THE LOUVRE - INSTALLATION - PART 2
POST PRODUCTION AT GPS
The Louvre Project showcases Mark Lewis’s unique way of immersing the viewers in real environments.
Taking us through one of the most beautiful interior environments in the world, this project for the Louvre showcases Mark Lewis’s unique way of immersing viewers in real environments.
Our team at Gramercy Park Studios made use of the latest technologies in image acquisition, geometry extraction, 3D modelling and digital paint that allowed the Director to blend together live action and virtual environments. This was a challenging and engaging project from both an artistic and technical point of view. The end result is a unique tour of the Louvre.
In order to help the Director decide how to best film this project, the team at Gramercy Park Studios started by creating a low res version of multiple parts of The Louvre. This low res version was used by Mark to work out how navigate through the space and decide which kind of camera rig, camera moves and speed he would use for the main shoot and the rooms he would build digitally.
Our team visited the Louvre multiple times to perform an extensive photographic capture of the environments that Mark had selected. From these reference photos the high resolution textures and geometry were extracted using a photogrammetry workflow. Hundreds of photos were calibrated to put them in the exact position within the virtual 3D space. From this calibration the team was able to extract a base geometry and a 'point cloud' from which the precise 3D models were created.
The exact textures of the Louvre could then be re-projected, edited, digitally enhanced and mapped onto the 3D models.
During the live action shoot our team was on set supporting the Director in order to ensure there was a seamless blend between the live action footage and the virtual environment.
This allowed for a perfect integration of all the elements and to portray a unique voyage through this intricate space that Mark Lewis first imagined at the beginning of the project.
