NeMF: Inverse Volume Rendering with Neural Microflake Field
IEEE International Conference on Computer Vision, 2023Recovering the physical attributes of an object’s appearance from its images captured under an unknown illumination is challenging yet essential for photo-realistic rendering.

Towards Unbiased Volume Rendering of Neural Implicit Surfaces with Geometry Priors
Computer Vision and Pattern Recognition, 2023Learning surface by neural implicit rendering has been a promising way for multi-view reconstruction in recent years. Existing neural surface reconstruction methods, such as NeuS [24] and VolSDF [32], can produce reliable meshes from multi-view posed ...

Unbiased inverse volume rendering with differential trackers
ACM Transactions on Graphics, 2022Volumetric representations are popular in inverse rendering because they have a simple parameterization, are smoothly varying, and transparently handle topology changes.

Fast volume rendering with spatiotemporal reservoir resampling
ACM Transactions on Graphics, 2021Volume rendering under complex, dynamic lighting is challenging, especially if targeting real-time. To address this challenge, we extend a recent direct illumination sampling technique, spatiotemporal reservoir resampling, to multi-dimensional path space

In order to assess the reliability of volume rendering, it is necessary to consider the uncertainty associated with the volume data and how it is propagated through the volume rendering algorithm, as well as the contribution to uncertainty from the rendering algorithm itself.

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
Efficient visualization of large volumetric data is a challenge for image processing community. In this paper, we present a novel volume rendering algorithm based on the concept of fractal. It consists of dividing the volumetric data set into sub-blocks, calculating the 3D fractal coefficients of each sub-block, projecting them to 2D image plane, and ...

ACM SIGGRAPH Computer Graphics, 1988
A technique for rendering images of volumes containing mixtures of materials is presented. The shading model allows both the interior of a material and the boundary between materials to be colored. Image projection is performed by simulating the absorption of light along the ray path to the eye.

IEEE Transactions on Visualization and Computer Graphics, 2001
Presents a two-level approach for volume rendering, which allows for selectively using different rendering techniques for different subsets of a 3D data set. Different structures within the data set are rendered locally on an object-by-object basis by either direct volume rendering (DVR), maximum-intensity projection (MIP), surface rendering, value ...

The Visual Computer, 2015
Analyzing and processing various data types in a privacy-preserving perspective has been researched in many disciplines; however, such an issue draws very limited attention in the research field of scientific visualization. We wondered if it is possible to delegate the rendering of a volume data set to a remote server(s) while still being able to ...
