with VideaLab

Last modified: September'12

This is a list of the most ineresting projects I have been working on VideaLab since 2003. We were a technical team, mostly formed by software engineers, but also by architects, civil engineers, historicians, designers and artists, and is the whole team who get this works come to life. I will try to explain what were my tasks and what interesting aspects were in its development.

Most VideaLAB works use a mix of the technologies, as our realtime terrain visualization engine SANTI, our libraries for virtual reality, IO devices, 360º photo and video visualization, natural interfaces, computer vision, etc., made from the scratch in more than ten years of software development.

Architectural modelling, realtime rendering, advanced shading, multitouch surfaces, multiaxial 3d model cutting, multitouch.
Shows: P
ermanent exhibition at CITIC building.
Description: The use of multi-touch surfaces is not yet widespread in the field of architectural visualization. This project applies this technology to the visualization of the two buildings that make up the IT and Communications Research Centre (CITIC),of the University of La Coruña. This way, the buildings can be look round in real time with natural interaction with the user, using a multi-touch device based on FTIR technology.
The experience with this model is not simply limited to the exploration outside the building, but can go into it virtually and analyze it as a whole through a system of interactive sections. You can also access to additional information activating contextual elements, interaction with visitors, and information systems of the various laboratories and offices in real time.

Uses and shows: Used as a technical tool and also for showing to population the actions in this field (Malpica).
Description
Notes: This project was interesting enought to publish a paper about some of the techniques we developed on it. The application was intended to study the environmental visual impact that some fish farms would do over the surrounding landscape, located in the Galician coast.
All of this is perfectly described in [the paper], but to summarize this meaned two main problems: the vegetation simulation and the analysis algorithm. The first one was solved by a semi-automated tool, which let the user to paint closed polylines on the tree mass, and automatically 3D billboards some random size, at its right elevation over the terrain, and with a density parameter. The texture applied were pics autochthonous tress from a library.
The analysis algorithm was inspired in the CG well known raytracing algorithm. Some specific points were chosen to calculate the visibily, that was represented by the shadow generated over the terrain if an omni light is located in that place. Also, we calculated the inverse operation, by distributing a big number of lights over the volume of the buildings.
The resulting application was used both for public shows and as an analsys tool, as trees could be added in strategic places to reduce impact, and the planify their planting.

Description: The installation designed for this application simulates a magical natural fountain located inside a cave, which has some ancient ruins. The fountain has been placed on a platform, which confers an altar-like apparance to it.
There is a hidden system which analyzes simultaneously the images of up to 8 user's hands.The analysed pictures are taken by two cameras located in the vegetal top structure.
A two-meter-long irregular-shaped screen in the background reflects the upward mirrored images emitted by two projectors located underneath the platform that supports the whole set. In order to get a continuous high-resolution image, images are blended in along the whole surface.
This system is based on a computer control application which transforms the position and hand movements of all users into the equivalent movement of 8 simultaneous cursors acting on the contents, so that it must be able to create a thread for each one of the participants, in such a way that each visitor has the feeling that the fountain is replying to their particular movements, as well as to those of the other users.
