Jackie Turpin's tennis project starts with Nadal's serve

The nine seconds do a lot: Rafael Nadal's serve — the toss, the deep racket drop, the whip through contact — traced frame by frame into flat, hand-drawn shapes that move across a simple 3D ground plane. The reel is labeled a workflow test, and the caption makes it a promise: “there's been a tennis project brewing in the back of my mind,” Jackie Turpin writes, “and i feel ready to go for it.”

Turpin is an artist and animator who teaches in UCLA's Design Media Arts program, with a practice that already runs from performance to simulation. The test is a 2D-to-3D pipeline (the replies read it as Blender's grease pencil, the tool that lets you draw flat strokes inside three-dimensional space) and the point of rotoscoping an athlete is exactly the seam it exposes: hand-drawn motion carrying real human weight through a computed world.

That seam is load-bearing in games history. Jordan Mechner filmed family footage and traced it to give Prince of Persia its uncanny physical gravity, and the lineage is honored so directly that a pixel-art rotoscoping tool named itself after the trick — Killscreen covered Paint of Persia back when it appeared. A tennis serve is the same experiment at higher difficulty: the most slow-motion-replayed movement in sport, familiar enough that any wrongness in the weight reads instantly.

What the tennis project becomes — game, film, installation, some hybrid of Turpin's performance and simulation work — is left open. The test suggests the interesting answer is the seam itself. Worth watching.
