A quasi optimal reconstruction algorithm based on the clipping is analyzed for Sampling-Reconstruction Procedure of realizations that compose a Gaussian process. Clipping means that it knows just the zero crossings in the realization. To find out its effectiveness, it is compared with an optimal algorithm, which considers some samples of the realization located at strategic points. Results show that the quasi optimal algorithm does not give a correct reconstruction. Hence, it is necessary to include a new parameter within this methodology to improve the performance, mainly reflected in the reconstruction error. However, the quasi optimal algorithm is just an approximations to the optimal algorithm.

The development of a virtual reality app based on the old English Pantheon, located in the Magic Town of Real del Monte, Mexico, is addressed in this text. The purpose of the project is that people can take a virtual tour through the pantheon with a smartphone to know the charm and mystery of its tombs, as well as digitally preserve the place in spite of its continuous deterioration over time. All the stages of the creation of the virtual scenery are described in detail, such as: storyboard, 3D modeling, UV mapping, texturing, lighting, and rendering; as well as the stages to realize the application in virtual reality, such as: camera adaptation, plugins’ installation, creation of scripts, relation of camera to the character, and creation of the Android APK. This app offers new ways of advertising historical places of the region and, at the same time, promoting tourism
