Why 3D?

Why 3D?

Using different types of aerial, stationary, mobile and manual laser and optical tools, we scan all kinds of monuments, including architecture, sculpture, painting, artistic crafts, etc. They are accurate copies of the objects which actually exist.

Using dedicated software, w process raw scans into three-dimensional models containing texture. We create a grid model which contains a set of vertices, edges and surfaces which determine the shape of irregular objects (such as sculptures) in 3D computer graphics and block modelling.

By using reverse engineering, we can restore elements of historical artifacts (e.g. sculptures, ceramics, etc.) or recreate in detail the designs of architectural monument which never existed.

Finally, we create interactive educational applications which use the digital heritage resources generated in our projects. In this process, we strive to use the most advanced visualisation technologies, such as virtual and augmented reality (VR/AR) to make learning as attractive as possible.

Tools

Our main task in this project is two and three-dimensional digitalisation, inventory and virtualisation of historic sacred objects together with the elements of their equipment and development of descriptions of digitalised monuments which are adapted for educational, scientific and popularising purposes.

For this purpose, we use the latest technological advances, including:

Technology

Laser scanners

They are used to obtain information about the shapes, colours and sizes of historic architecture. Thanks to their fantastic speed (up to 1 million measurements per second), high measurement precision (the margin of error within 1-2mm) and specialised software, we are able to combine an unlimited number of scans, eventually obtaining a point cloud which is a true, digital copy of the monument.

Optical scanners

For the three-dimensional digitalisation of moving monuments, we use optical scanners of white and/or blue structural light with resolutions up to 0.01mm, to precisely capture the complex structure and colour of the artifact.

Drones

We use them in several ways. Industrial drones which are equipped with 45 MP cameras, are used for low-ceiling photogrammetry – creating precise, three-dimensional maps of urban areas in which, digitalised by us, architectural monuments are located. The ones equipped with a lidar are used to record point clouds of areas inaccessible from the ground (e.g. roofs and upper parts of towers). Finally, we use professional drones equipped with cameras with interchangeable lenses for filming the monuments in 4K-8K resolution.

Digital cameras

Depending on the effect we wish to achieve, we use medium and large format digital cameras with resolutions of 50-400 MP to make movies and time-lapse videos in 4K-8K, HDR spherical giga panoramas, gigapixel photographic documentation and gigapixel reproduction, with a resolution of more than 1 billion pixels.

Specialist cameras

We use them to obtain ultra-precise photography of painting in infrared (IR), ultraviolet (UV) roentgen (X-ray), micro and multispectral (FSI) technology.

Dedicated software

We use several types of specialised software to carry out a complicated process of registration, modelling and final generation of 3D models of monuments based on the obtained scans. The same applies to photo/video materials from digital cameras that require tedious and time-consuming processing.

Unity Engine

It is a multi-platform game engine for creating 2D and 3D computer games and other interactive materials, visualisations or animations. We use it to create advanced, interactive VR/AR visualisations of digitalised architectural monuments together with their historic interior design.
