Implemented in NL3D::CLandscapeUser.

virtual void NL3D::ULandscape::setVegetableUpdateLightingFrequency (  float  freq  )  [pure virtual]

windFreq is the frequency for the animation (speed)
windPower is the power of the wind, and is a factor (0..1) of Bend
windBendMin is a value in (0..1) which indicate how much the vegetables are bended at minimum (for very powerfull wind)

show the landscape. visible by default.

Implemented in NL3D::CLandscapeUser.

virtual void NL3D::ULandscape::updateLightingAll (   )  [pure virtual]
 

update the lighting of ALL patch (slow method). NB: work even if UpdateLightingFrequency==0 Additionaly, vegetables are also ALL updated. WARNING!! If Scene Lighting is enabled (usual case), vegetable lighting setup take last Sun setup at UScene::render(). Hence, you should force the new lighting setup with ULandscape::setupVegetableLighting(), before calling updateLightingAll().
