S I G N & D I G I T A L G R A P H I C S • December 2017 • 41 Figure 3: Create a template layer from the photo. Figure 4: Changing the subdivision in the Guides and Grid Preferences menu produces a more accurate matrix in which to draw the triangles. Low-Poly Set Up Go to the Preferences menu and choose Guides and Grid (see Figure 4). Set the number of subdivisions to 10. Too large a grid will produce a less refined image. The more subdivisions you choose the more closely your drawing can poten- tially match the photo however, too many polygons can create a lot more work. Uncheck the Grids in Back box. Choose the General Preferences dialog box and check Disable Auto Add/Delete box. If necessary, change the color of the grid so that it will be as visible as possible. Choose Show Grid from the View menu. Also choose Snap to Grid. Surround Make a new layer and name the layer "Triangles". Low poly drawings are usu- ally based on a series of triangles but any polygon shape will work. Set the stroke width to two points and the stroke to a color that is easy to see on the photo- graph. Set the fill to None. Choose the Pen tool and click a series of straight paths around the left edge of the face starting with the middle of the top of the head. Be sure that the paths connect at a point on the grid where the subdivisions intersect. When you reach the center of the chin, close the path through the ver- tical center of the face so that the left half the of the face is surrounded by the shape (see Figure 5). Make sure that the center path is perfectly vertical. Triangulate Carefully look at the photo and begin determining where the appropriate color breaks are. With the Pen tool, click a point on the grid close to the outline shape and then click an intersection point on the outline. Click another point on the grid and then close the path into a triangle (see Figure 6). Continue drawing tri- angles based on the grid intersections. The triangles should ideally encapsulate a small region of color and their sides Figure 5: When you reach the center of the chin, close the path through the center of the face so that the left half of the face is surrounded by the shape. Figure 6: With the Pen tool make the first triangle close to the edge path.
