We evaluate three Open-Source WebGL frameworks (X3DOM, three.js and Cesium) and investigate their use for geospatial applications in the Web. Over the course of one year we carried out five case studies and developed different software prototypes using these frameworks. We focus on geospatial applications since they require unique features that bring the evaluated WebGL frameworks to their limits. Geospatial data is typically heterogeneous and very large. Geospatial applications require special data management and interaction techniques. We describe the criteria that we defined to test the WebGL solutions and present our experience from working with them. We give a qualitative comparison and finish the paper with conclusions and an outlook on future research perspectives.

The 3D Surface representation (S-rep) can be employed to illustrate solid models of physical objects. 3D S-reps have been successfully used in CAD/CAM, and in conjunction with texture mapping, in the modern gaming industry to customize avatars, improve the gaming realism and sense of presence. Current healthcare systems require patient specific information sharing for planning, training and patient education. We are proposing a cost effective method to generate patient specific S-reps and convert them to optimized X3D models in the context of medical simulations for planning, training and patient education. We assess the accuracy of the S-rep and its potential for inclusion in Web3D-based interactive medical simulations. We exemplify with an interactive X3D tool for medical planning and training of the complex X-Ray and Proton therapy procedures.
三维表面表示(S-rep)可以用来说明实体模型的物理对象。3D s -rep已经成功地应用于CAD/CAM中，并与纹理映射相结合，在现代游戏行业中定制化身，提高游戏的真实感和存在感。当前的医疗保健系统需要患者特定的信息共享来进行规划、培训和患者教育。我们正在提出一种具有成本效益的方法来生成患者特定的s -rep，并将其转换为医学模拟环境中的优化X3D模型，用于规划、培训和患者教育。我们评估了S-rep的准确性及其在基于web3d的交互式医学模拟中的潜力。我们以交互式X3D工具为例，用于复杂x射线和质子治疗程序的医疗计划和培训。

There are many building energy simulation systems on the market today; however, most of them rely on theoretical thermal models to make decisions on the building structural design and modifications. Sustainable methods of construction have made tremendous progress in the recent decades. The example of the German Energy-Plus-House technology uses a combination of (almost) zero-carbon passive heating technologies. A web-enabled X3D simulation system coupled with a cost-effective set of temperature/humidity sensors can provide valuable insights into building design, materials and construction that can lead to significant energy savings, an improved thermal comfort for residents and improved efficiency. We propose a cost effective hardware-software prototype system that can provide real data driven 3D thermal maps for residential buildings. The system can easily scale to provide 3D thermal maps for large commercial buildings.
