A proof-of-concept collection of patches that shares polygon mesh geometry from Grasshopper to TouchDesigner in realtime via OSC. The ability to share mesh data between Grasshopper and TouchDesigner allows for a streamlined workflow when projection-mapping geometry. It eliminates a mesh export/import step, and doesn't rely on TouchDesigner's mesh editing tools. It streamlines the process of fabricating objects, as it closely links the fabrication process of the form to the projection mapping process. Grasshopper, a parametric geometry environment, allows for great control over the verticies, planes, and normals of a 3D mesh, which gets sent to the TouchDesigner graphics environment. Any changes to a mesh done in Grasshopper translates to TouchDesigner in real time. This is a proof of concept and unoptomized for large meshes.
