Occlusion Culling Algorithms

Di: Everly

PS. Also have in mind this: in some cases Three.js algorithms use the bounding box, in other cases it uses the bounding sphere. I think it might be a problem if you change the

In this paper, occlusion culling techniques that appeared in the last decade are reviewed. Occlusion culling techniques are responsible for reducing the polygons rendered by the graphics

Occlusion culling is a genre of algorithms for rapidly eliminating portions of three-dimensional geometry hidden behind other, visible objects prior to passing them to the rendering pipeline.

I would like to have some kind of occlusion culling. Here is an idea for an approach: API. Mesh objects have extra boolean fields: occluder, occludable Renderer has

• Occlusion culling algorithms compute a tight superset of the visible set so that the rest of the primitives can be discarded • This superset is called potentially visible set (PVS) • Occlusion

2.2 Culling Algorithms Culling algorithms accelerate rendering by quickly removing geometry that will not contribute to the final image. Back-face culling and view frustum culling are well known

In this paper, we present a novel hybrid occlusion culling method for large scale scenes. The basic idea is to use an iterative hierarchical Z-buffer occlusion culling algorithm to

The roots of occlusion culling in 3D graphics lie in hidden line and hidden surface determination algorithms. These algorithms are necessary to produce visually correct images

View frustum culling determines the primitives that lie outside of the user’s field of view. Occlusion culling determines the primitives that are occluded by other primitives. While back-facing and

它们的作用分别如下：backface culling用于剔除mesh背面的triangle，frustum culling用于剔除屏幕之外的物体，portal culling用于剔除不能通过portal看到的物体，

We present an OpenGL-assisted visibility culling algorithm to improve the rendering performance of large polygonal models. Using a combination of hierarchical model-space

We use a multi-pass algorithm, which decides the visibility based on low level of detail represen-tations of the geometric models. Our approach makes effi-cient use of hardware support for

In 3D computer graphics, hidden-surface determination (also known as shown-surface determination, hidden-surface removal (HSR), occlusion culling (OC) or visible-surface determination (VSD)) is the process of identifying what surfaces

This paper presents a scalable online occlusion culling algorithm, which significantly improves the previous raster occlusion culling using object-level bounding volume hierarchy.

Explore the existing methods for 3D occlusion culling, and learn how to use it during data prep stage to improve the performance of your 3D models and scenes.

Efficient occlusion culling in dynamic scenes is a very important topic to the game and real-time graphics community in order to accelerate rendering. We present a novel

Dynamic occlusion of course does not have to depend on occlu-sion queries, H. Batagelo and S. Wu present an output-sensitive occlusion culling algorithm for densely occluded dynamic

Recently, PVS-based occlusion culling algorithms for more general environments have been proposed. These algorithms follow the PVS principle in that they try to find a tight

从面给出的示例可以看出，这种用来避免低效率的算法可以带来速度上的补偿，具体可以将这些方法归类为遮挡裁剪算法（Occlusion Culling Algorithms），因为它们都试图裁剪掉被遮挡的部

occlusion culling algorithms that efficiently identify, then render, only thevisible portions of model a tightly-bounded superset thereof. In this paper, we exploit the presence of large occluders in

Unlike previous occlusion-culling algorithms, our technique can compute the occluded regions exactly and can thus discover when a polygon is hidden by multiple disconnected occluders.

Back in the day, an occlusion culling algorithm was the heart of a 3D game engine. You didn’t have a 3D game engine if you didn’t have an occlusion culling algorithm. Reply reply

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

Abstract Rendering of 3D scenes with a large number of objects is computationally intensive. Occlusion culling methods are used to improve rendering
