Combined volume and surface rendering with global illumination caching

We present a combined volume and surface rendering technique with global illumination caching. Our approach uses volumetric path tracing to compute the global illumination volume and local shading models for rendering the isosurface. By joining both visualization approaches, we have enhanced the display and illumination of the surfaces while preserving physically realistic illumination of the participating media. To achieve real-time performance and avoid recomputing the image when the camera view changes, we compute the global illumination volume incrementally and defer the projection to a later step. We evaluated our technique by comparing different local shading models for isosurface rendering with the result of full volumetric path tracing and with the non-caching variant of our technique. Results show that the caching and non-caching variants perform comparably well, while the caching variant has the added benefit of being camera-view-independent. Additionally, we show that our approach emphasizes the surfaces within volumes better than volumetric path tracing.

“…plicity, flexibility, and ease of use. They can be acquired through a variety of techniques, including computer simulations, crystallography, electron microscopy (transmission tomography [KM86], cryo-electron tomography [KK09]), computed tomography [KSKV90], positron emission tomography [BMTV05], magnetic resonance imaging [Fos84], and 3D ultrasound [NE93,HZ17]. These techniques allow for the creation of highly detailed and accurate data, making them a rich source of volumes for a wide range of applications.…”

The Blocky Volume Package (BVP) format is a distributed, platform-independent and API-independent format for storing static and temporal volumetric data. It is designed for efficient transfer over a network by supporting sparse volumes, multiple resolutions, random access, and streaming, as well as providing a strict framework for supporting a wide palette of encoding formats. The BVP format achieves this by dividing a volume or a volume sequence into blocks that can be compressed and reused. The metadata for the blocks are stored in separate files so that a client has all the information required for loading and decoding the blocks before the actual transmission, decoding and rendering take place. This design allows for random access and parallel loading and has been specifically designed for efficient use on the web platform by adhering to the current living standards. In the paper, we compare the BVP format with some of the most often implemented volume storage formats, and show that the BVP format supports most major features of these formats while at the same time being easily implementable and extensible.

“…The micro-CT scanner uses a micro-focus X-ray tube with a focal diameter of several micrometers; notably, it can visualize the three-dimensional fine internal structures of materials with a significantly higher spatial resolution than that of CT scanners [ 10 ]. Moreover, micro-CT scanners have been widely employed for investigating the pathophysiology of smaller animals, such as mice and rats, and various reports have noted them to be a useful analysis tool [ 2 , 3 , 6 , 7 , 9 , 10 ]. Therefore, a micro-CT scanner can help in non-destructively and three-dimensionally analyzing the internal microstructures of pathological material before cutting.…”

In pathological diagnosis, the cutting position of pathological materials is subjectively determined by pathologists. This leads to a low cutting accuracy, which in turn may lead to incorrect diagnoses. In this study, we developed a system that supports the determination of the cutting position by visualizing and analyzing the internal structure of pathological material using micro-computed tomography (CT) before cutting. This system consists of a dedicated micro-CT and cutting support software. The micro-CT system has a fixture for fixing the target, enabling the scanning of easily deformable pathological materials. In the cutting support software, a function that interactively selects the extraction plane while displaying the volume rendering image and outputs a pseudo-histological image was implemented. Our results confirmed that the pseudo-histological image showed the fine structure inside the organ and that the latter image was highly consistent with the pathological image.
