Abstract
This paper discusses the method to display the surfaces that exhibit sparkling and depth effects. Sparkling effects are usually caused by the metallic flakes diffused in the paint or coating. The novelty of the approach is to explicitly model the sparkle normal vectors for rendering using an embedded device that allows us perceive depth effects in virtual reality like application. Light redirected by flakes to miscellaneous directions causes random twinkling particle effect. Since, each eye perceives light from different direction, there are two distinct perceived images with random particles for each eye. This effect causes the particles to be perceived within certain depth. We have created an application which allows us to render sparkling effect with arbitrary distributions of sparkles.
