Since the Belt and Road Initiative was proposed, it has received extensive attention from many aspects of the international community. To disseminate the ideas, development status, and construction achievements of the Belt and Road Initiative to the outside world has become a key and difficult problem in the development process of the initiative. Among different types of film and television, virtual reality technology should be the best interpretation of film communication. e film would bring a wider space for the development of the film by means of real reproduction and virtual reality and make the film's record form more diversified.e continuous development and innovation of new media technology enable virtual reality to pass through panoramic lenses. As the most powerful technical support for the movie, it can even be converted into the user's eyes to serve the movie so that the presentation of the movie has more new possibilities. In this context, the article aims to interpret the visualization practice and dissemination effects of digital Chinese films with virtual reality technology.e article used the mathematical expression of the visual SLAM problem to improve the process from the world coordinate system to the pixel coordinate system. e system is constructed, and the approximate calculation of the function is carried out. e constructed system was used in the experiments. is article conducts a survey of Google's average popularity and a comparison of the voxelization process. e experimental data showed that the performance of Sponza in this branch of the sparse octree is 88.48 ms at the resolution of 100,000, which is weaker than 80.34 ms in the Dragon scene. e performance of the cascaded voxel texture is 6.889 ms, which is also weaker than Dragon's 5.727 ms. e structure of the rules of the cascaded voxel texture scheme made it smoother to assist with the GPU, and the speed was the fastest in both the Dragon scene and the Sponza scene. e experimental content was well completed.

We report on an ongoing collaboration between epidemiological modellers and visualization researchers by documenting and reflecting upon knowledge constructs—a series of ideas, approaches and methods taken from existing visualization research and practice—deployed and developed to support modelling of the COVID-19 pandemic. Structured independent commentary on these efforts is synthesized through iterative reflection to develop: evidence of the effectiveness and value of visualization in this context; open problems upon which the research communities may focus; guidance for future activity of this type and recommendations to safeguard the achievements and promote, advance, secure and prepare for future collaborations of this kind. In describing and comparing a series of related projects that were undertaken in unprecedented conditions, our hope is that this unique report, and its rich interactive supplementary materials, will guide the scientific community in embracing visualization in its observation, analysis and modelling of data as well as in disseminating findings. Equally we hope to encourage the visualization community to engage with impactful science in addressing its emerging data challenges. If we are successful, this showcase of activity may stimulate mutually beneficial engagement between communities with complementary expertise to address problems of significance in epidemiology and beyond.

“…For scattering at molecules of the Martian atmosphere, we opted for a similar approach to Costa et al, computing the refractive index and molecular number density from the average temperature, pressure, and gas composition of the Martian atmosphere [CBE*21]. The resulting parameters are given in Table 1.…”

Most real‐time rendering models for atmospheric effects have been designed and optimized for Earth's atmosphere. Some authors have proposed approaches for rendering other atmospheres, but these methods still use approximations that are only valid on Earth. For instance, the iconic blue glow of Martian sunsets can not be represented properly as the complex interference effects of light scattered at dust particles can not be captured by these approximations. In this paper, we present an approach for generalizing an existing model to make it capable of rendering extraterrestrial atmospheres. This is done by replacing the approximations with a physical model based on Mie Theory. We use the particle‐size distribution, the particle‐density distribution as well as the wavelength‐dependent refractive index of atmospheric particles as input. To demonstrate the feasibility of this idea, we extend the model by Bruneton et al. [BN08] and implement it into CosmoScout VR, an open‐source visualization of our Solar System. In a first step, we use Mie Theory to precompute the scattering behaviour of a particle mixture. Then, multi‐scattering is simulated, and finally the precomputation results are used for real‐time rendering. We demonstrate that this not only improves the visualization of the Martian atmosphere, but also creates more realistic results for our own atmosphere.
