Controlling laser show projectors via the ILDA protocol is a challenging but rewarding approach. Tim Greiser, co-creator of Laser Juice, will break down what you need to know to get started using TouchDesigner with Ether Dream or Helios DACs in order to produce beams, abstracts, or interactive tools with laser light. Greiser will provide theory, terminology, protocol and hardware details, and will provide example code for working with SOPs, CHOPs, or TOPs. The pros and cons of each domain will be discussed. Participants will learn about topics like scan rate, blanking, color signal techniques, and vector scanning.

This will be a hands-on session where small groups will form to build projects on virtual scopes that will eventually be displayed with lasers. At the end of the workshop the group will engage in a discussion about the results and challenges of their experimentation.
