AbstractIn this work we present a new software platform for interactive volumetric visualization of complex architectural objects and their applications to teaching and training conservation interventions in Architectural Cultural Heritage. Photogrammetric surveying is performed by processing the information arising from image- and range-based devices. Our visualization application is based on an adaptation of WebGL open standard; the performed adaptation allows to import open standards and an interactive navigation of 3D models in ordinary web navigators with a good performance. The Visualization platform is scalable and can be applied to urban environments, provided open source files be used; CityGML is an open standard based on a geometry -driven Ontology which is compatible with this approach. We illustrate our results with examples concerning to very damaged churches and a urban district of Segovia (World Cultural Heritage). Their connection with appropriate database eases the building evolution and interventions tracking. We have incorporated some preliminary examples to illustrate Advanced Visualization Tools and architectural e-Learning software platform which have been created for assessing conservation and restoration tasks in very damaged buildings. First version of the Advanced Visualization application has been developed in the framework of ADISPA Spanish Project Results. Our results are illustrated with the application of these software applications to several very damaged cultural heritage buildings in rural zones of Castilla y Leon (Spain).
