This research discusses the conversion of underground utilities datasets into scene graph models for its 3D visualization using the WebGL technology, which is a Javascript interface to access the 3D graphics hardware. This conversion requires to reconstruct the volumetric appearance of the objects from its abstract representation, involving several decisions towards its mapping into a scene graph. Each decision taken carries consequences in the rendering performance and given the nature of the underground utilities, multiple problems arise which should be addressed before achieving a fluid visual- ization. This research considers multiple reconstruction approaches and studies the corresponding factors affecting the performance by introducing a testing framework. With the results of the tests, the considered factors are ranked based on their performance and used to give advice towards the best approaches for the reconstruction underground utilities and its applicability to WebGL environments.
