India ink on Bristol paper, 11x14" (frame not included)
I implemented a simple diffuse-lighting-based hatching algorithm and applied it to some low-poly 3D models. The hatches are applied in 2D screen space for consistent spacing in the final drawing.
Drawn with an AxiDraw V3/A3 pen plotter with a Koh-I-Noor Rapidograph technical pen on Strathmore Smooth Bristol paper. I number and initial each drawing by hand.
