Live Visual Magic

by Aalto University (Helsinki, Finland)

In this course participants create a show of live visuals made of 3D motion graphics based on their interests.

The workshop relies on the theory of the audio-visual, used as a basis for expressing synaesthetic experience through the use of 3D motion graphics and real-time performance software. Through exploring their own interests in a systematic manner the course participants work through the vast possibilities offered by the digital content creation software in a way that helps them to stay focused while building a more nuanced understanding of the phenomena they are trying to understand and express. Through the tasks they can develop understanding of both the software and the requirements of audiovisual live performance.

Planning
1, Each participant creates a clipbook based of personally interesting aesthetics. In the clipbook include images of specific objects or entities related to that aesthetic. Write out the names of the entities and include links to further information about them.
2, Select 4–6 objects or entities to be modeled in a 3D application; using only geometric primitives such as spheres, cubes, cylinders and such, sketch them out on a paper using a pencil from three views: front, side, and top.

Content Production
3, Start modeling the objects in a 3D application. Make iterations; sometimes it’s best to start over with new information. Consider blocking of the masses, as well as texturing and lighting
4, Create a number of looping animations for the objects. These can be simple, one full rotation around the vertical axis for example.
5, Render out videos in a format that supports transparency, such as ProRes 4444, DXV3 or HAP.

Performance
6, Load the rendered videos into a VJ app or other media processing and remixing software. Overlay them on top of each other and manipulate their position, scale, rotation, and transparency in real time.
7, Select some music into a collaborative playlist to play aloud.
8, Connect to a projector and project the mix of videos on a suitable surface while manipulating the effect parameters along to the music.

A classroom or office setup featuring a projector placed on a transparent plastic box on a table. The projector is turned on, casting colorful and abstract purple and yellow visuals onto vertical blinds in the background. On the table, there is a laptop with stickers and a bottle of soda, along with cables and other miscellaneous items, suggesting an experimental or creative workspace.
