Interactive Indirect Illumination Using Mipmap-based Ray Marching and Local Means Replaced Denoising
An interactive, one-bounce, and indirect illumination algorithm, which considers indirect visibility, is introduced. First, a ray marching algorithm (MRM), which is based on a 3D mipmap hierarchy structure generated by voxelizing the scene to accelerate the ray-voxel intersection, is used. Second, the indirect images are denoised by iterating an improved, edge-avoiding filtering with a local means replacement (LMR) method. The implementation demonstrates that our solutions can efficiently generate high-quality global illumination images even in a fully dynamic scene.
