A polar-plane-based method for natural illumination of plants and trees
We introduce an illumination method for outdoor scenes containing plants and trees. Our method supports multiresolution plant and tree models based on random L-systems. The method...

Natural Lighting of Vegetation based on Polar Planes
We present a lighting method for outdoor scenes with vegetation. The method is compatible with multiresolution trees generated using random L-systems. We include a sky dome model ...
