The interior light environment in greenhouses affects the growth of crops. Researchers have extensively studied improvements in greenhouse light environments. In this article, computer technology was used based on light path tracing and the Monte ...

Light field displays represent yet another step in continually increasing pixel counts. Rendering realistic real-time 3D content for them with ray tracing-based methods is a major challenge even accounting for recent hardware acceleration features, as ...

Monte Carlo integration is an established method in simulating light transport. However, due to its stochastic nature, it requires copious amounts of samples to eliminate the estimation error, and variance reduction techniques such as ...

• A modified spatio-directional tree that captures the radiance field in a scene.

We propose a real-time hybrid rendering algorithm that off-loads computationally complex rendering of indirect lighting from mobile client devices to dedicated ray tracing hardware on the server with a hybrid real-time computer graphics rendering ...

Path tracing can generate realistic images based on virtual 3D scene models, but the images are prone to be noisy. To solve this problem, we developed a novel denoising algorithm framework. Firstly, according to the relative mean square error of ...

This study examines the physical features involved in navigating maps representing urban areas and more specifically when making decision to reach a defined location. A subject is presented a series of maps and is asked to draw the shortest path ...

We present a color mapping method that corresponds to intensity and considers the interaction of light among objects in a 3-dimensional scene. Previous methods that map color according to geometric specifications or a rendered result do not reproduce ...

Path tracing produces realistic results including global illumination using a unified simple rendering pipeline. Reducing the amount of noise to imperceptible levels without post-processing requires thousands of samples per pixel (spp), while currently ...

Recent interactive rendering approaches aim to efficiently produce images. However, time constraints deeply affect their output accuracy and realism (many light phenomena are poorly or not supported at all). To remedy this issue, in this paper, we ...

Debugging is difficult and costly. As a programmer looks for a bug, it would be helpful to see a complete trace of events leading to the point of failure. Unfortunately, full tracing is simply too slow to use after deployment, and may even be ...

Complete dynamic control flow is a fundamental kind of execution profile about program executions with a wide range of applications. Tracing the dynamic control flow of program executions for a brief period easily generates a trace consisting of ...

Software-defined networking brings extra complexity to debugging while enhancing network manageability. The competition between applications and subtle bugs in controllers or switches may cause inconformity between control plane logic and data plane ...

Noise removal for Monte Carlo global illumination rendering is a well known problem, and has seen significant attention from image-based filtering methods. However, many state of the art methods breakdown in the presence of high frequency features, ...

In this paper, we seek to eliminate the noise caused by caustic paths during progressive Monte Carlo path tracing. We employ a filtering strategy over path space, handling each subspace using specialized derivations of path tracing and progressive ...

In many applications, volumetric data sets are examined by displaying isosurfaces, surfaces where the data, or some function of the data, takes on a given value. Interactive applications typically use local lighting models to render such surfaces. This ...
