor that is applied to sky light as well as sun light.

SO<VRS::Iterator<VRS::Vector> > VRS::AOLightingConfiguration::lightDirections

Usually, the light directions are generated automatically based on the parameters described above.

Additionally, explicitly given light directions can be specified as well. If you want to use exclusively the explicit ones, set 'numSkyLightDirections' and 'numSunLightDirections' to 0. Note: Either both iterators must be NULL or they must both be defined and of equal size.
