look_at_origin

Builds a 4x4 rotation matrix suitable for `rgl::view3d(userMatrix = ...)`
that orients the scene as if the camera is at `eye` looking toward the
origin with z pointing up.

Plot brain atlases as interactive 3D meshes using 'Three.js'
via 'htmlwidgets', or render publication-quality static images through
'rgl' and 'rayshader'. A pipe-friendly API lets you map data onto
brain regions, control camera angles, toggle region edges, overlay
glass brains, and snapshot or ray-trace the result. Additional
atlases are available through the 'ggsegverse' r-universe. Mowinckel
