Abstract
This paper attempts to create coloured semi-transparent shadow images that can be projected onto multiple screens simultaneously from different viewpoints. The inputs to this approach are a set of coloured shadow images and view angles, projection information and light configurations for the final projections. We propose a method to convert coloured semi-transparent shadow images to a 3D visual hull. A shadowpix type method is used to incorporate varying ratio RGB values for each voxel. This computes the desired image independently for each viewpoint from an arbitrary angle. An attenuation factor is used to curb the coloured shadow images beyond a certain distance. The end result is a continuous animated image that changes due to the rotated projection of the transparent visual hull.
