Photo-realistic, physically consistent 3D modeling and interactive display of astronomical objects for digital planetariums

这项研究项目旨在开发物理上一致的、真实天文星云的三维建模和绘制方法。虽然在第一个资助期，我们开发了根据观测图像数据重建和可视化可信的静态三维模型的方法，但我们计划在第二个资助期使用测量的P-V谱数据和流体动力学模拟技术，以便包括天文星云的时间演变和重建动态体积模型。此外，受支持物体的类别将由反射星云扩展，在特定情况下，反射星云的三维几何形状可以从星云内的光回波确定。为了最大限度地利用现代数字天文馆的分辨率和显示质量，我们计划开发自动化和交互技术，以科学合理和可信的方式提高重建模型的细节程度。我们的目标是充分利用现代数字天文馆提供的机会：通过我们重建的动态模型，我们将以一种视觉上令人印象深刻但具有科学意义的方式向广大观众展示这些天文天体和宇宙现象。

This research project aims at developing methods for physically consistent, three-dimensional modeling and rendering of real astronomical nebulae. While, in the first funding period, we have developed methods for reconstruction and visualization of plausible static 3D models based on observed image data, we plan for the second funding period to employ measured P-V spectral data and hydrodynamic simulation techniques in order to include the temporal evolution of astronomical nebulae and reconstruct dynamic volume models. In addition, the class of supported objects will be extended by reflection nebulae whose three-dimensional geometry can, in specific cases, be determined from light echoes within the nebulae. To make optimal use of the resolution and display quality of modern digital planetariums, we plan to develop automatic and interactive techniques to increase the degree of detail of reconstructed models in a scientifically well-founded and plausible way. Our objective is to make full use of opportunities provided by modern digital planetariums: with our reconstructed dynamic models, we will illustrate those astronomical objects and cosmological phenomena for a broad audience in a visually impressive, yet scientifically profound way.
