Video Mapping, 3D Photogrammetry, Anamorphic Images, LandArt

My name is Ugo Cassanello

I am an independent 3D artist, projectionist, passionate about analog and digital video mapping, Multimedia Shows design, 3D modeling by photogrammetry, and anamorphic optic illusion Land Art.

I define the digital mapping layout giving feedback about  projectors type, position, inclination and rotation, lenses, zoom value, lens shift, light power output in lumen per square meter and pixel size in a specific area of the screen and I give all the information and images needed for content creation.

My job is to set up the projection layout. How many projectors do we need ? What is their best position ?


I am the bridge between graphics designers who will create the content and the media server that will bring the image to the screen.


I can drive artists that want to create video mapping content even if they have no video mapping skills.


In the video mapping section of this site you can find a lot of digital and analog video mapping examples, on buildings, water screens, tv stages, stadiums, from one to more than one hundred video projectors.

Almost all on this site is about video mapping. In order to achieve the video mapping process I need to have a perfect 3d model of the screen to project to. Using photogrammetry I can build an accurate 3d textured model and also get informations about the surrounding areas, including the video projectors, control room and audience location.

My way to do photogrammetry is based on spherical 360°photos.


The first step of the process is to go on site and take several interesting 360° panoramic photos using a fixed lens camera mounted on a panoramic head. If you click the thumbnail on the left you can open an example of panoramic photo in full screen.

To navigate inside the photo you can click and drag. To change the zoom level you can use the mouse wheel or SHIFT and CTRL on your keyboard.


Then, in dedicated softwares I find the position of each panoramic photos in a virtual 3d environment by adding points, like a custom point cloud, that  will help me to make the final 3d model.


I import the scene (a point cloud and as many cameras than spheric photos) in my preferred 3D software. I can now draw the model in 3d by looking trough those spherical photos.

Sometimes, as in the image below on the left, the whole video mapping screen came from a 3d scan.

Sometimes, as on the right, only a part of the projection screen (details in magenta) came from a 3d scan. The rest of the 3d model is made by hand with photogrammetry or other techniques.

Accurate and precise 3d models to simulate multimedia shows, including control rooms, projection rooms, technical rooms, corridor trench, cable trays, workshop, backstage, led screens, water screens, laser and video projection, audience point of view of the show and everything else is needed to help the comprehension and the communication with the client.

Amazing stunning optical illusion, flat or in volume, that will be seen from an unique point of view.

I draw those anamorphic images in 3d using techniques that came from video mapping. Doing so I make simulations of those amazing giants images giving back informations about how to built them in the real life.


Some of those images are in volume, others are flat.


The beauty of those projects is that they can be seen by day and night without any power supply during their exploitation, unlike video mapping projects.


Also, the audience can be both at the point of view that reveal the image, taking pictures, and into the image, becaming a part of the image itself.
