A Monte Carlo code for the calculation of light transport in heterogeneous scattering media is presented together with its validation. Triangle meshes are used to define the interfaces between different materials, in contrast with techniques based on individual volume elements. This approach allows to address realistic problems in a flexible way. A hierarchical spatial organisation enables a fast photon-surface intersection test. The application of the new environment to evaluate the impact of the trabecular structure of bone on its optical properties is demonstrated. A model of the trabecular micro structure recovered from microCT data was used to compute light distribution within tissue. Time-resolved curves across a spherical bone volume were computed. The work presented enables simulation of radiative transport in complex reality-based models of tissue and serves as a powerful, generic tool to study the effect of heterogeneity in the field of biomedical optics. 547-560 (1998 193-206 (1998). 24.

Abstract:We present a new approach to illuminate and render single scattering effects in heterogeneous participating media in real time. The medium's density is modeled as a sum of radial basis functions, and is then sampled into a first volumetric grid. We then integrate the extinction function from each light source to each cell in the volume by a fast cell-to-cell propagation process on the GPU, and store the result in a second volume. We finally render both scattering medium and surfaces using a regular step ray-marching from the observer to the nearest surface. As we traverse the medium, we fetch data from both volumes and approximate a solution to the scattering equation. Our method is real-time, easy to implement and to integrate in a larger pipeline.

Abstract-We describe a novel volumetric global illumination framework based on the Face-Centered Cubic (FCC) lattice. An FCC lattice has important advantages over a Cartesian lattice. It has higher packing density in the frequency domain, which translates to better sampling efficiency. Furthermore, it has the maximal possible kissing number (equivalent to the number of nearest neighbors of each site), which provides optimal 3D angular discretization among all lattices. We employ a new two-pass (illumination and rendering) global illumination scheme on an FCC lattice. This scheme exploits the angular discretization to greatly simplify the computation in multiple scattering and to minimize illumination information storage. The GPU has been utilized to further accelerate the rendering stage. We demonstrate our new framework with participating media and volume rendering with multiple scattering, where both are significantly faster than traditional techniques with comparable quality.
