Title:
- View-Dependent Textured Splatting for Rendering Live Scenes

Abstract:
This sketch presents a novel approach for rendering low resolution point clouds with multiple high resolution textures–the type of data commonly generated by real-time vision systems. The low precision, noisy, and sometimes incomplete nature of such data sets is not suitable for existing point-based rendering techniques that are designed to work with high precision and high density point clouds.
Our new algorithm–View-dependent Textured Splatting (VDTS)– combines traditional splatting with a view-dependent texturing strategy to increase rendering quality of low resolution data sets with high resolution textures. VDTS requires no pre-processing, addresses texture visibility and anti-aliasing on the fly, and can be efficiently accelerated by commodity graphics hardware. Therefore it is well suited for real-time rendering of dynamic scenes online.
