Abstract
Virtual reality (VR) is applied to the animation of shadow change as effected by light condition in plant factory. To study VR, we used work station which have a three-dimensional graphic system and three functions of shading, rendering and animation. Shading function was to add shade of structure, rendering function was to display shading object, animation function was to show moving object made by rendering.
We made three types of animation. First is the view of plant factory using the rendering function, second is the animation of movement of view point using animation function, third is the animation of moving shadow based on the sun and artificial light. We showed the animation of three structures based on VR. It took 48 hours to make the animation of 200 frames.
