Abstract

Whenever approximate 3D geometry is projectively texture-mapped from
dierent directions simultaneously, annoyingly visible aliasing artifacts are
the result. To prevent such ghosting in projective texturing and image-based
rendering, we propose two dierent GPU-based rendering strategies: ltered
blending and
oating textures. Either approach is able to cope with impre-
cise 3D geometry as well as inexact camera calibration. Ghosting artifacts
are eectively eliminated at real-time rendering frame rates on standard
graphics hardware. With the proposed rendering techniques, better-quality
rendering results are obtained from fewer images, coarser 3D geometry, and
less accurately calibrated images.
