The artist defines a set of $m$ example poses $p_1, p_2, ..., p_m$ and corresponding sculpted shapes $s_1, s_2, ..., s_m$. For every vertex $v$, we can calculate a delta vector $\Delta v_j = s_j(v) - v_lbs(p_j)$ for each example pose $j$. This $\Delta v_j$ represents the "correction" required at that specific pose.

Here is why this is an "interesting piece" of technical innovation: The artist defines a set of $m$ example poses $p_1, p_2,
For artists, digital sculptors, and students of human anatomy, high-quality reference material is the difference between a stiff, lifeless figure and a dynamic, believable work of art. Finding a "PoseSpace PDF" typically refers to the series—a library of professionally photographed, 360-degree figure references designed specifically for artists. : Published recently
