MODELING

The project records the motions and stable points of a viewing camera in a digital modeling software as the designer orbits, pans, and manipulates the model. With each element created or modified in the model, an outline of the model from the perspective of the designer is projected onto a sphere centered on the model. The closeness of the camera is captured by the scale of the projection, so that as a viewer looks more closely at the model to match the projection with the object, they are in fact retracing the motions of the designer rotating and zooming in and out of the modeling software. What we have is a viewing camera that mimics the motion of the eye's saccadic movements the way a designer views a model in software. The tracing of these movements furthermore produces an artifact for digital models, offering a glimpse at the process of the artist in a similar way eraser marks and guide lines might when hand drafting.

 
 

To represent these curves in space in two dimensions, the projected curves (shown in red) are unrolled spherically (shown in blue), tracing in reverse the traces left from modeling. This is necessary because a stereographic projection would obscure the directions of travel, misrepresent distances of rotation, and distort objects. 

 
 

Unrolling

To physically show these objects, a Sphero was hacked to roll according to the geometry on its surface, producing both the inscription on its surface as well as the unrolled geometry on the floor. Several variations of the painting were done using paints and inks - the images below are a video and long exposure shot of the drawing process, both inverted and recolored.
