Nov 9, 1999 · The HV algorithm performs occlusion culling very efficiently because it only traverses visible octree nodes and their children, and it only renders the primitives in visible …

In this work, we present an efficient occlusion culling technique for 2D densely occluded scenes where both the viewpoint and objects move arbi-trarily. Our method operates on a regular grid …

This paper discusses options to realize 2D occlusion culling techniques using standard OpenGL functionalities, and introduces a novel 2D culling technique based on min-max mipmaps. We …

In this paper, we exploit the presence of large occluders in typical architectural or urban models to design a real-time occlusion culling algorithm. Our algorithm is based on several ideas.

In this paper we present an algorithm to extract simplified facades from complex building models, exploiting the fact that, in most cases, buildings have a 2.5D structure. Keywords : …

In this paper, we demonstrate its performance on a city model composed of 500,000 polygons and possessing varying depth complexity. We are able to cull an average of 55% of the …

We provide a broad overview of visibility problems and algorithms in computer graphics grouped by the proposed taxon-omy. The paper surveys visible surface algorithms, visibility culling …

In this paper, we present a new algorithm for the efficient occlusion culling of massive polygonal models. Given a viewpoint, our strategy is to carefully select a small set of polygons (called …

Two common types of occlusion culling are occlusion query and early-z rejection. This chapter examines the occlusion query and how to use it properly, including two examples proving how …
