For my self portrait, I used Grasshopper to merge data from the Kinect (through Quokka) and from GIS map data (through the Meerkat Grasshopper plugin<\/a>).<\/p>\n

I first took a Kinect portrait of myself as a point cloud, baking it to keep it static. \u00a0Then I took that point cloud back into Grasshopper and generated a Delaunay mesh from it. \u00a0The mesh came out best when I manually rotated the point cloud in Rhino to be horizontal – but there were still some extra faces I had to delete between my hair and my face. \u00a0I then used the Mesh2NURB tool in Rhino to convert the mesh to a nurb sufarce.<\/p>\n

Separately, I found the Grasshopper plugin Meerkat GIS<\/a> on the Food4Rhino website. \u00a0Meerkat allows you to parse map shapefiles in Grasshopper and turn them into points, curves, or meshes.<\/p>\n

I went on MapZen and got shapefiles<\/a> for New York City (shapefiles are basically the map geometry data and metadata for an area). \u00a0I used the OSM2PGSQL SHP download after searching for New York.<\/p>\n

I then used Meerkat to select a portion of\u00a0my neighborhood of Prospect\/Crown Heights and bring that data into Grasshopper as curves.<\/p>\n

\"face2\"<\/a><\/p>\n

I then combined these two things manually in Rhino. \u00a0I extruded the curves of the map and then boolean intersected them with the nurb surface of my face.<\/p>\n

Here’s what my Grasshopper layout looked like:<\/p>\n
