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.

“…Recently, many researchers are introducing machine learning techniques to learn the design skills of cartographic generalization by transforming vector map data into raster images, even for aggregation [FTS19, YAY*22], selection [SLW*22, XAY*23], and simplification [YYY*22].…”

Aggregation, as an operation of cartographic generalization, provides an effective means of abstracting the configuration of building features by combining them according to the scale reduction of the 2D map. Automating this design process effectively helps professional cartographers design both paper and digital maps, but finding the best aggregation result from the numerous combinations of building features has been a challenge. This paper presents a novel approach to assist cartographers in interactively designing the aggregation of building features in scale‐aware map visualization. Our contribution is to provide an appropriate set of candidates for the cartographer to choose from among a limited number of possible combinations of building features. This is achieved by collecting locally optimal solutions that emerge in the course of aggregation operations, formulated as a label cost optimization problem. Users can also explore better aggregation results by interactively adjusting the design parameters to update the set of possible combinations, along with an operator to force the combination of manually selected building features. Each cluster of aggregated building features is tightly enclosed by a concave hull, which is later adaptively simplified to abstract its boundary shapes. Experimental design examples and evaluations by expert cartographers demonstrate the feasibility of the proposed approach to interactive aggregation.

“…Assim, a generalização cartográfica no âmbito digital deve ser subdividida em um conjunto de operadores de generalização (SHEN et al, 2022) capazes de solucionar problemas muito específicos automaticamente (BANASIK; CHROBAK; BIEGUN, 2022). Isso pode acarretar dificuldades quando se muda o BDG primário e as suas características geométricas e/ou estatísticas não refletem o conjunto anteriormente analisado.…”

“…A finalidade da generalização é produzir mapas respeitando requisitos de exatidão, conteúdo de informação e legibilidade (MCMASTER; SHEA, 1992;. Esse processo está fortemente conectado às representações multi-escala e a multi-representações (Level of Details -LoD, no contexto digital) de um mesmo conjunto de dados (BILJECKI et al, 2016;TANG et al, 2020;SHEN et al, 2022). A generalização cartográfica, portanto, é o processo empregado para tratar dados geoespaciais de entrada e representá-los em escalas múltiplas, obtendo representações facetadas, desenvolvidas e aplicadas, conforme necessidade e objetivos do produtor de um mapa, sendo correspondente às regras impostas por um determinado nível de abstração (SESTER, 2020).…”

Conceitos e procedimentos relacionados ao tema de generalização cartográfica evoluíram nas últimas décadas. Originalmente, este processo era aplicado no contexto analógico para garantir a manutenção da visualização e comunicação cartográfica de forma adequada. No entanto, com o avanço da cartografia digital o paradigma é ampliado e, então, o processo é aplicado desde a concepção do produto cartográfico, ou seja, quando se deseja reduzir uma base de dados para um mínimo necessário, mas mantendo as propriedades espaciais relevantes do conjunto. Computacionalmente, as regras de generalização são expressas por meio de algoritmos computacionais que incluem aspectos de semântica e geometria, assim como exigem, além de formulações objetivas, análises subjetivas de difícil implementação e automatização. Além disso, a inserção de novas tecnologias de aquisição e processamento de dados geoespaciais produzem novas lacunas científicas a serem superadas. Nesse aspecto, este trabalho busca, a partir de uma pesquisa bibliográfica e bibliométrica, identificar como as novas tecnologias ampliam os desafios relacionados à generalização cartografia. Observa-se que, apesar dos operadores de generalização serem considerados satisfatórios, o número de publicações na temática é crescente e apresenta interesse internacional. Ademais, as novas tecnologias como algoritmos de Inteligência Artificial, aquisição de dados geoespaciais de forma incremental e construções de representações 3D inserem complexidades teóricas e práticas que devem ser superadas. Logo, os avanços da generalização cartográfica dependem da implementação de soluções relacionadas à materialização computacional dos operadores de generalização em processos objetivos que permitam a compreensão imediata da relação geométrica e estatística formada por um conjunto de dados geoespaciais.
