Floating Textures
Comput. Graph. Forum(2008)
摘要
We present a novel multi-view, projective texture mapping technique. While previous multi-view texturing ap- proaches lead to blurring and ghosting artefacts if 3D geometry and/or cam era calibration are imprecise, we propose a texturing algorithm that warps ("floats") projected textures du ring run-time to preserve crisp, detailed texture appearance. Our GPU implementation achieves interactive to real-tim e frame rates. The method is very generally applicable and can be used in combination with many image-based rendering methods or projective texturing applications. By using Floating Textures in conjunction with, e.g., v isual hull rendering, light field ren- dering, or free-viewpoint video, improved rendering results are obtain ed from fewer input images, less accurately calibrated cameras, and coarser 3D geometry proxies.
