The baroque theatre, which is situated at the fifth courtyard ot the Český
Krumlov castle, is original, completely preserved baroque theatre scene.
The unique technology for changing the coulisses and other decorations were
made by Viennese carpenter Lorenz Makh (more at [1]).

This graduation project is a part of long-lasting work,
which runs as a collaboration of Fotogrametrical Laboratory of the Map and
Cartography Department of the Civil Engineering Faculty of the Czech Technical
University, Administrative Unit of the Český Krumlov Castle and the Foundation
of the Baroque Castle. In previous years there was the aim to create a digital
3D model of the theatre (Picture no. 1), which should help with presentation,
research and maintenance of the theatre in future. The whole project is
called Living theatre (the same name as my work) - the result should be
high dynamic spatial model of this unusual object. The Client, who assigned
this project is Administrative Unit of the Český Krumlov Castle.
I chose the topic - Visualization of the baroque theatre in Český Krumlov - in year 2003. I converted the spatial data from format of Microstation program (DGN) to format VRML within one of school subjects. The main aim ot this semestral project was walking through the virtual model in real time with a sufficient continuity ot the show. This virtual model contained only the part of baroque theatre, which is in front of the stage.
This semestral project interested me so much, that I decided to carry on as far as it developed into a graduation project. The stage space was added to previosly created model and the whole work was extended with a program part. This means the neccesary base for investigation of the object.
The visualization fulfils requirements for easy usage of the 3D model. It means: usage of the well-known and well-tried format of data, the speed of displaying and walking through the model and a possibility of visualization at different computers ( so-called Removal ). The topic of the speed of displaying of virtual model is closely linked with specificity of the model. There is always a compromise between the speed and the specificity of the show. I accepted all these parametres at the real begining of the project.
There is still a big amount of technical equipement in the theatre, which is interestig for a research. It is neccesary to investigate these objects from different point of view and to search the continuity and possible relations among details. In real application it means to study plans, photographs and sketches, which are not open to public. The spatial imagination is neccesary as well. Prospective restauration and making copies is expensive. I would like to alert, that my project does not substitute the original possibilities of the object investigation, it only infillls the area with other possibilites.

One of the basic client´s requirements was the distance measurement (Picture no. 2). Within the scene there could be measured not only the distances of the two points, but also the distances of their nearest apexes of the chosen model. For a higher comfort during the work with the model it is neccesary to have specific tools for categorization according to different criterions. According to these it is possible to clearly search required elements of the model and work with them. The information about the elements of the model are closely connected with that - information in XML file.
