Abstract

The heritage values of Levantine rock art, as UNESCO World Heritage since 1998 and as an Asset of Cultural Interest since 1985 according to the Spanish Heritage Act, together with its fragile nature, demand developing initiatives aimed at regularly revisiting and monitoring the sites and updating any existing records (descriptions, tracings, photographs, etc.). This is especially important for long-known sites, such as La Joquera, discovered and first graphically recorded in 1930 and for which these records have not been updated for decades. Such revisits should be aimed to: a) asses the integrity of the finds since their discovery or since the last revision; b) test whether current digital technologies can improve previous interpretations and reproductions of the art preserved there; and c) produce accurate three-dimensional (3D) photorealistic models that capture the 3D nature of this heritage and even improve the visualisation of motifs. These integral approaches are relevant to the qualitative and quantitative study of the art, as well as to its preservation and monitoring, and creation of digital archives to ensure a virtual future for Levantine art. This paper reports the technologies and methods used, the challenges faced (in terms of space available, lighting restrictions and the visual interference caused by the protective fence), and the results obtained at La Joquera rock art site as part of the 2D and 3D digital recording of the rock surface, the colour and the motifs depicted. Highlights of this paper include the identification of previously invisible weaponry and adornments of the only archer preserved on this site, as well as some other incomplete remains. Deliverables also include the production of a photorealistic model on which colour-intensified tracings are projected. This facilitates the identification of art that is now extremely faded and offers a closer look at what the site may have looked like originally.

对 La Joquera Levantine 岩石艺术（卡斯特略省博里奥尔）进行数字增强和摄影测量记录

根据《西班牙遗产法》，黎凡特岩画自 1998 年起被联合国教科文组织列为世界遗产，自 1985 年起被列为具有文化价值的财产，其遗产价值及其脆弱的性质要求制定旨在定期重访和监测遗址并更新现有记录（描述、描摹、照片等）的举措。这对于一些久负盛名的遗址尤为重要，例如拉约凯拉遗址，该遗址于 1930 年被发现并首次进行了图文记录，但几十年来这些记录一直没有更新。这种重新考察的目的应当是：a) 评估自发现以来或自上一次修订以来所发现文物的完整性；b) 检验当前的数字技术是否能够改进以前对保存在那里的艺术品的解释和再现；c) 制作精确的三维（3D）逼真模型，以捕捉这些遗产的三维特性，甚至改进图案的可视化。这些综合方法适用于艺术的定性和定量研究，也适用于艺术的保护和监测，以及创建数字档案以确保黎凡特艺术的虚拟未来。本文报告了在 La Joquera 岩石艺术遗址使用的技术和方法、面临的挑战（可用空间、照明限制和保护性围栏造成的视觉干扰），以及作为岩石表面、颜色和图案二维和三维数字记录的一部分所取得的成果。这篇论文的亮点包括确认了以前看不到的武器和该遗址保存的唯一弓箭手的装饰品，以及其他一些不完整的遗迹。成果还包括制作了一个逼真的模型，并在该模型上投射了色彩强化描摹。这有助于辨认现已极度褪色的艺术品，并可近距离观察遗址最初的面貌。

期刊介绍： Virtual Archaeology Review (VAR) aims the publication of original papers, interdisciplinary reviews and essays on the new discipline of virtual archaeology, which is continuously evolving and currently on its way to achieve scientific consolidation. In fact, Virtual Archaeology deals with the digital representation of historical heritage objects, buildings and landscapes through 3D acquisition, digital recording and interactive and immersive tools for analysis, interpretation, dissemination and communication purposes by means of multidimensional geometric properties and visual computational modelling. VAR will publish full-length original papers which reflect both current research and practice throughout the world, in order to contribute to the advancement of the new field of virtual archaeology, ranging from new ways of digital recording and documentation, advanced reconstruction and 3D modelling up to cyber-archaeology, virtual exhibitions and serious gaming. Thus acceptable material may emerge from interesting applications as well as from original developments or research. OBJECTIVES: - OFFER researchers working in the field of virtual archaeology and cultural heritage an appropriate editorial frame to publish state-of-the-art research works, as well as theoretical and methodological contributions. - GATHER virtual archaeology progresses achieved as a new international scientific discipline. - ENCOURAGE the publication of the latest, state-of-the-art, significant research and meaningful applications in the field of virtual archaeology. - ENHANCE international connections in the field of virtual archaeology and cultural heritage.
