Description:
The film shows changing lighting effects on three trees, with leaves fluttering in the breeze, as clouds obscure the sun. The moving shadows on the ground include the penumbra from the sun and the effects of illumination from the sky and clouds. They were computed from the point source shadows by an FFT-based convolution with a combined sun and sky brightness raster.
