Projection mapping
Where is projection mapping used?
Large scale on buildings and architecture
Small scale on objects. (see examples)
Dome projections with sound
Projection mapping is a technique used to project video or other digital content onto irregularly shaped surfaces or objects. It can be used to create immersive, interactive installations, and to enhance the visual impact of performances and live events. The artistic purpose of projection mapping can vary widely, depending on the specific project and the artist or designer's intent. Some artists use projection mapping to create interactive installations that allow viewers to engage with the artwork in new ways. Others use it to create large-scale, immersive environments that transport viewers to other worlds or to create an atmosphere. It can also be used to enhance live performances, such as music concerts or theater productions, by creating dynamic visual backdrops that enhance the overall experience. Some artists use it to make buildings, sculptures, and other architectural elements come alive with light and movement.
Projection mapping is often used in combination with audio and music in live performances, events, and installations. Some examples include:
Concerts and music festivals: Projection mapping is often used as a visual element in live performances, to enhance the overall experience for the audience. For example, it can be used to project images, animations, and videos on the stage or on the background behind the performers.
Multimedia theater productions: Projection mapping is used in multimedia theater productions to create dynamic and immersive visual environments. This can include projections on the stage, on the floor, or on the ceiling.
Public art installations: Projection mapping is used in public art installations to transform architectural spaces and landmarks into dynamic, interactive experiences.
Interactive installations: In interactive installations, projection mapping is often used to create interactive experiences where the audience can interact with the visual elements through movement, touch, or other forms of input.
Museum exhibits: projection mapping is used in museum exhibits to create immersive and interactive experiences that enhance the visitor's understanding of the subject matter.
Advertising and branding: projection mapping is also used as a form of advertising and branding, to create large-scale, dynamic displays that capture the attention of audiences and create an impactful visual experience.
Sometimes sound and visual projections are combined.

Projection Mapping with Touchdesigner (1): KantanMapper
KantanMapper is a component in TouchDesigner that allows users to map video content onto 2D or 3D surfaces by creating and adjusting corner points and edges through a visual interface. It provides real-time mapping capabilities where users can specify source regions in the input video and map them to destination regions on the target surface
Assignment
Build a network in TouchDesigner to project on three sides of a simple cube. The network should be able to receive OSC messages from SuperCollider that will switch between different video(bitmap) content for each side of the cube. Let SuperCollider contribute interesting sound to this audiovisual setup. How are your sounds related to the switching content?
