Realistic 3D Line Drawings from 3D Gaussian Splats
This post details a method for creating realistic 3D line drawings by augmenting the 3D Gaussian splatting process. The author combines the 3D Gaussian splatting technique by Kerbl et al. with a method for transforming photographs into informative line drawings by Chan et al. By swapping generated line drawings for original images and training for 21,000 iterations on an Nvidia RTX 4080S, the author achieves various styles (contour, anime, etc.) of 3D line drawing rendering. Experiments explore blending color information, splicing scenes, and image segmentation to enhance the effect and create diverse visual results. The results show that this method generates realistic and detailed 3D line drawings, but line drawing scenes are roughly double the size of their source scenes.
