Real-Time Shadow Rendering Using Projective Texture

Abstract

Shadow rendering is a complicated count in the GPU (Graphic Process Unit), it can simply and vivid render the model’s shadow in the scene, it will improve on the scene realistic image and provide artistic placement for the user. This paper emphasizes on the shadow rendering in the scene, using Projection Texture Shadow to render the model’s shadow in the scene. Texture image be the model’s shadow has simply and vivid features to reduce the complexity of the shadow rendering. In addition, in order to enhance the realistic shadow, except shadows’ color rendering, soft shadow rendering, and consider the projected shadows in the multiple models and determine the model in the scene should be shadowed or not.
