Many variants exist that trade off accuracy and efficiency. In this work, we present an artifact-free, efficient, and easy-to-implement stencil shadow volume method. We compare our method to established stencil shadow volume techniques and show that it outperforms the alternatives.Computing methodologiesRenderingVisibilityA Practical and Efficient Approach for Correct Z-Pass Stencil Shadow Volumes10.2312/hpg.2019119545-49
