Representation of a three-dimensional integrated survey of the Casa De Vidro by Lina Bo Bardi in São Paulo, Brazil | Original Article

ABSTRACT:

This paper describes the method and the process used for the representation of the integrated digital survey of the Casa De Vidro by Lina Bo Bardi in São Paulo (Brazil), carried out in 2017 by the DIAPReM (Development of Integrated Automatic Procedures for Restoration of Monuments) Department Center of the University of Ferrara. It is part of a Master‟s degree thesis which had as its objective the valorization of the site as a museum. After a brief description of the house and an introduction to the thesis work, the text describes the characteristics of the laser scanner survey and the method of extracting raster images as a support for architectural drawings. Subsequently, the strategy of representing the complex topography of the site is explored, aiming at the production of the situation plan. Given the importance of the tropical garden that surrounds the house, a further study concerns the representation of the vegetation on the vertical plane. The process that leads to the vectorization of the profiles of the landscape starting from the extractions from the point cloud is described in detail. Then it is exposed the treatment of the raster image with the visualization in false colors of the reflectance data through filters to bring the colors to shades of green. By assembling the trees together, it is possible to get drawings that best represent the vegetation and the insertion of the architecture in the tropical garden. It is noted that, due to the high density of trees, it would not be possible to create a representation corresponding to each one of them. These circumstances forced to choose specific specimens and to repeat them in the overall elaborates.
